Get · Sort · Do · Prove · Improve
Every unit of work — a request, a deal, a deliverable, a decision — travels the same five stages. The point of the lifecycle is not to describe them, but to read across all five at once.
A status report tells you what moved. GSDPI tells you what converted.
Most reporting watches activity inside one function. Reading the model end to end changes what you can see — and where you look for the break.
Where the lifecycle exposes the break.
Read across all five stages and the pattern is rarely local. Three things surface almost every time.
Handoffs, not tasks
Work stalls between stages — in the intake-to-sort and do-to-prove seams — far more than inside any one of them.
One breaking stage
A single stage usually throttles the whole model. Fix elsewhere and throughput doesn't move; the constraint just re-asserts.
Prove is the weak link
Do and Prove carry the heaviest pain — work is executed, then can't be shown to have held. The result is reported, not proven.
GSDPI carries the principle — and has its own body of work.
The lifecycle operationalizes Zero-Based Transformation and is made actual and provable by the instruments. Its full discipline — stages, gates, and practice — is detailed here and across the ETEGY methodology.
