Adding 3-point Estimates

Adding 3-point estimates for task duration and start times using Task Information Dialog

1. On the Project view, double-click on the task ID.
2. Click the General tab.
3. Define a Base, Low, and High dates for Duration and/or Start Time.
4. Define a Base, Low, and High values for Duration. By default, when you enter a value for duration, the default values for Low and High are calculated based on the defaults set in the Duration Options.
5. Click OK to save the estimates.

Adding 3-point estimates for task duration using the Project View

1. On the Project view, select the task to which you want to add cost and income estimates.
2. Enter cost data for Duration Low, Duration Base, and Duration High. By default, when you enter a value for Duration Base, the default values for Low and High are calculated based on the Duration defaults set in the Duration Tab of Project Options dialog.
3. You may define a Most Likely Duration. The Duration Most Likely column is hidden by default, so you will need to insert the to your datasheet. To insert column right click on column header, choose 'Insert Column Before...' or 'Insert Column After...', and select Duration Most likely.

Adding 3-point estimates for task cost and income

1. On the Cost and Income view, select the task to which you want to add cost and income estimates.
2. Enter cost data for Cost Low, Cost, and Cost High. By default, when you enter a value for Cost, the default values for Low and High are calculated based on the Cost defaults set in the Cost Tab of Project Options dialog.
3. You may define a Most Likely Duration. The Duration Most Likely column is hidden by default, so you will need to insert the to your datasheet. To insert column right click on column header, choose 'Insert Column Before...' or 'Insert Column After...', and select Duration Most likely.

Adding 3-point estimates for lags

1. On the Project view, double-click on the task ID.
2. Click the Predecessor tab.
3. Enter Low, Base, and High Lag. Default statistical distribution will be generated automatically. There are only two distributions for lag: Uniform Triangular.
