What duration compression technique typically adds risk when it's used during a program?

Lead time generation is not a recognized standard duration compression technique in the PMBOK Guide or the Standard for Program Management.

Fast tracking adds risk because it forces activities to overlap before preceding work is complete; if the outputs of an earlier activity change, the work done in parallel may need to be redone, creating rework risk and potential for increased defects that would not occur in a sequential schedule.

Resource leveling heuristics adjust resource assignments to resolve overallocation and smooth usage; they typically extend the schedule rather than compress it and do not inherently add execution risk.

Crashing compresses the schedule by adding resources to critical path activities, which increases cost but does not typically add the technical execution risk introduced by fast tracking's parallel work approach.
