Key takeaway
Low quantity does not mean low complexity. A small build still needs sourcing, revision control, testing and handover discipline.
Low-volume work has different risks
A one-off product can be hard to repeat if the design files, sourcing notes and test method are not captured. The commercial quantity is small, but the consequence of failure can still be high.
Plan component availability early
Parts should be selected not only for function but for availability, lifecycle, substitutes and assembly practicality.
Document the build pack
A usable build pack includes schematic, PCB files, BOM, firmware, programming steps, mechanical notes, revision history and acceptance tests.
- BOM and substitutions
- Revision notes
- Programming files
- Test criteria
- Known limitations
Keep future support in mind
Even if only one unit is needed today, future support becomes easier when the knowledge is organised and readable.
