The Cost of Sequential Development
Finalizing industrial design before engineering review often produces a shell that engineering can’t build to spec (insufficient wall thickness for the PCB, no room for antenna placement) — forcing a design revision late in the process.
What Parallel Development Looks Like
Reviewing rough industrial design concepts against known engineering constraints (component sizes, antenna keep-out zones, thermal considerations) before either is finalized catches these conflicts early, when they’re cheap to fix.
