When to Pick an Integrated Motion Assembly

Integration cost is usually hidden in coordination

A loose stack seems flexible until the project starts paying for bracket rework, harness changes, and duplicated validation notes. That cost should be made explicit early.

Integrated motion is strongest when ownership, interfaces, and FAT scope are all easier with one release package than with several vendors.

• Count coordination loops, not only material cost.
• Look at FAT scope and field support before deciding the stack.
• Use integrated assemblies when wiring and mounting assumptions move together.

Quick scoring model

const chooseIntegrated = coordinationLoops > 3 || harnessRisk === 'high' || fatScope === 'shared';
