Schedule Compression Techniques

Correct Answer: Hybrid compression-overlap technique

The Hybrid compression-overlap technique is the optimal solution for schedule re-sequencing because: 1. It combines both duration compression methods and parallel execution strategies: - Allows for activity compression when feasible - Enables concurrent execution where dependencies permit 2. Maintains logical dependencies while optimizing the schedule: - Preserves critical relationships between activities - Ensures technical and resource constraints are respected 3. Provides flexibility in implementation: - Can be adjusted based on resource availability - Allows for varying degrees of compression and overlap Why other approaches are less effective: - Concurrent activity optimization with extended resource allocation focuses too heavily on resource distribution rather than balanced schedule optimization - Progressive elaboration through resource leveling emphasizes sequential processing, limiting parallel execution opportunities - Activity splitting with milestone preservation primarily focuses on breaking down activities rather than optimizing the overall schedule flow

Correct Answer: Redistributing resource assignments to maintain optimal project flow while meeting deadlines

The key purpose of schedule re-sequencing when addressing resource overallocation focuses on redistributing resource assignments to maintain optimal project flow while meeting deadlines. This is the most accurate and concise description of the process. Here's why this is the best answer and why others are incorrect: - The correct answer captures the essential elements of schedule re-sequencing: redistribution of resources and maintaining project flow, all while ensuring deadlines are met. - The second option, while similar, adds unnecessary complexity about cost minimization through advanced allocation techniques, which goes beyond the core purpose of schedule re-sequencing. - The third option incorrectly focuses on reducing critical path task durations, which is more related to schedule compression than resource overallocation. - The fourth option incorrectly emphasizes parallel execution methods and schedule compression, which are different techniques from schedule re-sequencing. Schedule re-sequencing primarily aims to resolve resource conflicts by adjusting the timing and sequence of activities while keeping the project's objectives intact. The focus is on finding the most efficient way to use available resources across the project timeline.

Correct Answer: The impact on total float and project completion date

When applying a leveling delay in schedule re-sequencing, the primary consideration should be the impact on total float and project completion date. This is the most critical factor because: Total float affects the flexibility of activities and the overall project schedule Changes to project completion date can impact stakeholder expectations and contractual obligations It helps maintain the integrity of the critical path The other options are incorrect because: Allocating additional resources contradicts the purpose of resource leveling, which aims to work with existing resource constraints Reducing activity durations through productivity measures is a different technique (resource optimization) and not the primary consideration in leveling delays Applying mandatory dependencies focuses on logical relationships rather than resource constraints, and may actually create additional scheduling problems
