Negative Float (DCMA Point 7 - "Negative Float" Assessment)
SSI Tools Counts:
Incomplete Tasks (not summaries and not zero duration milestones) with a Total Slack value less than 0 days. The Pass threshold is no more than 0% of the task counted in the population.
An incomplete task with total float less than 0 working days is included in this metric. It helps identify tasks that are delaying completion of one or more milestones. Tasks with negative float should have an explanation and a corrective action plan to mitigate the negative float. Divide the total number of tasks with negative float by the number of incomplete tasks. Ideally, there should not be any negative float in the schedule.
