Resource Scheduling

Correct Answer: Resource Leveling

The best answer to this question is 'Resource Leveling.' A key component of resource leveling is adjusting the schedule based on resource constraints, which is the situation described in the question. The resource leveling technique helps to effectively manage the resources available for a limited period of the day. The 'Critical Path Method' does not directly deal with resource scheduling; it is a scheduling technique used to identify the longest path in a schedule, which provides the shortest possible project duration. The 'Precedence Diagramming Method' is a tool for scheduling activities in a project but does not take into account specific resource limitations. Lastly, 'Monte Carlo Simulations' is a risk analysis technique, not a scheduling technique, and would not help in managing a highly skilled resource with limited availability.

Correct Answer: Resource Smoothing

Resource Smoothing is the best scheduling technique for handling fluctuating resource requirements. This technique involves adjusting the non-critical tasks within their float, i.e., the allowable slippage before it would affect the project timeline, to smooth out the resource requirement peaks and troughs. This ensures an efficient and balanced utilization of resources. The other options provide alternative techniques but they do not offer the same flexibility to handle fluctuating resource requirements. Program Evaluation and Review Technique is used for complex projects where time and cost estimates are uncertain. Critical Path Method is used to schedule project activities to reduce slack time and accelerate project completion. What-if Scenario Analysis is used to assess the feasibility of the project under different scenarios, not for rescheduling resources.

Correct Answer: Resource Leveling

Resource Leveling is the most appropriate scheduling technique to use when a key resource suddenly leaves the team. This technique is used to adjust the project schedule and is triggered by resource limitations (usually human resources). It aims to balance the demand for resources with the available supply and is often used when the resources are over-allocated. On the other hand, Monte Carlo Analysis is a risk analysis technique used to understand the impact of risk and uncertainty in project management and cost estimation, and it's not directly related to resource allocation or scheduling. The Critical Path Method is used for scheduling activities in a project but doesn't specifically deal with resource allocation issues. What-if Scenario Analysis is also a risk assessment technique used to explore the outcomes of different project paths, and it's not related to the direct reorganization of resources.
