As a program manager, you decided to overlap two phases of your program.

 Fast tracking is a schedule compression technique that involves overlapping two or more phases or activities of a program that are normally performed in sequence. Fast tracking is used to shorten the overall duration of a program without changing its scope or reducing its quality. Fast tracking can increase the risk of rework, errors, or conflicts due to the concurrent execution of interdependent phases or activities12. Lead time is the amount of time between the start or finish of one activity and the start or finish of another activity that is dependent on it. Lead time is used to create a logical or sequential relationship between two activities, such as a finish-to-start, start-to-start, finish-to-finish, or start-to-finish relationship. Lead time can be positive or negative, depending on whether the successor activity starts or finishes before or after the predecessor activity13. Rolling is a planning technique that involves progressively elaborating the details of a program as more information becomes available. Rolling is used to cope with the uncertainty and complexity of a program, and to adapt to the changes and feedback that occur during the program lifecycle. Rolling can be applied to different aspects of a program, such as the scope, schedule, cost, quality, or risk14. Crashing is a schedule compression technique that involves adding or reallocating resources to critical or near-critical activities of a program that are on the critical path. Crashing is used to shorten the overall duration of a program without changing its scope or compromising its quality. Crashing can increase the cost, complexity, or risk of a program due to the additional or redistributed resources15. References:
