Task 1002 cannot start until how long after Task 1001 finishes?

Task 1002 cannot start until how long after Task 1001 finishes?

• A. 20 days after 1001 finishes.
• B. 10 days after 1001 finishes.
• C. 0 days after 1001 finishes.
• D. 2 days after 1001 finishes.

Answer: (B)

Understanding lag time between tasks. In scheduling, a finish-to-start relationship can include a lag, which is a delay between when one task finishes and when the next begins. If Task 1002 cannot start until after a ten-day waiting period following Task 1001 finishing, 1002 will start ten days later than 1001 ends. For example, if 1001 finishes on day 5, 1002 would start on day 15. This lag accounts for prerequisites, resource readying, or other transitional needs. Zero-day lag would mean an immediate start, a shorter lag would reduce the delay, and a longer lag would push the start further out. Therefore, the required start delay is ten days after Task 1001 finishes.
