Dates and Durations tab - Check Schedule dialog box
Use the Check Schedule dialog box, Dates and Durations tab to specify settings to use for analyzing float, large durations, out-of-progress activities, late activities, and the how the current completion state of the schedule compares to the expected completion according to the baseline.
Large Float - Activities with total float greater than: Mark to analyze the percentage of activities calculated by the scheduler to have a float duration greater than the value you specify. Completed, WBS Summary, and Level of Effort activities are not included in this analysis. Specify the target for the acceptable percentage of activities that can have a float duration over the value you specify.
Negative Float - Activities with a total float less than 0: Mark to analyze the percentage of activities calculated by the scheduler to have a float duration of less than zero. These activities are likely to delay the end date of the project if corrective action is not taken. Completed, WBS Summary, and Level of Effort activities are not included in this analysis. Specify the target for the acceptable percentage of activities that can have negative float.
Large Durations - Activities that have a remaining duration greater than: Mark to analyze the percentage of activities that have a remaining duration greater than the value you specify. Completed activities, WBS Summary activities, and Level of Effort activities are not included in this analysis. Specify the target for the acceptable percentage of activities that can have a large remaining duration.
Activities with invalid progress dates: Mark to analyze the percentage of activities with invalid dates. Invalid dates for not started activities are start dates earlier than the data date. Invalid dates for in progress activities are remaining early start dates earlier than the data date or actual start dates later than the data date. Invalid dates for completed activities are actual finish dates later than the data date. Completed activities with an actual finish earlier than the data date, WBS summary activities, and Level of Effort activities are not included in this analysis. Specify the target for the acceptable percentage of activities that can have invalid progress dates.
Late Activities - Activities scheduled to finish later than the project baseline: Mark to analyze the percentage of activities that are scheduled to finish later than the corresponding activity in the project baseline. If an activity has no corresponding activity in the project baseline, it is considered to fail this test if its remaining early finish date is later than its planned finish date. Milestones, WBS Summary activities, and Level of Effort activities are not included in this analysis. Specify the target for the acceptable percentage of activities that can be scheduled to finish later than their baseline finish date or have no corresponding baseline activity.
BEI - Baseline Execution Index: Mark to analyze the number of completed activities in the project against the number of baseline activities calculated to finish before the open project's data date. Not started activities, in progress activities, Milestones, WBS Summary activities, and Level of Effort activities in the open project are not included in this analysis. In the project baseline, milestones, WBS Summary activities, Level of Effort activities, and activities with a finish date later than the open project's data date are not included in this analysis. Specify the target for the acceptable ratio of completed activities in the open project compared with baseline activities scheduled to finish before the open project's current data date, as expressed as a percentage.
