When changes in the context or object of the evaluation occur, the evaluator must ask whether that change should affect the list of evaluation questions. Does it make some questions moot? Raise new ones? Require revisions? Would changing questions or focus in the middle of the evaluation be fair? The evaluator should discuss any changes and their impact on the evaluation with the sponsor, client, and other stakeholders. Allowing questions and issues to evolve, rather than committing to an evaluation carved in stone, fulfills Stake's (1975b) concept of responsive evaluation discussed in Chapter 8. and such flexibility and responsiveness is advocated by today's participatory approaches (Cousins & Shula, 2008).
