RELY CASE STUDY SERIES · NO. 20
Tripling sales meant losing your best assemblers to subassembly, not production.
Every subassembly built offline was an experienced assembler pulled off your main line, at the exact moment demand was accelerating.
RELY takes full ownership of subassembly production and component procurement (turnkey builds, inventory visibility, and brand-level quality) so your line keeps its people and its space.

- 2,400+Subassemblies produced per month
- 2,000Sq ft production space freed
- LowerCost than internal build
- 700Assembly hours saved in 3 months
Subassembly was quietly becoming a second production line.
A fast-growing water heater manufacturer was tripling sales without the facility space or internal bandwidth to scale, and subassembly work was consuming both.
THE CONSTRAINT
- 01
SALES TRIPLED
Growth accelerated faster than facility space or internal bandwidth could follow.
- 02
ASSEMBLERS GOT PULLED
Subassembly builds repeatedly pulled the most experienced people off the main line.
- 03
STORAGE DISAPPEARED
Subassembly workstations and staging crowded out higher-value production space.
- 04
SOURCING STALLED
The sourcing team spent unsustainable time procuring and expediting components instead of new business.
