There are two reasonable ways to shut down the project model. One is simply to stop simulating when the project is done. You can do this by writing a different equation for FINAL TIME. The approach we will take here is to stop activity on project completion. We add in the concept project is done and make a connection from that to work flow.
The dependence of project is done on Work Accomplished rather than Work Remaining will provide us with a mechanism for descoping the project if there are schedule or budget problems. We add the equations:
project is done = IF THEN ELSE(Work Accomplished >=
initial project definition,1,0)
Units: Dmnl
work flow = IF THEN ELSE(project is done,0,100)
Units: Drawing/Month
This yields the results:
Finished on time, and on budget. A project manager's dream, and the basic model used in most project management software.
