Solo builders move fast until one thing breaks momentum: context fragmentation.
When concept notes, CAD changes, firmware assumptions, and decisions live in separate places, iteration slows down fast.
This guide shows how to run a solo workflow that preserves context across the full build cycle.
Start here: Set up your workflow in Haitch
You are probably losing context if:
Maintain one short brief containing:
Do not spread this across multiple docs.
For every major output (concept variant, CAD revision, firmware update), attach one sentence:
This changed because...
That sentence prevents 80% of future confusion.
Do not bounce randomly between tools.
Use a 48-hour intent window:
Switch only when the current workspace no longer reduces uncertainty.
Tasks tell you what to do.
Assumptions tell you what can break.
Keep a short list of active assumptions with status:
After every revision cycle, log:
Without this, rework compounds.
Once a week, ask:
1. Can I explain current product state in 3 minutes?
2. Do CAD and behavior assumptions still match?
3. Are unresolved risks explicit?
If not, pause new feature work and repair the narrative.
At the end of each work session, leave one clear instruction for future you:
Next: validate enclosure tolerance after board placement update.
This is the cheapest productivity lever in solo hardware work.
Use this 30-minute closeout checklist:
1. Update current decision statement.
2. Log one revision note.
3. Confirm next workspace and next action.
4. Mark one assumption as valid or uncertain.
Do this daily and you will protect velocity.
1. Too many disconnected tools too early
Use fewer tools until complexity requires more.
2. No explicit handoff to yourself
Leave one next-step note before stopping.
3. CAD and firmware drift
Run weekly cross-check between geometry and behavior assumptions.
4. Decision amnesia
Always attach reason to changes.
Because one person is switching roles constantly: founder, designer, engineer, and operator.
Keep tool-specific details where needed, but maintain one shared decision narrative.
Daily closeout note + weekly context integrity review.
Yes, but the discipline overhead is higher because context does not carry automatically.
Solo velocity depends less on raw speed and more on narrative continuity.
If your decisions, artifacts, and assumptions stay connected, you will iterate faster with less rework.
