in an open and inclusive manner in order to achieve buy-in from the various stakeholder groups. In this case, the working group method is the preferred mode for evaluators to facilitate stakeholders in developing the program theory.

Group members need to include those who are deeply involved in designing the program and other key constituencies whose input will be influential as to the direction the program will take. Evaluators serve the role of facilitator in the meeting.
