To achieve objectives of the study, the researcher adopted both Primary and Secondary data sources. Quantitative and Qualitative research approaches; Explanatory and Exploratory research design was also applied. Target population of the study were 49 employees of the organisation who took a role in implementation of the programme. Purposive sampling technique was used to identify the organisation and census is applied for data collection. While the quantitative data was analysed using descriptive, correlation and regression analysis by SPSS version 26.0, the qualitative data was analysed, described, and interpreted in the form of statement. Major findings of the study revealed that there is good project monitoring and evaluation practice in the organization, yet relatively there is weak performance of time. Results also revealed that Pearson correlation between engagement of stakeholders, Capacity management of stakeholders and M&E practice of an organisation were strongly positive with organisation performance. Regression results show that among the factors of organisation performance, monitoring and evaluation practice has relatively the highest influence on organisation performance. This means, the practice of monitoring and evaluation with a high level of effectiveness yields a higher level of organisation performance. To be more successful in organisation performance, the study recommends that the organization must focus on fully enhancing monitoring and evaluation practice and give special emphasis to accomplishing activities on time.
