Defining statistical distribution for remaining duration

  1. Select the task to which you want to enter the tracking data.
  2. Open the Task Information dialog box.
  3. Click the Tracking tab. By default, the first row should contain the actual start time with zero percent done.
  4. Enter low, base and high remaining duration for certain status date
  5. Right click on ID and select Distribution for remaining duration
  6. Select the distribution from the Distribution list. If you select Undefined, remaining duration will not be used for probabilistic analysis (analysis will be done using percent completed only) .
  7. Define the distribution parameters. The Probability Density chart is automatically updated. You can adjust distribution parameters using the sliders.
  8. If you use a custom or discrete distribution, a grid opens. The grid will allow you to define points (or intervals for discrete distributions) and associated with each point (interval)
  9. Normal or Lognormal, you must select the Low and High probability range (P1 and P99, P5 and P95 or P10 and P90). These are "cut-off" parameters; meaning that duration, cost, or start time cannot go beyond these values.
