The scheduling sequence

(ioing from an ideal activity plan to a costcd schedule can be represented as a sequence of steps, rather like the classic waterfall life-cycle model. In the ideal world, we would start with the activity plan and use this as the basis for our risk assessment. The activity plan and risk assessment would provide the basis for our resource allocation and schedule from which we would produce cost schedules.

In practice, as we have seen by looking at Amanda's project, successful resource allocation often necessitates revisions to the activity plan, which, in turn, will affect our risk assessment. Similarly, the cosi schedule might indicate the need or

desirability to reallocate resources or revise activity plans - particularly where that schedule indicates a higher overall project cost than originally anticipated.

The interplay between the plans and schedules is complex - any change to any one will affect each of the others. Some factors can be directly compared in terms of money - the cost of hiring additional staff can be balanced against the costs of delaying the project's end date. Some factors, however, are difficult to express in money terms (the cost of an increased risk, for example) and will include an element of subjectivity.

While good project planning software will assist greatly in demonstrating the consequences of change and keeping the planning synchronized, successful project scheduling is largely dependant upon the skill and experience of the project manager in juggling the many factors involved.
