How long should a technical direction note actually be?
Short enough to read in two minutes. If it takes longer, it'll get skipped. Aim for one clear paragraph on the decision, a few bullet points on trade-offs, and a line or two on what's out of scope. You can always add more detail in comments as questions come up.
What if the direction changes after we've already shared the note?
Update it and say so. Add a short note at the top with the date and what changed. A direction note that's been honestly updated is far more useful than one that quietly goes stale. Your team will trust you more for being upfront about the shift.
Can Tindlo help keep these notes connected to the actual work?
Yes, in a practical way. You can create a work item for the direction note and attach files, links, and a brief directly to it. Because Tindlo shows work across time in shared Day and Week views, your team can see the note sitting alongside the tasks it shapes — not buried somewhere separate.
