Schedule Monitoring and Control Processes

Correct Answer: Develop a schedule compression strategy and update the risk register

An SPI of 0.85 indicates that the project is behind schedule (performing at 85% of the planned rate), and since this involves a critical path activity, it requires immediate attention. Developing a schedule compression strategy is the most appropriate response because: 1. Critical path activities have zero float and any delay impacts the project end date 2. A schedule compression strategy can help bring the project back on track 3. Updating the risk register helps document and manage the schedule risks Why other options are inadequate: - Adding resources to all activities is wasteful and unnecessary - only the critical path needs attention - Requesting a budget increase does not address the schedule delay issue - Waiting for the next review cycle is inappropriate for critical path delays as they require proactive management The best approach is to focus on the specific critical path activity causing the delay and develop targeted compression strategies like fast tracking or crashing, while documenting the associated risks.

Correct Answer: Schedule Performance Index (SPI)

Schedule Performance Index (SPI) is the most appropriate metric to determine if a project can meet its completion date because: SPI provides a ratio of earned value to planned value, showing how efficiently the project is using time. An SPI of less than 1.0 indicates the project is behind schedule, while greater than 1.0 shows ahead of schedule. This metric is superior to the alternatives because: CPM float analysis and variance reporting are useful tools but focus more on individual activities rather than providing an overall performance measure of schedule efficiency. Resource Utilization Index with milestone tracking primarily measures resource efficiency and milestone achievement, but does not provide a comprehensive view of schedule performance. EVMS cost variance indicators focus on cost performance rather than schedule performance, making them less relevant for determining schedule completion capability.

Correct Answer: Progressive schedule elaboration with rolling wave planning

Progressive schedule elaboration with rolling wave planning is the most appropriate technique when dealing with multiple changes in activity durations and dependencies. Here's why: Progressive elaboration allows for: - Iterative schedule updates as more information becomes available - Flexibility to accommodate changes in activity durations - Ability to adjust dependencies based on evolving project needs - Gradual refinement of schedule details through rolling wave planning Why other approaches are less suitable: Fast tracking with resource leveling might create additional risks and complexity when the schedule is already experiencing multiple changes. Complete schedule compression could add unnecessary pressure and might not address the root cause of the changing durations and dependencies. Critical chain method, while useful for resource management, may be too rigid when dealing with multiple ongoing changes, as it focuses more on buffer management than accommodating frequent schedule modifications.
