Phasing

Generally, a CD would not be split and CD-2 is never split. For some projects, it may be appropriate to phase the work (into smaller, related, complete and useable projects) and split or phase the CD. In those instances, it may be appropriate to garner CD-0 and CD-1 approvals for all the smaller projects collectively and simultaneously. Each project must have its own distinct performance baseline (CD-2) with clearly defined and documented technical scope, cost, schedule and funding profile including consideration for all applicable contingencies.

A CD-3A phase may be needed for long-lead item procurement. If CD-3A is anticipated, the need for this decision and the process should be documented in the PEP or Tailoring Strategy.
