Which scheduling concept describes the amount of time a non-critical activity can be delayed without delaying the early start of any successor activity?
Answer: Free float
Free float is the amount of time an activity can slip without delaying the early start of its immediate successor(s).
In schedule compression, crashing is most effective when applied to activities that have:
Answer: The lowest cost slope (least cost to shorten per unit of time)
Crashing prioritizes critical path activities with the lowest cost slope — the least additional cost per unit of schedule reduction.
A project's original schedule showed 100 days duration. After a scope increase and approved change, the revised baseline shows 115 days. What is the schedule variance if EV work equals 60 days and PV equals 70 days of planned work?
Answer: -10 days
SV = EV - PV = 60 - 70 = -10, indicating the project has accomplished 10 days less work than planned at this point.
Which type of schedule is typically used in construction projects to show the planned production rate for repetitive activities across multiple floors or units?
Answer: Linear scheduling method (LSM) / Line of Balance
Linear Scheduling Method (also called Line of Balance) graphically shows production rates and resource continuity for repetitive construction work.
What is the primary risk associated with aggressive fast-tracking of a project schedule?
Answer: Increased rework risk due to overlapping activities that may have unresolved dependencies
Fast-tracking increases the risk of rework because starting downstream activities before upstream work is complete can cause conflicts when changes are needed.
Which document provides the authorized time-phased budget for the project and is used as the baseline for measuring schedule and cost performance?
Answer: Performance measurement baseline (PMB)
The Performance Measurement Baseline integrates scope, schedule, and cost baselines and is used to measure and manage project performance.
When a project schedule shows negative float on the critical path, this indicates:
Answer: The project cannot meet its imposed finish date without corrective action
Negative float means the calculated project finish date exceeds the target finish date, requiring schedule compression or scope/resource changes.
