Abstract: The present invention is a project management tool uniquely suited to define and develop significant system events that can be effectively used as system test points to measure the performance and determine whether the system under design is meeting key design requirements. This methodology utilizes Synch Points in a state diagram to provide a directed graph notation and to generate a system timeline execution model automatically. The state diagram provides an improved means to decompose system event times into mechanical motion times, move transition latency times, and application software latency times. The system timeline execution model data is fed into a simulation engine to verify that the system timeline execution model is executable and confirms the dependencies are complete and accurate.
