What is a Program Definition Phase (Formulation & Planning)?
Program definition is the first life-cycle phase, in two movements: formulation — shape the business case, secure the sponsor, size funding, and win chartering; then planning/preparation — build the roadmap, benefits management plan, governance structure, and initial component lineup. It ends when governance approves the program to start delivering.
The exam leans on sequence: vision and business case come before the roadmap; the roadmap before component charters. Answers that start delivery work during formulation are the trap.
Worked example
A bank's payments-modernization program spends eight months in definition: three in formulation (business case, €90M envelope, board charter) and five in preparation (roadmap with three tranches, benefits register with named owners, governance board seated, first two component charters drafted). Colleagues grumble that "nothing's being built." Then delivery runs four years without a single structural surprise — the eight months were the build.
