MACH was designed to remove delivery bottlenecks. When it became the target architecture, it inherited all the problems it was built to solve, and the measurement system changed from constraint elimination to architecture completion.
Programmes scoped to bottlenecks ship in weeks; those scoped as migrations ship diagrams
- Gartner's 2024 composable architecture research: 58% of enterprises pursuing composable delivery models report scope expansion as the primary cause of schedule overrun. Architecture as destination creates exactly this dynamic — each component demands full redesign, scope compounds, and the programme competes with the business value that justified the investment.
- MACH Alliance's 2023 member research: programmes that scoped MACH components against active delivery bottlenecks (integration latency, release cycle duration, channel duplication cost) cut feature-release cycles from quarters to weeks. Programmes scoped as platform migrations delivered architecture but rarely delivered velocity.
Scope MACH as acceleration sprints against named constraints, not as a standalone programme
Audit your current MACH posture against your active delivery constraints. Identify two or three specific bottlenecks and scope MACH components as acceleration sprints inside your existing platform architecture — not as separate initiatives with their own programme governance. Then ask the harder question: does your MACH programme have acceleration metrics, or only architecture diagrams? D6 treats MACH as a component-level accelerant mapped to specific delivery constraints, not as a destination. That distinction determines whether it shows up on your portfolio as a velocity multiplier or as a long-running programme with growing governance overhead.
