Senior Project Officer Question:

When the activity effort and resource estimates are known getting the work done depends on how the tasks are sequenced. Dependencies with other activities have to be clearly known. The basic sequence is determined by what activities should be carried out first and what should follow. Unconnected tasks/activities can be sequenced in parallel to reduce project time. Most optimized sequencing would give you the best possible time needed given the resources allocation is ideal and there are no constraints there. Scheduling is done from activities list prepared after WBS has been finalized.
