The DCMA 14-point schedule assessment sets a threshold that positive lags (delays inserted between predecessor and successor activities) should appear on no more than 5% of all schedule relationships.
Under AACE International Recommended Practice 18R-97, a Class 5 cost estimate (concept screening, 0-2% project definition) carries an expected accuracy range of -50% to +100%.
The DCMA 14-point schedule assessment sets a threshold of zero tolerance for negative float in a CPM schedule, since negative float signals a hard-constraint-driven delay to project or milestone completion.
Under AACE RP 18R-97, approximately 80% of projects are expected to fall within their stated estimate-class accuracy range when contingency has been addressed appropriately (an 80% confidence interval convention).
The DCMA 14-point schedule assessment sets a threshold that no more than 5% of a CPM schedule's total incomplete task duration should carry total float exceeding 44 working days (the 'high float' check).
The DCMA 14-point schedule assessment sets a threshold of 0% tolerance for negative lag (leads) in a CPM schedule, since leads distort the network and make forward/backward-pass float calculations unreliable.
The DCMA 14-point schedule assessment requires that no more than 5% of schedule activities have missing predecessor or successor logic ties (excluding the project start and finish milestones).
The DCMA 14-point schedule assessment requires that at least 90% of all activity relationships in a CPM schedule be Finish-to-Start (FS) logic ties for the schedule to pass this quality check.
