Evaluation Phases and Processes
This Chapter [PDF – 777 KB] The program evaluation process goes through four phases — planning, implementation, completion, and dissemination and reporting — that complement the phases of program development and implementation. Each phase has unique issues, methods, and procedures. In this section, each of the four phases is

Building from previous frameworks, the authors present a comprehensive and systematic approach for developing a process-evaluation plan to assess the implementation of a targeted health promotion intervention. Suggested elements for process-evaluation plans include fidelity, dose (delivered and received), reach, recruitment, and context.
