2. 2 Workshop Objectives Understand the need to address attribution
Understand how contribution analysis can help
Have enough information to undertake a contribution analysis on your own
3. 3 Outline Dealing with attribution
Contribution analysis
Working a case
Levels of contribution analysis
Conclusions
4. 4 The challenge Attribution for outcomes always a challenge
Strong evaluations (such as RCTs) not always available or possible
A credible performance story needs to address attribution
Sensible accountability needs to address attribution
Complexity significantly complicates the issue
What can be done? Recent example of a non-experimental situation mentioned on the internet was evaluations of the Tsunami aid that are being solicited, for example, by UNICEF.Recent example of a non-experimental situation mentioned on the internet was evaluations of the Tsunami aid that are being solicited, for example, by UNICEF.
5. 5 The idea Based on the theory of change of the program,
Buttressed by evidence validating the theory of change,
Reinforced by examination of other influencing factors,
Contribution analysis builds a reasonably credible case about the difference the program is making
6. 6 The typical context A program has been funded to achieve intended results
The results have occurred, perhaps more or less
It is recognized that several factors likely ‘caused’ the results
Need to know what was the program’s role in this
7. 7 Two measurement problems Measuring outcomes
Linking outcomes to actions (activities and outputs), i.e. attribution
Are we making a difference with our actions?
8. 8 Attribution Outcomes not controlled; are always other factors at play
Conclusive causal links don’t exist
Are trying to understand better the influence you are having on intended outcomes
Need to understand the theory of the program, to establish plausible association
Something like contribution analysis can help This is what practical attribution is all about.This is what practical attribution is all about.
9. 9 The need to say something Many evaluations and most public reporting are silent on attribution
Credibility greatly weakened as a result
In evaluations, in performance reporting and in accountability, something be said about attribution
10. 10 Proving Causality The gold standard debate (RCTs et al)
Intense debate underway, especially in development impact evaluation
Some challenge on RCTs (e.g. Scriven)
Does appear if RCTs have limited applicability
Then what do we do?
Need to know better when we can use RCTs: what circumstances, what settings?
Need to know better when we can use RCTs: what circumstances, what settings?
11. 11 Proving Causality AEA and EES: many methods capable of demonstrating scientific rigour
Methodological appropriateness for given evaluation questions
Causal analysis: auto mechanic, air crashes, forensic work, doctors—Scriven’s Modus Operandi approach Always other factors at play
Conclusive causal inks don’t exist
Are trying to understand better the influence you are having on intended outcomes
Plausible association

12. 12 Theory-based evaluation Reconstructing the theory of the program
Assess/test the credibility of the micro-steps in the theory (links in the results chain)
Developing & confirming the results achieved by the program I am building here on the increasingly used theory-based approaches to evaluation.I am building here on the increasingly used theory-based approaches to evaluation.
13. 13 Contribution analysis: the theory There is a postulated theory of change
The activities of the program were implemented
The theory of change is supported by evidence
Other influencing factors have been assessed & accounted for
Therefore
The program very likely made a contribution 1. There is a reasoned postulated theory of change for the program. It makes sense, it is plausible, and is agreed by at least some of the key players. If there is no ToC, experiment!
2. The activities of the program were implemented.
3. The theory of change—or key elements thereof— is supported by and confirmed by evidence, both of experts and of facts: the chain of expected results occurred.
4. Other influencing factors have been assessed and either shown not to have made a significant contribution, or their relative role in contributing to the desired result has been recognized.
Then can say with some confidence that the program has indeed contributed to the observed desired results.

14. 14 Steps in Contribution Analysis 1. Set out the attribution problem to be addressed
2. Develop the postulated theory of change
3. Gather the existing evidence on the ToC
4. Assemble & assess the contribution story
5. Seek out additional evidence
6. Revise & strengthen the contribution story
7. Develop the complex contribution story I set out here the basic steps in a CA. The process is iterative and best developed over time.

15. 15 1. Set out the attribution problem Acknowledge the need to address attribution
Scope the attribution problem
What is really being asked
What level of confidence is needed?
Explore the contribution expected
What are the other influencing factors?
How plausible is a contribution?
16. 16 Cause-Effect Questions Traditional attribution questions
Has the program caused the outcome?
How much of the outcome is caused by the program?
Contribution questions
Has the program made a difference?
How much of a difference?
17. 17 Cause-Effect Questions Management questions
Is it reasonable to conclude that the program made a difference?
What conditions are needed to make this type of program succeed?
Why has the program failed?
