The best approach to resolve resource over-allocation is through the use of float, also known as slack. Float refers to the amount of time that a task can be delayed without affecting the subsequent tasks or the overall project completion date. When a resource is over-allocated, managing and utilizing float can help adjust the timeline of certain tasks to alleviate pressure on the over-allocated resource.

For instance, if a resource is scheduled to work on multiple tasks simultaneously, identifying and using float in less critical activities allows adjustments to be made, potentially moving tasks that have less immediate deadlines to later dates. This reallocation of time can prevent the resource from being overwhelmed and help maintain project schedules without additional costs or substantial changes.

Looking at the other options, extra labor could resolve over-allocation by increasing resource capacity, but it may involve additional costs and could complicate project management. Time buffers are intended to accommodate unforeseen delays, but they don’t directly address the root of resource over-allocation if the resource's workload is consistently too high. Resource reallocation involves shifting responsibilities among team members or resources, which can be effective but might not be practical if all resources are already at full capacity. Utilizing float is generally a more strategic method for addressing over-allocation while keeping the
