Abstract: In Makueni County, health projects are a key focus of development, receiving the second-highest number of projects and fifth-highest budget allocation. However, there have been delays in project completion, with 23 projects still ongoing and 23 delayed out of a total of 334 health projects (County Project Management System, 2017). Despite the importance of monitoring and evaluation in ensuring the success of these projects, the monitoring and evaluation process in Makueni is inadequate, with limited research on the influence of monitoring and evaluation functions such as planning, training, and frameworks on health project performance. This lack of emphasis on monitoring and evaluation has led to a potential risk of misusing public or donor funds and an increase in delayed projects or projects not achieving their expected outcomes.
