Budget at completion (BAC) is the total authorized budget assigned to complete a defined scope of work. At the total project or contract level, BAC generally represents the Performance Measurement
How to Review an IMS Before Customer Delivery
An effective IMS schedule review confirms more than whether the file opens and passes a metric screen. Before customer delivery, the scheduler should verify contractual compliance, status integrity, network logic,
When Are Lags Appropriate in a Project Schedule?
Schedule lags are appropriate when a relationship requires a real, measurable passage of time and no work, resources, or meaningful progress occurs during that interval. A fixed curing, drying, cooling,
Hard Constraints vs Soft Constraints in Scheduling
The difference between hard vs soft constraints is how severely each one restricts a schedule’s response to network logic. In a forward-scheduled network, a soft constraint prevents an activity from
DCMA Lags Check Explained
The DCMA lags check measures how often positive lag appears in the logic relationships of an Integrated Master Schedule (IMS). The familiar screening target is approximately 5 percent or less.
DCMA Relationship Types and FS Logic
The DCMA relationship types metric measures the proportion of finish-to-start (FS), start-to-start (SS), finish-to-finish (FF) and start-to-finish (SF) relationships in a schedule. Under the commonly used 14-point assessment criteria, FS
DCMA Hard Constraints Check
The DCMA hard constraints check measures the percentage of incomplete activities restricted by Must Start On, Must Finish On, Start No Later Than, or Finish No Later Than dates. The
DCMA High Duration Activities
The DCMA high duration check identifies unfinished schedule activities with a baseline duration greater than 44 working days. Under the commonly used Defense Contract Management Agency (DCMA) 14-point schedule assessment,
DCMA Leads Check Explained
The DCMA leads check identifies predecessor relationships that contain negative lag. A lead allows a successor activity to start or finish before the relationship would otherwise permit. For example, an
Out-of-Sequence Progress Explained
Out of sequence progress occurs when an activity reports actual progress even though the predecessor condition defined in the schedule has not been satisfied. For example, a successor may start
