Principles-Focused Evaluation The GUIDE

How can programs and organizations ensure they are adhering to core principles—and assess whether doing so is yielding desired results? From evaluation pioneer Michael Quinn Patton, this book introduces the principles-focused evaluation (P-FE) approach and demonstrates its relevance and application in a range of settings.

  • (G) (meaningful) guidance
  • (U) useful
  • (I) inspiring
  • (D) developmentally adaptable
  • (E) evaluable

​​There are also a number of helpful features such as rubrics, a P-FE checklist, firsthand reflections and examples from experienced P-FE practitioners, sidebars and summary tables, and end-of-chapter application exercises.

Who is this resource useful for?

• Advocates for evaluation

• Commissioners/managers of evaluation
• Evaluators
• Those involved in evaluation capacity strengthening

How have you used or intend on using this resource?

I am planning to use this to plan evaluations of complex interventions which need to be adaptive and responsive but also organized around some clear ways of navigating decisions, actions and evaluation.  So far I have particularly appreciated its clear analysis of what a good principle looks like, and how to edit existing statements into clear principles. 
Why would you recommend it to other people?

Many people are developing principles to guide their work but have little support to do so, and often end up producing statements that are something else, such as a goal, or a statement about how they think things work rather than an actual principles.  A principle provides a prescription about what to do, although not as a tightly stated rule.  For example, “add a teaspoon of salt” is a rule, whereas “season to taste” is a principle which recognises that this will be operationalised in different ways to suit the context.

The book provides many, many tables, lists, examples and checklists to support people to develop and use principles in planning and evaluating complex interventions. It draws on extensive experience in evaluation, not only from the author but also from a number of other evaluators who provide diverse, detailed exemplars.
