D.E.C.O.D.E.
The six-stage sequence that governs Executive Architecture practice, from diagnosis through intervention.
Definition
D.E.C.O.D.E. is the methodological sequence that governs Executive Architecture practice, beginning with the diagnostic work of the Executive Architecture Review and continuing through architectural intervention: Discover, Examine, Compare, Observe, Design, Enable.
The six stages
| Stage | Function | Phase |
|---|---|---|
| Discover | Establish what architecture exists | Diagnostic (E.A.R.) |
| Examine | Understand how it evolved | Diagnostic (E.A.R.) |
| Compare | Compare the intended architecture with the lived one | Diagnostic (E.A.R.) |
| Observe | Locate architectural breaks | Diagnostic (E.A.R.) |
| Design | Define the future-state architecture | Intervention |
| Enable | Determine how the architecture is supported | Intervention |
How the stages fit together
The first four stages are the diagnostic method of the Executive Architecture Review. The last two are the intervention method, and they follow only after the gaps have been validated and prioritized.
D.E.C.O.D.E. is how Executive Architecture is practiced, from diagnosis through intervention. S.P.E.C.T.R.A. is what intelligence movement is examined along the way.
