Problem: During the planning of a project, managers have different tools that facilitate planning the execution of the activities and give them the ability to control the factors that make up the triple constraint (scope, time and cost). The Curve Budget is a tool utilized to plan, visualize, estimate, and control project costs, and it owes its name to the S shape that it normally draws since in the first periods the project costs are low, and then in the periods of high execution, there is a greater volume of resource application for the completion of activities until the closure of the project, where costs decrease again.
