In MRP, I want the manage the stages in Producing the Product. Once Manufacturing order is in 'Production Started' state, i have to track the varios stages in production.

For Example: To manufacture the the Car, we assume to have following stages

1) Assembly

2) Bodywork

3) Painting

4) Stamping etc...

How to manage these stages in Manufacturing. Once the stages are completed it should be added to stock. Can I customize via Project Management module like following workflow:

Manufacturing Order->Confirm Production->Project Management-> step 1->step  3->Manaufacture Done

So that the Production stages can be managed in Project Management. Is it possible or provide your solution. Please help.
