Abstract: In many projects, the start and finish of activities occurs later than the as-planned timing, while at the same time, the forecasted completion date does not change. This schedule compression can cause significant problems towards the end of the project as an excessive proportion of activities become critical or near critical, placing an unrealistic demand on resources. This paper discusses several tools that can be used as early indicators of schedule compression on the project. The milestone wave chart presents forecast tracking of multiple milestones over the life of the project to reflect work slippage. The float consumption tracking chart indicates how average float values are trending versus the original baseline curve. The % activities near critical chart tracks how many activities are within a certain range of the critical path. These tools can help the project team identify schedule compression early and manage it to minimize problems as the project progresses.
