Program theory and logic models for systemic evaluation International Conference on Systemic Approaches in Evaluation Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) Eschborn, Germany 25-26 January 2011 Patricia Rogers Patricia.Rogers@rmit.edu.au
Overview Presentation: Simple, complicated and complex systems 7 aspects to consider for evaluation Examples How these aspects have been addressed in some recent examples of program theory Discussion What recommendations of practical relevance can be made? How to develop it further? How to create the preconditions for systemic evaluations (if it is considered desirable) Recommendations for Evaluators Managers of evaluations Donors 2

Some definitions Program theory An explicit theory of how an intervention contributes to the intended or observed outcomes, which has 2 components: Theory of change Theory of action Logic model Program theory evaluation The process by which change comes about (for an individual, organization or community) How the intervention is constructed to activate the theory of change A visual representation of a program theory, usually in a diagram but sometimes in a table An evaluation that is at least partly guided by an explicit program theory. It is not necessarily driven by the theory, since it should be driven by its intended purpose and the needs of its intended users Funnell and Rogers Purposeful Program Theory 4
What people sometimes assume you mean by logic models that address complexity Funnell and Rogers Purposeful Program Theory 5
Two framings of simple, complicated and complex Simple Complicated Glouberman and Zimmerman 2002 Kurtz and Snowden 2003 Tested recipes assure replicability Expertise is not needed Success requires high level of expertise in many specialized fields + coordination Complex Every situation is unique previous success does not guarantee success Expertise can help but is not sufficient; relationships are key The domain of the known, Cause and effect are well understood, Best practices can be confidently recommended, The domain of the knowable Expert knowledge is required, The domain of the unknowable, Patterns are only evident in retrospect.

What constitutes a systemic approach to evaluation? Attention to: Inter-relationships Perspectives Boundaries Williams B. Imam I.

Aspects of complicated and complex situations and interventions with potentially important implications for evaluation 1) Focus 2) Governance 3) Consistency 4) Necessariness 5) Sufficiency 6) Change trajectory 7) Unintended outcomes Funnell, S.C. and Rogers, P.J. (2011) Purposeful Program Theory. San Francisco: Jossey-Bass/Wiley. 9
(1) Focus Simple Single set of intended outcomes/impacts Complicated Complex Different intended outcomes/impacts intended by different partners/stakeholders Different intended outcomes/impacts at different levels Emergent intended outcomes/impacts 10
Simple focus Intervention that produces single set of outcomes Intervention Shorter term outcomes Longer term outcomes 11
Complicated focus (1) Intervention that produces different outcomes valued by different stakeholders INTERVENTION SHORT-TERM OUTCOMES LONG-TERM OUTCOMES DIFFERENT LONG-TERM OUTCOMES 12
Complicated focus (2) Intervention that produces different outcomes at different levels Intervention Activities at system level Shorter term outcomes at system level Longer term outcomes Activities at site level Activities at client level Shorter term outcomes at site level Shorter term outcomes at client level 13
Complex focus (1) Intervention that produces emergent intermediate outcomes Funnell and Rogers Purposeful Program Theory 14
Complex focus (2) Intervention that produces emergent long-term outcomes Funnell and Rogers Purposeful Program Theory 15
(2) Governance Simple Single organization Complicated Specific organizations with formalized requirements Complex Emergent organizations working together in flexible ways Funnell and Rogers Purposeful Program Theory 16
(3) Consistency Simple Complicated Complex Implement what has been identified as best practice or evidence-based practice what works Classify the situation and implement what has been adapted for that context what works for whom in what situation Ongoing adaptation to emerging conditions what is working here 17
Complex consistency Adaptive, responsive intervention INTERVENTION SHORT-TERM OUTCOMES LONG-TERM OUTCOMES 18
(4) Necessariness Simple Complicated Complex Only way to achieve the intended impacts One of several ways to achieve the intended impacts which can be identified in advance One of several ways to achieve the intended impacts which are only evident in retrospect Funnell and Rogers Purposeful Program Theory 19
(5) Sufficiency Simple Complicated Complex Sufficient to produce the intended impacts. Works the same for everyone Only works in conjunction with other interventions (previously, concurrently, or subsequently) and/or only works for some people and/or only works in some circumstances which can be identified in advance Only works in conjunction with other interventions (previously, concurrently, or subsequently) and/or only works for some people and/or only works in some circumstances which is only evident in retrospect Funnell and Rogers 2010 Purposeful Program Theory.

Complicated necessariness (1) Multi-stage intervention (eg Outcome Mapping) Intervention Shorter term outcomes A different intervention Longer term outcomes Funnell and Rogers Purposeful Program Theory 22
Complicated necessariness (2) Intervention that works in combination with other interventions INTERVENTION SHORT-TERM OUTCOMES OUTCOMES/ IMPACTS ANOTHER INTERVENTION SHORT-TERM OUTCOMES ANOTHER INTERVENTION SHORT-TERM OUTCOMES Funnell and Rogers Purposeful Program Theory 23
Complicated necessariness (3) Intervention that works differently for different types of participants INTERVENTION SHORT-TERM OUTCOMES LONG-TERM OUTCOMES PARTICULAR PARTICIPANT CHARACTERISTICS INTERVENTION DIFFERENT PARTICIPANT CHARACTERISTICS DIFFERENT SHORT-TERM OUTCOMES DIFFERENT LONG-TERM OUTCOMES Funnell and Rogers Purposeful Program Theory 24
(6) Change trajectory Simple Complicated Constant, linear relationship between effort and results (eg twice the investment produces twice the results) Well understood but not linear relationship between effort and results (eg curvilinear dose-response relationship such as diminishing returns or too much of a good thing) Complex Emergent relationship between effort and results (eg unknown tipping points) 25
(7) Unintended outcomes Simple Complicated Unintended outcomes can be anticipated and monitored Different unintended outcomes are likely in particular combinations of circumstances expertise is needed to anticipate them and identify them Complex Unintended outcomes cannot be anticipated but only identified (and addressed) as they emerge or in retrospect Funnell and Rogers 2010 Purposeful Program Theory. Jossey-Bass) Funnell and Rogers Purposeful Program Theory 26
Some thoughts on how program theory might address complicated and complex aspects Issues that may need to be addressed 1. Focus 2. Governance 3. Consistency 4. Necessariness 5. Sufficiency 6. Change trajectory 7. Unintended outcomes Possible evaluation methods, approaches and methodologies Emergent evaluation design that can accommodate emergent program objectives and emergent evaluation issues Collaborative evaluation across different stakeholders and organisations Non-experimental approaches to causal attribution/contribution that don t rely on a standardized treatment Realist evaluation that pays attention to the contexts in which causal mechanisms operate Realist synthesis that can integrate diverse evidence (including credible single case studies) in different contexts Butterfly nets to catch unanticipated results Funnell and Rogers Purposeful Program Theory 27
