Unformatted text preview: requires corrective action. For example, a major delay on a noncritical activity may have little effect on the overall project, while a much shorter delay on a critical or near-critical activity may require immediate action. .3 Additional planning. Few projects run exactly according to plan. Prospective changes may require new or revised activity duration estimates, modified activity sequences, or analysis of alternative schedules. .4 Project management software. Project management software is described in Section 18.104.22.168. The ability of project management software to track planned dates versus actual dates and to forecast the effects of schedule changes, real or potential, makes it a useful tool for schedule control. .5 Variance analysis. Performance of the variance analysis during the schedule-monitoring process is a key element for time control. Comparing target dates with the actual/forecast start and finish dates provides useful information for the detection of deviations and for the implementation of corrective solutions in case of delays. The float variance is also an essential planning component to evaluate project time-performance. Particular attention has to be given to critical and subcritical activities (i.e., analyzing the ten subcritical paths, in order of ascending float). 6.5.3 Outputs from Schedule Control .1 Schedule updates. A schedule update is any modification to the schedule information that is used to manage the project. Appropriate stakeholders must be notified as needed. Schedule updates may or may not require adjustments to other aspects of the project plan. Revisions are a special category of schedule updates. Revisions are changes to the schedule start and finish dates in the approved project schedule. These changes are generally incorporated in response to scope changes or changes to estimates. In some cases, schedule delays may be so severe that rebaselining is 80 NAVIGATION LINKS ACROYMNS LIST ACRONYMS LIST ACROYMNS LIST A Guide to the Project Management Body of Knowledge (PMBOK Guide) 2000 Edition 2000 Project Management Institute, Four Campus Boulevard, Newtown Square, PA 19073-3299 USA Chapter 6--Project Time Management needed to provide realistic data to measure performance. However, care must be taken before rebaselining, as historical data will be lost for the project schedule. Rebaselining should only be used as a last resort in controlling the schedule; new target schedules should be the normal mode of schedule revision. .2 Corrective action. Corrective action is anything done to bring expected future schedule performance in line with the project plan. Corrective action in the area of time management often involves expediting: special actions taken to ensure completion of an activity on time or with the least possible delay. Corrective action frequently requires root-cause analysis to identify the cause of the variation, and schedule recovery can be planned and executed for activities delineated later in the sche...
