Schedule Re-sequencing

Correct Answer: To perform activities in parallel that would normally be done in sequence

Fast-tracking is a schedule compression technique where activities that would normally be done in sequence are performed in parallel. This is achieved by overlapping activities that would typically be done one after another, which helps reduce the overall project duration. It's important to note that fast-tracking may increase risks and require additional coordination. Adding more resources is actually crashing, not fast-tracking. Reducing total float of non-critical activities doesn't compress the schedule since these activities already have slack time. Performing activities sequentially is the opposite of fast-tracking's purpose, which aims to parallelize activities.

Correct Answer: Adding resources to critical activities to reduce duration while increasing cost

Project schedule crashing is a specific schedule compression technique where additional resources are added to critical path activities to reduce their duration, though at increased cost. This is the correct definition because: - It focuses on critical path activities - It involves adding resources - It acknowledges the trade-off between time and cost - It maintains project quality standards The other options are incorrect because: - Reducing quality standards is not schedule crashing - this compromises project deliverables and is not an accepted practice - Extending the timeline with buffer time is the opposite of schedule compression - Modifying project scope to reduce deliverables changes the project's fundamental objectives rather than optimizing the schedule Schedule crashing is specifically about the time-cost trade-off, where spending more money on resources can help shorten the project duration while maintaining the same scope and quality.

Correct Answer: Fast tracking parallel activities while maintaining logical dependencies

Fast tracking parallel activities while maintaining logical dependencies is the most effective technique for schedule re-sequencing. This approach optimizes the timeline by overlapping activities where possible, while preserving essential relationships between tasks. This method is superior because: - It maintains project logic and dependencies - Allows for parallel execution where feasible - Reduces overall duration through smart sequencing - Balances efficiency with risk management The other options are problematic: - Compressing all activities by adding resources can lead to diminishing returns and increased costs - Extending non-critical activities can unnecessarily delay the project and waste resources - Converting all finish-to-start relationships to start-to-start is too aggressive and risky, potentially compromising project quality and logical sequences
