Precedence

1.No other tasks can start until preliminary design is completed.

2.When preliminary design (A) is completed, final design (B), preparation of assembly and test requirements (C), and parts procurement (D) can start.

3.Assembly (E) cannot start until parts are procured (D), final design (B) is complete, and assembly and test requirements (C) are completed.

4.Procurement of test equipment (F) and preparation of test procedures (G) cannot start until requirements for assembly and test (C) are available.

5.Preparation of test fixtures (H) cannot start until test procedures (G) are available.

6.Testing (I) cannot start until assembly (E) is complete, test equipment (F) has been procured, and test fixtures (H) are available.

SUPPLEMENTAL QUESTIONS

What becomes the critical path if 'Procure Test Equipment' (Task 'F') duration is increased to 20 weeks?

Based on the modified CPM network from the first question (Task F is 20 weeks), what becomes the critical path if 'Prepare assembly and test requirements' (Task 'C') duration is increased to 8 weeks?

What activities would you consider to be risky and why?
