CST Milestone & Constraint Management 3

Question 1

A milestone representing 'System Integration Complete' has no successors in the schedule. What scheduling problem does this represent?

Accepted Answer

Dangling finish

Answer

A milestone or activity with no successors creates a dangling finish, which violates sound CPM scheduling practice.

Question 2

Which constraint should be used when a task can begin no earlier than the receipt of a government permit expected on a fixed date?

Accepted Answer

Start No Earlier Than (SNET)

Answer

SNET is a soft constraint that prevents a task from starting before a specified date, appropriate for externally-driven early boundaries.

Question 3

In Earned Value Management, which milestone-related metric measures schedule efficiency at a point in time?

Accepted Answer

Schedule Performance Index (SPI)

Answer

SPI (EV/PV) measures how efficiently the project is progressing against the planned schedule, including milestone achievement.

Question 4

A scheduler is told a client milestone cannot move. After network analysis, the milestone shows -10 days of float. What is the BEST corrective action?

Accepted Answer

Add resources or overlap tasks to recover 10 days on the driving path

Answer

The correct response to negative float on a hard-date milestone is to compress the driving path through crashing, fast-tracking, or added resources.

Question 5

Which term describes a milestone that is linked to payment authorization upon verified completion?

Accepted Answer

Contract milestone

Answer

A contract milestone triggers a financial event such as payment or billing upon verified achievement, making it legally and commercially significant.
