Abstract: “The estimates of the number of resources required in a software development project is an important part of the project planning stage. Estimates are activities that predict the output of a project by reviewing existing resources such as time, cost, risks to be faced, and the effort required to complete the project. Methods such as Use Case Points (UCP), which are based on the number of actors and use case complexity are popular as methods for estimating effort in software development projects. However, the weight calculation for the Unadjusted Use Case Weight (UUCW) as part of the UCP still has something called “not mathematically valid operations.” Therefore, it takes an alternative way to calculate the weight of the UUCW. In this study, we implement a linear equation to determine the UUCW. The linear equation is derived from the value of the weight of UUCW on UCP original (UCP proposed by Karner). A linear line is created in which the x-axis is the center point of the transaction am”
