I am wondering what the typical approach would be here:
In a project, we are renewing old machines and therefore the new ones will need to be integrated into an older system. That might or might not cause problems, and we know the time needed to fix these problems. However, our management requires planning and data, and I struggle with how to reflect the situation:
- If all goes well, the project will take 100 MDs
- If there are problems in all (let's say 10 areas), then the project will take 300 MDs.
Now, if I plan the project for the worst possible scenario, 300 MDs, then - if there is less problems - the progress and effort spent will not really match. Our management looks at % Done and also effort spent.
