Designing and implementing a monitoring and evaluation (M&E) system demands discipline, focus, and constant attention to the myriad details that necessarily comprise the M&E activities. Good M&E, if done right, is the backbone of a project. It clarifies the intent of the project, measures progress and success, and supports staff by providing timely and accurate information they can use to better manage their activities. Done poorly, M&E is a burden to all and provides useless information to project staff and donors.
