Introduction
Mechanical design work generates complex, intertwined tasks: multiple part numbers in motion simultaneously, design changes arriving from different directions, meeting action items with different owners and deadlines. Keeping this in your head is not reliable — something will be dropped. A simple, daily-maintained TODO system prevents the drops.
Why Mechanical Design TODO Management Is Different
General task management advice does not fully apply to mechanical design because:
- Tasks are organized by part number, not by project alone. “Check drawing” means nothing; “Verify tolerance on XXX-001 after design change” is actionable
- Tasks frequently involve waiting for others. “Awaiting approval from colleague A” is a valid task state that standard apps do not handle well
- Interruptions are high-frequency. Your day’s plan can be completely reorganized by a single phone call
The Core System: Three-Element Daily Entry
Each task entry uses three elements: date, part number / project reference, and current status including next action owner.
u3010May 27 (Tue)】 ○ XXX-001 Hole pitch correction → Reviewed by A ✓ ● YYY-002 Wall thickness change → In progress (machining calc pending) □ ZZZ-003 Assembly interference chk → Not started (by May 30) □ TODAY Meeting prep material → Not started (due today)
Symbol key: ○ = complete, ● = in progress / waiting, □ = not started
The “status” field should answer: who holds the next action? If it is you, what specifically needs doing? If it is someone else, what are you waiting for and from whom?
Daily Rhythm
Morning (5 minutes): Write today’s tasks — carry over from yesterday, add anything new. Mark the 2–3 highest-priority items to do today. Having an ordered list before starting work eliminates the morning “what do I do first?” delay.
End of day (5–10 minutes): Update status of each item. Complete items get ○. Pending items get a brief status note. Items rolling to tomorrow get the reason and due date noted. This morning-evening cycle means you start every day knowing exactly where everything stands.
For Multiple Projects: Page Separation
When carrying three or more simultaneous projects, separate pages by project:
- Cover page: This week’s project list — project name and deadline only
- Project A page: Daily task detail for Project A
- Project B page: Daily task detail for Project B
- Interruption page: Miscellaneous urgent items that do not belong to a named project
Start each day at the cover page (overview), then open the relevant project page for the task you are working on.
The Long-Term Benefits of Consistent Logging
After several months of consistent use, the notebook reveals:
- Your actual work speed per task type (how long does drafting really take you?)
- Your personal bottleneck patterns (“I always wait too long on colleague B’s reviews”)
- Ready material for progress reports and project handovers
FAQ
Q. Should I use digital tools or a paper notebook?
A. For mechanical design work with frequent part number references and mid-meeting jotting, a paper notebook is consistently faster and more practical than switching between apps. Try the paper system first; adopt digital only if paper is genuinely inconvenient for your specific workflow.
Q. I have too many tasks to track. How do I start?
A. Write down every task you are aware of — no filtering, no prioritizing yet. Then pick the three that must happen today and mark them. Work only from those three until done or blocked. The full list is for reference; the today-list is for action.
Q. How do I handle tasks that are just “waiting for someone else”?
A. Keep them on the list with the ● (waiting) symbol and a note of who you are waiting for. Review them once a day. If an item has been waiting longer than expected, that review prompts a follow-up. Invisible waiting tasks are how important things fall through the cracks.
