Describe the purpose of schedule compression techniques.
Schedule compression techniques are employed in project management to accelerate the completion of a project without compromising its quality or scope. These techniques are applied when there is a need to meet tight deadlines, overcome delays, or address unexpected issues that may arise during the project execution. The primary goal of schedule compression is to reduce the project duration while minimizing the impact on project objectives. There are two main types of schedule compression techniques: crashing and fast tracking.
- Crashing:
- Definition: Crashing involves allocating additional resources to critical path activities to reduce their duration.
- Technical Details:
- Resource Allocation: Identify critical path activities (those with zero or negative float) and allocate additional resources such as manpower, equipment, or technology to these tasks.
- Resource Leveling: Ensure that the added resources are efficiently utilized without causing overallocation or burnout. Resource leveling helps in smoothing out resource demand over the project timeline.
- Cost-Benefit Analysis: Evaluate the cost implications of crashing activities. Determine if the cost of additional resources justifies the time savings and aligns with project constraints.
- Fast Tracking:
- Definition: Fast tracking involves overlapping or running activities in parallel that are normally performed in sequence to shorten the project duration.
- Technical Details:
- Identifying Dependencies: Carefully review task dependencies to identify opportunities for parallel execution. Tasks that are dependent on each other may need to be re-evaluated to determine if they can be performed concurrently.
- Risk Assessment: Assess the potential risks associated with fast tracking, such as increased likelihood of rework or miscommunication due to parallel activities.
- Communication and Coordination: Enhance communication and coordination among project team members to ensure that overlapping activities are executed smoothly without compromising quality.
- Overlap of Phases:
- Definition: Overlapping phases involves initiating the next phase before the completion of the previous one.
- Technical Details:
- Interphase Dependencies: Carefully analyze dependencies between project phases to identify opportunities for overlap. Ensure that starting the next phase early does not compromise the quality or completeness of the preceding phase.
- Feedback Mechanisms: Establish effective feedback mechanisms to monitor the progress of overlapping phases and address any issues promptly.
- Critical Chain Method (CCM):
- Definition: Critical Chain Method focuses on identifying and managing the project's critical chain, which is the longest sequence of dependent and resource-constrained tasks.
- Technical Details:
- Buffer Management: Introduce project buffers strategically to accommodate uncertainties and delays without affecting the overall project timeline. Buffer management helps protect the project completion date by incorporating buffers at critical points in the schedule.
- Resource Management: Identify and manage resource constraints, ensuring that critical resources are efficiently allocated to activities along the critical chain.
