Quality Management (QM) is known to help organizations improve their service delivery to realize the effects on output. Clear strategies developed can enable the organization to continuously improve everything under their influence, both services and products.

This study targeted eight hundred and twenty (820) infrastructural projects planned as per the County Integrated Development plan 2018-2022. This research used non-probabilistic sampling. The purposive sampling technique was most appropriate during data collection from identified respondents who were directly assigned and were daily involved with infrastructural projects. The County Integrated Development Plan (CIDP) contains the list of prioritized projects and thus provides the desired study list
