Abstract Fast-growing software needs result in the rise of quality software in technical and time challenges in software development and the impact the cost and scarcity of resources addressed by the companies. Thus, this research focuses on optimal implementation of the User Acceptance Testing (UAT) and the process generation integration. The Software Development Life Cycle (SDLC) was adapted to develop software and introduce the UAT process right from the initial phase of the software development. Additionally, it is devised to maximise time reduction by implementing the client testing in all the three processes. A High Capability to Detect (HCD) procedure has been incorporated in the problem formulation that has optimally identified sensitive bugs. A Modified Reuse of Code (MRC) is proposed for a feasible time-saving solution. The proposed UAT will provide an optimal solution in the software testing phases implemented earlier than black-box testing. The proposed UAT has significantly better production time, development cost, and software quality in comparison to other traditional UATs. The study's findings were corroborated by the output data from the UAT cases. The UAT ensures the quality of the product in the early phase of the development and implementation of the projects. This will minimise the risk during and post-implementation of bugs and achieve the target audience’s needs.
