The Decision Spine Framework

Most organizations have an architecture repository, not a decision system. When an urgent strategic question arrives — can we introduce this AI assistant, should we retire this platform, which initiative gets funded — they cannot assemble a timely, defensible answer. The decision spine fixes that: nine connected facts, traced end to end, plus the six decision products that replace the diagram graveyard.

Pair this with Enterprise Architecture as a Living Decision System for the fuller argument on why repository-first EA fails at the moment it matters most.

What’s inside

• The nine-point spine: strategic outcomes through measures & evidence, connected so any team can trace change from purpose to result
• The six core decision products: capability map, value-stream map, dependency graph, executable guardrails, decision log, and technical debt portfolio — the six things a leader will actually use instead of hundreds of unused diagrams
