Before you start: Understand scope and finish-to-start dependencies.

Try it

A takes 3 days. B (5 days) and C (2 days) follow A. D (4 days) waits for both. What controls completion?

Your reasoning, assumptions and units:

Apply it to your work

Describe a comparable situation. What evidence would you need before using this reasoning to make a decision?

Your example and next check:

Answer and reasoning

A–B–D takes 3 + 5 + 4 = 12 days; A–C–D takes 9. The earliest finish is 12 under the stated assumptions. C has 3 days of total float. Resource limits or different dependencies can change this.
