How to Track Schedule Performance with Activity Slip and Gain

Complete workflow guide for schedule performance tracking in construction project management

Activity Slip and Gain helps you monitor how project activities perform against baseline dates and quickly identify which tasks contribute to program delays. Use this feature to spot schedule variances early and manage timeline risks proactively.

Steps

Set up Baseline Completion Date

  1. Navigate to the Project Schedule section in your project
  2. Select the activities you want to baseline by checking the boxes
  3. Click Set Baseline Completion Date and confirm the baseline dates for each selected activity
  4. Click Save to establish your baseline

Baseline dates establish the foundation for tracking schedule performance.

Update Planned/ Actual Completion Date

  1. Select an activity that needs a date update by clicking on the activity row
  2. Enter the new Planned/Actual Completion Date based on current information from your team
  3. Click Save Changes to update
  4. Repeat for all activities with updated timelines

As you receive updates from consultants and contractors, regularly update the forecast dates.

Monitor slip and gain indicators

  1. Navigate to the Schedule Worm Chart within your project schedule
  2. Review the visual indicators for each activity:
    • Red indicators: Activities slipping behind baseline (slip)
    • Green indicators: Activities ahead of baseline (gain)
  3. Note the values showing days ahead or behind schedule

Troubleshooting

  • Problem: No slip/gain indicators showing. Solution: Verify baseline dates are set, and forecast dates are different from baseline dates
