Final answer:
The project manager is using a PMIS to resolve resource overallocation through resource leveling or smoothing, inadvertently extending the project schedule.
Step-by-step explanation:
The project manager in question is using a Project Management Information System (PMIS) to manage the resource allocation for project activities. When he notices that resources are double-booked, he utilizes a feature within the PMIS to automatically reschedule activities to resolve resource conflicts. By clicking a button, the software likely uses a resource leveling or resource smoothing algorithm, which prioritizes critical activities and pushes out non-critical ones, hence, extending the overall project schedule. This ensures that resources are not overstretched, but it can result in an increased duration for the project completion.
Step-by-step explanation:
The project manager is using a PMIS (Project Management Information System) to assign resources to activities. However, some resources are double-booked, which means they are assigned to multiple activities at the same time. To resolve this issue, the project manager clicks a button that automatically moves some activities later in the schedule.
By moving activities, the project manager ensures that the double-booked resources are available when needed, avoiding conflicts. However, this adjustment causes the overall schedule to become longer, as activities are now scheduled for later dates.
This approach helps to optimize resource allocation and avoid resource conflicts, but it may result in a longer project duration.
