• The purpose of project evaluation is to assess
performance, reveal areas where the project is not
achieving goals, and uncover extant or potential
problems so they can be corrected.
• Although it is certain that problems and deviations will
occur, it is not known a priori where or when.
• Evaluation for the purpose of guiding the project is called
formative evaluation.
• It addresses the questions:
1) What is happening?
2) How is the project proceeding?
• Evaluation for the purposes of appraising the project
after it is completed and assessing the end results is
called summary evaluation.
