Applying systems thinking to knowledge mobilisation in public health
Health Research Policy and Systems volume 18, Article number: 134 (2020)
Knowledge mobilisation (KM) is a vital strategy in efforts to improve public health policy and practice. Linear models describing knowledge transfer and translation have moved towards multi-directional and complexity-attuned approaches where knowledge is produced and becomes meaningful through social processes. There are calls for systems approaches to KM but little guidance on how this can be operationalised. This paper describes the contribution that systems thinking can make to KM and provides guidance about how to put it into action.
We apply a model of systems thinking (which focuses on leveraging change in complex systems) to eight KM practices empirically identified by others. We describe how these models interact and draw out some key learnings for applying systems thinking practically to KM in public health policy and practice. Examples of empirical studies, tools and targeted strategies are provided.
Systems thinking can enhance and fundamentally transform KM. It upholds a pluralistic view of knowledge as informed by multiple parts of the system and reconstituted through use. Mobilisation is conceived as a situated, non-prescriptive and potentially destabilising practice, no longer conceptualised as a discrete piece of work within wider efforts to strengthen public health but as integral to and in continual dialogue with those efforts. A systems approach to KM relies on contextual understanding, collaborative practices, addressing power imbalances and adaptive learning that responds to changing interactions between mobilisation activities and context.
Systems thinking offers valuable perspectives, tools and strategies to better understand complex problems in their settings and for strengthening KM practice. We make four suggestions for further developing empirical evidence and debate about how systems thinking can enhance our capacity to mobilise knowledge for solving complex problems – (1) be specific about what is meant by ‘systems thinking’, (2) describe counterfactual KM scenarios so the added value of systems thinking is clearer, (3) widen conceptualisations of impact when evaluating KM, and (4) use methods that can track how and where knowledge is mobilised in complex systems.
Knowledge mobilisation is concerned with generating robust and useful knowledge and facilitating its movement and use in arenas where it can do most good . This knowledge is often informed by diverse sources and is shared multi-directionally . While knowledge mobilisation is well recognised as a vital strategy in efforts to improve public health, the ways in which it is theorised and operationalised vary widely, reflecting influences from different disciplines and paradigms [3, 4]. We make the case that systems thinking should be one of these influences. Systems thinking adds value because it offers productive ways of understanding and working with the multiple complexities that knowledge mobilisation strategies face. These include: 1. “Wicked” intractable public health problems that have multiple interacting causes and are characterised by uncertainty and conflicting values and views [5,6,7]; 2. Messy policy and practice environments which are constrained by competing demands and expectations, politicised decision-making and uncertainty [8, 9]; and 3. The dynamic nature of the open systems within which policies and programs are implemented [10,11,12,13,14]. Health is a property of many such systems including education, transport, the environment, housing, food systems, welfare systems and the economy . Efforts to mobilise knowledge in public health policy and practice must take account of this complexity [5, 16,17,18,19].
Systems thinking has gained traction as a valuable approach to tackling complex problems as it offers concepts, tools and frameworks that have the potential to strengthen and complement knowledge mobilisation practice and research [20,21,22]. However, there is a long way to go in exploiting its full potential . This commentary seeks to investigate how systems thinking changes the ways in which knowledge mobilisation is conceptualised and operationalised. We argue that systems thinking can do much more than enhance knowledge mobilisation: it can transform perceptions of what knowledge is, how it is created and valued, and how it is (and could be) used. Our aim is to move beyond description and theory to identify practical strategies, including examples of how systems approaches have been applied. We lay the groundwork by first offering an overview of the relationship between knowledge mobilisation and systems thinking, and then exploring three questions:
How can systems thinking advance knowledge mobilisation?
What does systems-informed knowledge mobilisation look like in practice?
What’s next for advancing systems-informed knowledge mobilisation?
We introduce key concepts, including frameworks for (a) understanding knowledge mobilisation (KM), based on eight empirically-derived archetypes of KM practice , and (b) using systems thinking to leverage change in complex systems (Fig. 1). We then describe how these frameworks interact (Table 1)—providing guidance for operationalising the ideas—and draw out some learnings.
The relationship between KM and systems thinking
What is knowledge mobilisation for public health?
Knowledge mobilisation refers to a broad set of activities that,
“… help move research results into society, as well as bring new ideas into the world of research. From knowledge-brokering and outreach, to more effective dissemination through new technologies, to the ‘co-creation’ of knowledge, these processes help ensure that public investments in ... research have the greatest possible impact—intellectually, socially and economically.” (:12)
In public health, knowledge mobilisation (KM) focuses on impacting public policy as well as health service management and practice. There is widespread agreement that research-infused knowledge should inform policy and practice but systems and structures are often very poor at facilitating this. As Boaz et al argue, “KM is in everyone’s interests and no-one’s job description, and everyone blames everyone else for its absence” .
There is also debate about what forms of knowledge should be mobilised, how and with what aims. Echoing the changing discourse about evidence-based policy, the dominant conceptualisation of how knowledge is shared has moved from a linear model towards multi-directional and complexity-attuned approaches where knowledge is produced and becomes meaningful through social processes [3, 27]. The literature on Mode 2 knowledge production  and work by Graham, Ward, Nutley, Holmes and others (e.g. [2, 4, 20, 38, 126, 127]) emphasises that knowledge is not independent of systems, processes or people and that context, co-design, power relations and different ways of knowing are key constructs. The evolution of terminology (e.g. transfer, translation, exchange, diffusion, integration and mobilisation) illustrates this well  (although the proliferation and inconsistency of terminology has also been noted ). Similarly, what is being mobilised is increasingly conceptualised more broadly as knowledge rather than research or evidence. This recognises that policy and practice are necessarily informed by a fusion of locally interpreted information, ideas and values from multiple sources, only some of which stem from academia [129, 130]. We use the term knowledge mobilisation here because it seems the most fluid and inclusive option for capturing what occurs in real-world settings. The influence of, or overlap with, systems thinking can be seen in this evolution but, as we will show, there are further contributions that systems approaches can make to inform or reconceptualise contemporary understandings of KM practice.
What is systems thinking?
Systems thinking in public health is a broad conceptual lens informed by a multidisciplinary body of theories, tools and methods [32, 49, 97, 131]. It posits that the world is comprised of complex systems which are dynamic, interconnected and evolving, and cannot be controlled, so they must be better understood if we are to effect desired change [10, 16, 132, 133].
A system is a perceived collection of interrelated but independent parts that are linked by a common purpose and, through their interactions, function as a whole (see Box 1.). It includes the range of actors, activities and settings that appear to have direct or indirect influence on (or be affected by) a given situation [112, 134]. Systems that impact public health may include communities; coalitions and networks; school, hospitals and other government services; policy agencies that work at local, state and national levels; and broader economic and political systems that impact on how wealth and health are created and distributed.
Systems thinking makes a crucial distinction between simple, complicated and complex phenomena. Where systems (and the problems they produce) are simple or complicated they are relatively linear, deterministic and stable with few interdependencies. In these relatively ‘knowable’ situations, planned KM strategies with fixed outcomes may be most appropriate. Where they are complex, however, they are non-linear and dynamic, adapting unpredictably in response to feedback and thus often undermining ‘logical’ efforts to bring about change [64, 119]. In these situations, systems approaches to KM are likely to be most valuable because they invite a multi-perspective, emergent view of the phenomena.
Systems thinking has an increasingly strong presence in the public health literature with near-exponential growth in recent years . For many, it offers valuable perspectives, tools and strategies for better understanding problems in their settings and, potentially, for strengthening policies so that they are more inclusive, effective and resilient [14,15,16,17, 24, 29, 32, 146,147,148]. However some authors note that the contribution of systems thinking to improving public health quality or intervention effectiveness is not yet clear or convincing, suggesting that it may be a passing fad offering little more than a compelling metaphor [138, 149,150,151]. This may be, in part, because it is currently underutilised and under-studied .
Using systems thinking to leverage change in complex systems: a framework
Systems thinking encompasses socio-ecological models within which health problems and solutions are conceptualised as multi-level phenomena involving individuals, groups, organisations and wider systems at sector and societal levels . But it also draws attention to the structures, interactions and forces that operate within and across social layers and shape causality . Systems approaches focus on patterns of inter-relationships, rather than independent forces, as the leverage points for intervention [76, 132, 152].
Malhi and colleagues  (who adapted work by Meadows [32, 132]) and Kania et al., suggest six key areas or leverage points to target when applying a systems approach to organisational change. Each of these areas raises questions for practicing KM:
What are dominant mental models in this system? What assumptions are held about how the system works and should work? How can these values and beliefs best be leveraged (or challenged) in efforts to mobilise knowledge?
What do people believe are the key aims of this system, its overall purpose? Are the espoused goals congruent with what really drives people? In what ways do current goals and past achievements align with the goals of KM? How can ‘goals of goodness’ (aiming for positive practice) be enhanced in this context?
Structure and rules
What are this system’s organising foundations (including infrastructure, and rules such as policies and guidelines)? How do they shape knowledge practices and opportunities? How do past experiences impact the present and possible futures? What changes in structure or rules might best support the system to self-organise productively in relation to KM?
Relationship and power
What types (and quality) of connections are there within and between people and institutions? How do roles and decision-making powers influence change trajectories? What opportunities are there to create new roles and relationships, leverage existing relationships, and address power imbalances?
What forms and channels of information help patterns of change to remain stable in this system? Which cause patterns of change? How can existing feedback channels be used (or new ones created) to generate engagement with KM efforts, and to sustain desired change?
Actors and elements
What people, practices, resources, and physical elements comprise this system? Interventions that target discrete parts of a system are often ineffective in creating system-wide change (or require many actions at this level) so is this the most effective strategy? If so, what else needs to be done?
As Fig. 1 indicates, these areas are conceptualised as a hierarchical framework in which change is harder to achieve at the upper levels but, if successful, is likely to be more transformational. Systems change will usually require action at multiple levels, often simultaneously, but this framework can guide decisions about where best to focus efforts and what sort of strategies might be most successful.
In the next sections we explore what systems-informed KM might look like and offer suggestions as to how that could be operationalised in public health policy and practice.
What is the current relationship between systems thinking and knowledge mobilisation in public health?
Systems thinking has a growing presence in KM discourses [3, 20]. Commentaries recognise that not only are public health problems and solutions shaped by the forces of complex systems, but so is the practice of KM itself. From this perspective, KM is also emergent, highly relational and profoundly context dependent . A systems approach to KM may include identifying who (or what) has the power to influence which forms of knowledge are valued and used, and recognising that KM efforts can create ‘push back’ from a system, resulting in unexpected and counterintuitive outcomes . As we argue below, systems thinking can significantly recalibrate the scope of strategies and targets associated with mobilising knowledge to inform public health policy and practice.
Systems thinking yields strategies that improve the value, reach and impact of knowledge [20, 62, 134, 153]. This includes knowledge about the co-benefits of policies and programs that address the complexity of entangled and syndemic public health problems [10, 32, 33]. Empirical studies indicate that intervention outcomes are positively associated with strategies that address the complexity of processes and conditions they are trying to improve. For example, studies of 124 interventions tackling congestive heart failure, type II diabetes and hospital readmission rates found greater effectiveness when the interventions targeted two or more characteristics of complex systems (including interdependencies between people, resources, processes and structures), and when they allowed the implementation to evolve responsively over time [141, 154, 155]. These intervention designs were congruent with systems principles but not explicitly informed by them. This suggests that systems ideas may be having an ‘enlightenment’ effect : seeping into policies and programs by influencing underlying mental models rather than directing conscious choices.
System thinking has inspired whole-school level co-production approaches to primary prevention. Cluster-randomised controlled trial methods have shown these to have greater effect sizes in reducing adolescent smoking and drug and alcohol use than conventional (health curriculum) methods [157, 158].
Other empirical studies indicate that systems thinking can significantly improve leadership performance and organisational efficiency , and is integral to effective project management  and organisational crisis responses . Systems approaches can also optimise specific practices such as improving the use of organisational level knowledge , co-producing research, network formation, fostering ‘bottom-up’ innovation, implementation and scaling-up . Single studies have found that local solutions implemented flexibly by frontline staff, and supported by reflexive learning and discussion, improved patient safety in five hospitals . Willis et al. describe how systems approaches underpinned a large-scale healthcare transformation tackling improvements in surgical redesign, primary care and quality improvement . Systems thinking has also been used in process evaluation to develop explanatory understandings of complex relationships between individual interactions and health organisation structure and functions .
Despite this growing body of evidence about the value of systems approaches for addressing complex problems, and calls for applying system thinking to KM in public health, the actual practice of KM has not necessarily changed . For example, a recent global survey of 106 research organisations found that most of their KM strategies focused on ‘pushing’ their own research (a strategy the authors call “disseminate and hope”) with very little use of strategic ideas from the literature that “take account of competing definitions of knowledge, the internal and external contexts, the parties involved, the organisational factors and the political dynamics” . This may be in part because dominant KM and implementation frameworks do not currently take account of core concepts in systems thinking such as unpredictability and emergence, dynamism and the need for local autonomy [142, 163]. Further, the literature on applying systems approaches to KM in public health policy and practice has few operational models or in-depth case studies, and minimal practical guidance on how it should be done [3, 134]. We seek to address this gap.
1. How can systems thinking advance knowledge mobilisation?
Davies and colleagues  describe eight archetypes of KM practice that were derived inductively from an extensive literature review and empirical investigation of practices used in organisations that aim to mobilise knowledge for policy and/or practice (including website review of 186 international agencies, in-depth interviews with agency leaders, a web survey and deliberative workshops with stakeholders). These archetypes integrate the patterns of KM assumptions, activities, configurations and rationales observed across the agencies and can be used to map the breadth of KM and its basic architecture . Impacting policy is considered an outcome rather than a practice in its own right.
We now explore the contribution that systems thinking makes to each of these archetypal practices, and reflecting on how a systems approach might further extend, strengthen or transform them.
Archetype 1: Producing knowledge
This archetype includes the production and dissemination of research-based products such as empirical research papers, systematic reviews, research summaries and syntheses and web portals. Its focus is on instrumental, knowledge-driven problem solving.
Traditionally, knowledge production has been viewed as an exclusively scientific endeavour, separate to the knowledge transfer processes that followed it. The dominant scientific mode (which privileges internal validity, objectivity, reliability and generalisability) has produced robust knowledge that has advanced many areas of public health, but it has some important limitations for addressing policy and practice problems where complexity is a defining characteristic [30, 130, 164,165,166].
With its focus on interaction and dynamism, systems thinking demands that knowledge production grapples with real world contexts . It is methodologically pluralistic and creative, designing new methods to address complexity . It also integrates theories, ideas and views from multiple sources so is usually transdisciplinary and collaborative [24, 62, 71]. For example, the emphasis on ‘What works?’ is shifting to take account of much broader questions exploring social impact, causality and equity , and how best to include the voices of people whom this knowledge is intended to benefit . Systems thinking (in common with some other approaches, e.g. participative action research ) makes this explicit by asking how knowledge production and use reflects community needs and attends to local and institutionalised values and power inequities [45, 50, 89]. This expands and changes what we focus on, how we conduct the research, how it is integrated with values and other forms of knowledge, how we try to implement it, and who is involved. Ultimately, it reconceptualises what we mean by knowledge and by “good evidence ”.
Archetypes 2 and 3: Brokering and intermediation
These two archetypes describe relational models for promoting research flow and use. Key activities include tailored dissemination, education, and the creation of interactive spaces for researchers and policymakers/practitioners. Archetype 2 focuses on brokering new local research, while archetype 3 focuses on brokering wider bodies of existing research.
Intermediaries have a vital role to play in brokering and championing new knowledge and the strategies used to mobilise it within local contexts . This is well established in the wider KM literature (e.g. [169, 170]). Systems thinking adds to this by emphasising that public health problems are the products of complex social, economic, political and institutional forces . This encourages mobilisation efforts to break down silos, integrate different forms of knowledge, and facilitate its use synergistically across different layers and sectors of government [15, 24]. So, from a systems perspective, intermediary roles are less about ‘bridging gaps’ or packaging and ‘transferring’ research findings, and more about ‘blurring the boundaries’ between groups and enabling a more continuous process of knowledge exchange as part of everyday practice [69, 171]. This can involve building capacity, creating hybrid roles, harnessing local champions and communication channels, bringing people together, and developing shared vocabularies, knowledge and objectives. Several studies illustrate the benefits of collaboratively generated visual models and maps as ‘boundary objects’ that provide a focal point for such activities [58, 62, 79].
Archetype 4: Advocating evidence
This archetype describes proselytising for evidence-informed action in which interaction is central. Activities include education, social influence, forging alliances, and the use of incentives and reinforcements. Advocacy recognises that knowledge use is socially situated and so aims to reduce structural, organisational and cultural barriers to desired health outcomes.
Public health advocates tend to be systems thinkers whether or not they use that term. They analyse systems to identify power structures, vested interests and leverage points; mobilise important stakeholders and the media to put pressure on these points; and ‘frame’ their communications to target and change prevailing mental models . For example, the advocacy coalition framework recognises that political change is complex and uncertain, thus the need for “policy learning” and cross-system efforts to influence feedback loops, values and beliefs . The anti-tobacco movement is notable for its success in denormalising smoking using complementary strategies to target legislation, public perceptions and industry misinformation . Such approaches deliberately engage with multiple levels of systems as illustrated in Fig. 1.
Archetypes 5 and 6: Getting research into practice and researching in practice
Archetypes 5 and 6 describe hands-on support for local implementation, developing networks and building local knowledge capacities. Archetype 5 focuses on improving practice through the application of research from outside the organisation where change is sought. This may emphasise ‘transfer’ of explicit knowledge, but its adoption can also include local adaption and contingencies. Archetype 6 focuses on producing knowledge within the organisation. Key activities may include local learning, capacity development and co-production.
KM has tended to be conceptualised as a staged activity with models that focus on rational cognitive processes and linear ‘transmission’ routes (e.g. pipelines, ladders [173, 174]). Increasingly however, the KM literature recognises that the use of knowledge is contingent, dependent on perceptions of credibility, legitimacy and political acceptability which are shaped by epistemological beliefs, ideology and changeable local conditions [175, 176]. As Nutley et al. argue,
… there is no simple answer to the question of what counts as good evidence. It depends on what we want to know, for what purposes, and in what contexts we envisage that evidence being used .
Systems thinking builds on these developments by introducing the concepts in Box 1 which have profound implications for development, implementation and evaluation of policies and programs. Interdependence, self-organisation and emergence means that leveraging change in one part of the system will lead to desired outcomes only if the right concurrent shifts happen in the system’s wider relationships and structures , and thus mobilisation strategies cannot always be planned and implemented with predictable effects [14, 136]. For example, from a systems perceptive, interventions will scale-up more effectively if they are conceptualised as provisional plans for action that work with variation across local contexts, striving to harness the self-organising and sensemaking capacities within intervention settings [11, 144]. This involves a ‘bottom up’ approach of working closely with stakeholders, fostering local champions and providing strategic feedback for ongoing problem-solving and adaption [104, 144].
A systems lens on archetypes 5 and 6 also changes how we understand and study implementation fidelity. Hawe argues that interventions are not replicated in the same forms across complex systems, rather, what gets transferred are the intervention’s core principles  or what some call its “powerful ideas” . This means rejecting the traditional doctrine of precisely implementing intervention components (its form or surface structure) and instead focusing on fostering and evaluating local adaption that is consistent with the intervention’s theory of change (its function or deep structure )[29, 64, 101, 178, 179]. The contribution of systems thinking to this burgeoning “science of intervention adaptation”  can be to distil the essence of an intervention, design more fit-for-purpose methods to embed it, enhance its local effects, and help evaluate it . This highlights a need for qualitative methods that can capture and use emergent knowledge generated in the adaptation process (e.g., what is the new knowledge about, for what purpose, in what form, used by whom and how?).
When intervention design and implementation are poorly integrated, interventions may be ill-suited to local populations and settings, resulting in implementers having no sense of investment or ownership, and a poor understanding of how to deliver their core functions [94, 180]. Collaborative problem-identification and intervention design (which includes those implementing and receiving the intervention), together with fostering local adaptation, are systems-informed responses to this enduring challenge [14, 105, 180].
Archetype 7: Fostering networks
This archetype describes the creation, development or facilitation of linkage and collaboration to shape and share expertise and increase the role of research-based knowledge. Knowledge from within, and external to, the organisation/network is used, and attention is paid to tacit and local knowledge. Knowledge production and/or dissemination is combined with social influence and facilitated interaction.
The wider KM literature draws attention to the significant epistemic and cultural differences between the worlds of research, policy and practice [181,182,183], and to the detrimental effects of silos within health research itself . Thus many agree that cross-sector and transdisciplinary networks, including communities of practice, are key to effective KM [26, 42].
Systems thinking adds to this by exploring how networks of people or organisations exchange information to work together, and how network structures change across time and new structures emerge. It highlights the benefits of operating both vertically (connecting layers of government and health systems) and horizontally (connecting sectors) [15, 59]. Strategies for fostering networks build on and ‘nudge’ existing connections and dynamics, and strive to develop feedback mechanisms for engagement and exchange [39, 56]. Viewing formal collaborations as networks also invites boundary critique: asking who and what will be included in the enterprise, and what this means for equity and the values (and ‘facts’) that are represented [49, 50, 185]. This goes well beyond a focus on disciplinary boundaries to consider the institutional, epistemological and political boundaries that impact on knowledge sharing and use . Boundary critique requires explicit justification of choices and fostering participation by stakeholders who may be marginalised by existing structures and processes .
Archetype 8: Advancing knowledge mobilisation
This last archetype describes attempts to develop a coherent theoretical foundation for KM and to evidence it with robust empirical evaluation. The aim is to refine the field, build shared understandings, generate commitment to further study and reflexively apply “knowledge about knowing”.
Systems thinking advances KM as a field by shining a lens on the complex, real-world contexts in which knowledge is produced, set in motion and used. For example, it tells us that KM contexts are interdependent and dynamic so that effective KM is likely to be multifaceted, iterative and adaptive. Consequently, these archetypes have fuzzy boundaries and should be employed complementarily depending on circumstances and goals. Systems thinking also goes beyond these archetypal practices. It promotes a paradigm that questions what knowledge is, how it should be generated, the contexts and processes in which it is used, methods for mobilisation, what impacts we can hope to achieve through KM efforts and how they should be evaluated [14, 56, 59, 144, 148, 163]. KM is no longer conceptualised as a discrete piece of work within wider efforts to strengthen public health, but as integral to and in continual dialogue with them .
The influence of systems thinking becomes more prominent as these archetypes progress. In the first three (producing knowledge, brokering local research and brokering bodies of research) research knowledge tends to be treated as an exemplary product that has some independent value. This construes KM as a complicated practice in which reduced barriers or enhanced enablers will facilitate knowledge use . In the latter four archetypes, knowledge is positioned as more dynamic and imbued with value (or not) through a social process of negotiated sensemaking and local adaption. Here, context is foregrounded and knowledge is both generated and used by those with very different forms of expertise . Values, rhetoric and tacit knowledge gleaned from personal and professional experiences are part of the mix [11, 144, 188]. These archetypes, therefore, tend to construe KM as complex. This highlights the existing influence of systems ideas but also suggests the need for a coherent systems-informed approach if KM is to achieve its potential.
2. What does systems-informed knowledge mobilisation look like in practice?
Table 1 presents an overview of how systems thinking can inform strategies and intervention points for KM. It explores the archetypal KM practices described above in relation to the systems change framework depicted in Figure 1 and the questions raised by KM in each area of the framework. The purpose is to provide practical guidance about the range of considerations that may be useful when planning, developing and implementing KM strategies for complex problems.
The ideas and recommendations in this table are not new; many of them are currently used by individuals and organisations, albeit variably and often without a systems label. The content is also not definitive; others will have different ideas and may challenge some of our assertions. Many of the concepts and strategies in the table have roots in other traditions and are thus not the sole property of systems thinking, but are potentially repositioned or given new force when KM is viewed through a systems lens . It may be considered somewhat paradoxical to use a table to describe complex interdependent phenomena, but tables are familiar communication devices that enable information to be distilled efficiently. In this table, dotted lines between rows and columns indicate permeable boundaries and potential fuzziness in the distinction between concepts or even in which cell they should sit.
The strategies to support systems-informed KM as outlined in Table 1 should also be underpinned by a healthy humility that recognises the complexity and unpredictability of the systems within which public health problems are created and solved, and how the perspectives of different actors, including ourselves, are invariably limited . This suggests that collaboration/co-production, empowering stakeholders and continual learning about the interactions between context and mobilisation activities are cornerstones of this work. As noted previously, such ideas are not exclusive to systems thinking, but they are elevated by it. We expand on this below with some examples of practical tools and application:
Systems thinking moves the context into the foreground . It demands that we understand what local needs look like, the meanings attached to different forms of knowledge, how it moves around the systems, and how knowledge is constrained or gains legitimacy, including key agencies, actors, systems structures and dynamics. This helps the development of contextualised theories of change, indicates possible leverage points and strategies, indicates where best to draw the system’s boundaries and aligns expectations with local realities [14, 59, 64, 66, 78, 112, 116]. It also raises questions about how knowledge claims can be established, e.g. what forms of interrogation about accuracy and authority are appropriate? This nudges the focus of KM strategies towards the more interactive and participatory activities associated with the latter archetypes.
In many cases, contextual understanding will require explicit systems analysis. Examples of systems analysis methods and tools include concept (or systems) mapping [60, 61], dynamic systems modelling , and social network analysis [24, 25, 64]. These approaches are often used as the starting point for stakeholders to come together for collaborative KM. When visual representations of systems are co-produced (e.g. behaviour-over-time graphs, causal loops, stock–flow diagrams and simulations) they support joint problem-framing and diagnosis, help identify solutions and motivate those involved to take action on proposed solutions .
Collaboration and co-production
A central feature of the systems approach across all the archetypes is cross-sector deliberative collaboration (or co-production) with key stakeholders. This is demanding terrain. Challenges include the need for additional time and resources, and management of power inequities and conflicting values and priorities . Collaboration is not always appropriate or feasible so other forms of participation may be preferable in some circumstances . Some argue that collaborative research has the potential to harm reputations, relationships and research integrity . Empirical studies have found that genuine co-production is hard to achieve in practice  and that partnerships can be plagued by distrust, inertia and antagonism . There is little guidance about how best to constitute and support collaborations as (and within) dynamic systems.
Yet others report that collaboration (and closer relationships in general) can combat distrust between epistemic groups . Collaborative relations provide critical nuance by eliciting stakeholders’ tacit, experiential knowledg e, increase the perceived relevance, applicability and legitimacy of knowledge thereby facilitating its use in policy and practice, and can increase accountability and investment by those who are best positioned to champion or facilitate strategies at the local level [16, 25, 28, 94, 143, 193,194,195]. The mechanisms for collaboration are relatively well understood [122, 123, 196] and there are many examples of where it has been used effectively for knowledge mobilisation. These include cross-sector partnerships to empower first nations people [51,52,53]; intra-organisational collaboration that generates ‘frontline ownership’ by healthcare providers ; co-developed equity indicators used by public health agencies to address social determinants of health ; cross-sector social learning platforms that have tackled health promotion, food security, campus health systems and tobacco control ; stakeholder co-production of a framework for natural experimental evaluation of a levy on soft drinks ; and a national partnership using systems science to prevent chronic disease [40, 123]. Bammer  describes tools for identifying levels of collaboration, for stakeholder analysis and knowledge synthesis, and for understanding value conflict and compatibility.
Addressing power imbalances in how knowledge is constituted and legitimised
Systems thinking across all the KM archetypes also invites consideration of the insidious detriments of formal and informal power inequities, including the influence of vested interests [45, 50, 85]. We need to ask questions about how knowledge is constructed, whose knowledge is being mobilised for what purpose and whose gain, and what our own role is within that dynamic [2, 86]. Collaboration with those who are disempowered is essential; especially with people who have been structurally disadvantaged [51,52,53]. Examples at the micro level that illustrate how different perspectives (knowledge) can be brought to the table include paying for first class disability train tickets so that stakeholders with disabilities can participate in workshops , using empowerment techniques to support young homeless people to generate service design proposals , and linking community members with researchers in a buddy system . At the meso levels, strategies may involve modifying roles or procedures within an organisation , establishing advisory bodies comprising members of disenfranchised communities , or using citizen juries, deliberative polls or boundary organisations and objects . Beyond this, participatory action research methods are designed to retain the voice and control of those typically marginalised .
To mobilise knowledge within self-organising, dynamic and unpredictable systems, we need to engage in continuous learning and adaptation to identify and nurture emergent local responses. This is exemplified in archetype 6 (researching in practice) but also applies to brokering knowledge, advocacy, implementation and fostering networks. The value of reflexive learning-in-practice is emphasised by Brown and Duguid  who differentiate between modus operandi (the way a task looks to someone working on it as it unfolds over time when “many of the options and dilemmas remain unresolved”) as opposed to opus operatum (the way a finished task appears in hindsight). Opus operatum, they argue, focuses on the task and glosses over the process of doing which is structured by changing contextual conditions. This means that as a work process becomes more complex, our post-hoc depiction of it increasingly obscures what actually needs to be done. Close attention to modus operandi is needed to understand how knowledge is (and can best be) generated, shared and used.
Adaptive learning requires observation and understanding of the flow-on effects and feedback loops of intervention. This incorporates ‘trial and error’ learning, using fit-for-purpose methods to understand the subtleties of the system’s dynamic behaviours , and reflexive practices founded on organisational learning principles [76, 89]. Implementation strategies should be loosely specified while attached to clearly defined goals so they can be locally adapted for maximum effect and incorporate ‘bottom up’ expertise and innovatio n[98, 99]. Intervention ‘fidelity’ is thus indicated by the presence of underlying principles, or through the achievement of goals, rather than by faithful adherence to standardised strategie s[64, 201]. Evaluation that informs on-going mobilisation efforts (e.g. developmental evaluation) is warranted . Peters calls this commitment to testing and continuously revising strategies a “scientific habit of mind” .
3. What’s next for advancing systems-informed knowledge mobilisation?
There are several challenges in applying systems thinking to real-world KM practice. First, the evidence-base for the effectiveness of systems thinking in KM is nascent and scattered, in part because systems approaches are diverse and applied very differently [202, 203]. There are calls for further empirical research  including in-depth case studies and cross-case analyses, realist research and meta-ethnographie s[3, 126, 134, 138, 205]. Most pressingly, we need to answer the question, ‘How do we know when systems thinking has enhanced KM?’ But generating high quality systems evidence may require new methodologies and new ways of thinking about health and its interconnections with society and the environment [33, 197, 206]. As Rutter at a l. argue, “Existing approaches to the generation and use of evidence remain necessary, but are not sufficient”. The turn to realist, narrative and ethnographic methods in public health reflects this shifting terrain, but we are yet to realise the impacts of this next phase of engaging with complexity .
Second, system thinking is conceptually and operationally challenging . It counters many familiar approaches  and much of the literature is abstract and theoretically dense [131, 137, 150]. Organisational and individual capacities for using systems theory may be limited [55, 208] and impeded by the often confusing terminology and definitions [46, 204]. Policy partners can experience political pressure to identify simple, easy-to-explain and quick-to-implement solutions  using familiar methods . Such challenges may be exacerbated by a lack of professional incentives for cross-sector collaboration , perceptions that systems approaches are more resource intensive than traditional methods, and the often longer timeframes they require [187, 195].
Third, there are no universal indicators or standards for good systems-informed KM practice. The KM literature often fails to identify tangible or measurable outcomes, or even to explain the nature of the knowledge that is to be mobilised . There is emerging agreement about the scope and tasks of KM (as illustrated by the archetypes described above ) but systems thinking indicates that they are not fixed: KM practices need to be deployed in myriad configurations depending on the local context and goals (see also [31, 142] who identify core skills for transdisciplinary KM). Given the degree to which KM is influenced by power relationships and disciplinary traditions—each sensitive to different indicators and outcomes, and focused on different process paths—what counts as success, for whom and why, is invariably a contentious value-laden issue [17, 85, 209]. Some systems thinkers refute the notion of ‘best practice’ within complex, dynamic contexts – an assertion that might equally apply to KM practices [92, 114]. Thus, while many principles for systems-informed KM may be transferable, a suite of tightly specified practices is unlikely to be applicable in all contexts and circumstances [56, 187].
We make four suggestions for advancing systems-informed knowledge mobilisation:
Be specific about what is meant when using the term ‘systems thinking’. What key ideas or methods are included? For what KM purposes? How are they (to be) operationalised? For example, developing systems maps or models is not the same as co-production - they might be done together or separately but with different likely impacts.
Describe counterfactual scenarios in KM so the added value of systems thinking becomes clearer. For example, is a systems approach providing an alternative to a specific model of ‘business-as-usual’ (e.g. one using a linear logic model)? Or is it supplementing (or replacing) another form of collaborative problem solving such as community development?
When evaluating KM, cast the net widely to capture impact. Any intervention which activates the agents in a system will have different effect sizes in different contexts, and may also impact different associated problems [29, 210]. This means that effects and the knowledge employed or generated in their production will take time, care and resources to track thoroughly.
The uncertainty created by complexity is exacerbated when there is poor understanding of how and why change occurred. Use methods that can track KM effectively in complex systems. A key strategy is to make more visible the mechanisms of KM practice, and the short- and long-term impacts of interventions. Careful monitoring and reporting, theory-driven evaluation and process evaluation that utilises qualitative methods can make important contributions to understanding and explaining what occurred [46, 66, 144, 157, 211].
This paper explores the contribution that systems thinking makes to the planning and implementation of KM in public health policy and practice and suggests areas where there is further potential for value gains. By applying a systems thinking framework to a suite of KM practices, we develop an argument that systems thinking not only enhances but fundamentally transforms KM. It changes what we mean by knowledge, identifying it as a process as much as a transferable product. Knowledge here is pluralistic, informed by multiple parts of the system and reconstituted through use. This contrasts with traditional conceptualisations of exemplary knowledge remaining unchanged through use (fidelity). Systems thinking also changes what we mean by mobilisation – repositioning it as a socially situated, non-prescriptive and potentially destabilising practice that is contingent on addressing power dynamics and on continual adaptive learning about interactions between mobilisation activities and context. KM is no longer conceptualised as a discrete piece of work within wider efforts to strengthen public health, but as integral to and in continual dialogue with those efforts. The challenges presented by systems-informed KM are also very real but, as Braithwaite and colleagues argue, “we must grapple with the world we actually inhabit, not the one we wish we did” . We make four suggestions to facilitate constructive debate and further develop empirical evidence about how systems thinking can enhance our capacity to mobilise knowledge for solving complex problems. These include being specific about what is meant by systems thinking and how it has been operationalised; including counterfactual KM scenarios so the added value of systems thinking is clearer; widening the conceptualisations of impact when evaluating KM to capture a range of systems effects; and using evaluation methods that can effectively track KM in complex systems.
