The parameters of project success Studies conducted by project management science experts on project success reveal that cost, time, and quality are the three basic and most important indicators of performance in a project. Other parameters such as safety, functionality, and the client's satisfaction have begun to be considered lately. These parameters must be known by the project manager, client, and all stakeholders as a reference for implementing the project. Successful projects are measured in terms of timeliness, cost-efficiency, and optimal quality. In this study, a case was taken in PT. XYZ. However, in the implementation of development, there are often delays in the process, so the impact on the production process is detrimental to the industrial owner. Therefore, it is necessary to accelerate the development in this case of the construction of a feedmill tower with an alternative to the addition of overtime work in 3 ways, namely the addition of 1 hour overtime, 2 hours overtime, and 3 hours overtime. The data used in the analysis of the feed mill development project data with the normal time of the project for 360 days with a normal cost of US$ 5,149,297.20. From the results of the analysis of cost optimization due to the addition of overtime hours to accelerate the implementation, the optimum time to accelerate project completion is added 1 hour of overtime. Crash cost of required US$ 5.178.658,-. The time reduction to complete the project is 330 days. The additional cost is US$ 29.360, and the cost slope is US$ 26.913.
