TABLE OF CONTENTS Date slippage occurs when an activity is rescheduled to finish later then originally planned. There are two courses of action available:
The first is to accept the slippage. This is rarely acceptable, but it is the easiest answer.
The second is to examine the schedule and evaluate how you could improve the end date.
Solutions to return the project to its original completion date must be cleared with the person responsible for the project.
Suggested solutions to bring the project back on track include:
Reducing the durations of activities on, or near the critical path. When activities have applied resources, this may include increasing the number of resources working on the activities. Changing longer activities is often more achievable than changing the length of short duration activities.
Changing calendars, say from a five-day to a six-day calendar, so that activities are being worked on for more days per week.
Reducing the project scope and deleting activities.
Changing activity relationships so activities take place concurrently. This may be achieved by introducing negative lags to Finish-to-Start relationships, which maintain a Closed Network. A negative lag will allow the successor activity to start before the predecessor is complete, which is often what happens in reality.
Replacing Finish-to-Start relationships with Start-to-Start relationships. Activities are now progressing in parallel and therefore at the same time. This has the potential of creating an open network as the predecessor activity may no longer have a finish date successor and an extension in the duration...
