What Is Changing
Programs can turn a composable architecture approach into a standalone migration. Scope expands, governance grows, and the business value that justified the change waits.
Why It Matters
Architecture should enable delivery, not compete with it. When the portfolio measures components migrated rather than constraints removed, velocity becomes invisible.
The 6xD Reading
Through D6, MACH is an accelerator applied to a bottleneck. Through D3, it should strengthen a coherent platform architecture rather than create a parallel destination.
Leadership Takeaway
Identify two delivery bottlenecks and scope MACH components as short acceleration sprints with an explicit cycle-time or reuse measure.
