Schedule Development

Correct Answer: Resource Leveling

In this scenario, resources are overallocated at certain times, leading to potential delays in critical activities. Resource Leveling is the appropriate technique to address resource overallocations by adjusting the schedule based on resource constraints. It involves delaying activities until resources become available, which may affect the critical path and extend the project duration. Given the limited resources and tight deadlines, Resource Leveling helps optimize the schedule by ensuring that resources are not overcommitted, even if it means altering the original timeline. Resource Smoothing is not suitable here because it only adjusts activities within their available float without affecting the critical path or project duration. However, the overallocations are impacting critical activities with little or no float, so Resource Smoothing cannot resolve the issue. Schedule Compression techniques like crashing and fast-tracking aim to shorten the project duration but do not address resource overallocations. Fast Tracking may even increase resource demands and risks by performing tasks in parallel. Therefore, Resource Leveling is the most appropriate technique to optimize the schedule and ensure efficient resource utilization in this scenario.

Correct Answer: Gantt chart

A Gantt chart is the most effective way to display information for an infrastructure project where all tasks are interdependent and a delay in one task will delay the entire project. Gantt charts provide a visual representation of project tasks along a timeline, clearly showing the sequence of activities and their dependencies. This allows project managers to easily identify how delays in one task can impact subsequent tasks and the overall project schedule. Gantt charts also enable tracking of progress and facilitate more accurate schedule management. While other methods like the Precedence Diagramming Method (PDM) can show task dependencies, Gantt charts excel in providing a continuous visual display of the project schedule and progress, making them ideal for monitoring interdependent tasks and their potential impact on the project timeline.

Correct Answer: Critical Path Method (CPM)

The Critical Path Method (CPM) is the technique that involves calculating the early start, early finish, late start, and late finish dates for each activity in a project. CPM is a scheduling technique used to determine the minimum project duration and identify the critical path, which is the longest sequence of activities that must be completed on time for the project to finish by the planned end date. The other options are not specific techniques for calculating the early and late start and finish dates: - Dependency Analysis Technique is a general term for analyzing task dependencies, but does not specifically refer to the CPM calculations. - Network Diagramming Method refers to creating a network diagram to visualize task dependencies, but does not involve the specific CPM calculations. - Task Sequencing Approach is a general term for determining the order of tasks, but does not involve the specific CPM date calculations.
