Most tasks work best at half a day to three days. That is small enough to estimate well, finish this week, and review in one sitting. Bigger than a week, split it. Smaller than an hour, it is probably a checklist item inside a bigger task.
Why size matters
Big tasks hide problems. A two-week task looks "in progress" for ten days. You find out it went the wrong way on day nine.
Big tasks are hard to review. A reviewer facing two weeks of work skims. Mistakes get through.
Big tasks are hard to estimate. Estimates for long, vague work are often wrong by half or more.
The sweet spot: half a day to three days
- You can picture the whole thing.
- It finishes before priorities change.
- One review covers it.
- If it goes wrong, you lose days, not weeks.
How to split big work
Split by deliverable. "Website" becomes homepage, pricing page, about page.
Split by stage. "Pricing page" becomes outline, draft, design, build.
Split by audience or case. "Help articles" becomes one per common question.
Split by risk. Do the uncertain part first, as its own task. "Test whether the import works with large files."
Example
Too big: "Launch the spring campaign" (3 weeks).
Split:
- Write the creative brief (0.5 day)
- Draft landing page copy (1 day)
- Design the landing page (2 days)
- Build and test the page (2 days)
- Write three emails (1.5 days)
- Make four social images (1 day)
- Set up tracking (0.5 day)
Each one can be reviewed against a clear brief.
When a task is too small
"Send the file to Sam" is a step, not a task. Group tiny steps into a checklist inside a bigger task. Otherwise your list fills with noise.
Each piece needs a done check
A small task without a done check is still vague. Add one line: "Done when the page works on Chrome, Safari and iPhone."
Estimate the pieces
The PERT calculator adds up best, likely and worst cases for each piece into an honest range.
Small tasks, quick reviews
In M-Tracker, each piece is a task with its own brief and done checks, under a project. Each one gets a first review when it is finished, so problems show up on day two, not week three. No screenshots and no activity tracking.

What about research that cannot be split?
Timebox it: "Two days to find three options." The output is the three options.

Yes. Stories that fit in a few days flow better through a sprint.
Work you can trust, without redoing it.
Your team gets feedback before work reaches you, or your client.
