Project Slippage is a time length for which a given project postpones the accomplishment of its goal or objective. It is a delay that identifies the project’s inability to follow the schedule baseline because of some reason(s) (e.g. poor scheduling, lack of control).
Project slippage or delaying is a kind of project variation that shows there is a delay between the planned start time and actual start time of project activities. If there is slippage in a project, then the planning process appears to be ineffective. It means that the project plan does not support the real situation the project is involved in.
Poor project planning entails the following problems that heighten slippage:
- Inappropriate resource allocation
- Lack of control over project activities
- Broken deadlines
- Later delivery
- Unmet goals
- Unsatisfied stakeholders
Project slippage can be prevented by careful planning that ensures appropriate execution, monitoring, and control of project effort. The following actions may be useful in this regard:
- Evaluate the risk of slippage and have a corrective action plan
- Define time requirements carefully at the very beginning
- Commit the team to doing the project on schedule
- Motivate vendors and suppliers to ensure timely deliveries.
