The Challenges Ahead for
Impact Evaluation Studies in Poland
Using Mixed Methods of Evaluation
for Policy Making Purposes

International Initiative for Impact Evaluation [3ie]

What Is To Be Evaluated?
• Intervention effectiveness - what works?
• Implementation effectiveness – how/why it works?
• Diversity of effectiveness across different groups –
what works for whom and when?
• Experiential effectiveness - users’ views
• Resource effectiveness - at what cost/benefit?
Philip Davies
www.3ieimpact.org
Which translates into:
• Theory Based Evaluation
How is a policy/intervention supposed to work?
• Impact (or summative) evaluation
Does the policy (programme, intervention) work?
• Process (or formative) evaluation
How, why, and under what conditions does the policy
(programme, intervention) work?
• Developmental evaluation
Supporting innovation and adaptation. Providing feedback,
generating learning, supporting direction or affirming changes in
direction in real time. Building the evidence base over time.

The key to the challenges ahead is:

Evaluation: Theory of Change/Logic Model
• How is a policy/programme supposed to work?
• What activities, mechanisms, people have to be in place?
• And in what sequence – what is the causal chain?
• What resources are required – and are available?
• What data are required – and are available?
• Is the policy/programme feasible/achievable?

Types of Research Synthesis
• Statistical Meta-Analyses
(6-18 months)
• Narrative Systematic Reviews (6-12 Months)
• Rapid Evidence Assessments (1-3 Months)
• Evidence Maps and Gap Maps (1 Month)
• Meta-Ethnography /Qualitative Synthesis (6-12 Months)

Economic Appraisal
No policy programme or project should be adopted
without first having the answer to these questions:
• Are there better ways to achieve this objective
[Cost-Effectiveness Analysis]
• Are there better uses for these resources?
[Cost-Benefit Analysis]
