What you will learn Not a chapter to read but one to do. Take one work item you have in flight, split it down to atomic units, and see for yourself whether those units stand in a single queue because of their dependencies.
"Not a finished one" is the part that matters. Finished work splits cleanly because you already know how it turned out. Only live work shows you the real dependencies.
No suitable item? Use this one — "Improve account deletion: capture a reason, mask personal data, and show deletion statistics to admins."
Write the item as a sentence, not a title.
If either is true it is already more than one item. That is the raw material for step 2.
Split at the conjunctions and make a list. You should end up with four or more lines.
| # | Atomic unit | Fits in one sentence? |
|---|---|---|
| 1 | ||
| 2 | ||
| 3 | ||
| 4 | ||
| 5 |
Most teams get this far easily. The next step is where it bites.
This is the point of the exercise. Between the lines, draw an arrow wherever "this has to finish before that can start".
| What you drew | What it means |
|---|---|
| No arrows at all | already independent. Rare |
| One continuous chain | splitting bought you nothing. Go to step 4 |
| One or two clusters | normal. Take just those to step 4 |
The middle row is the normal outcome. This is where most teams see that "we thought we had split it, but it was one queue all along" — the claim that splitting alone is not enough, verified on paper.
Take whatever the arrows tied together and cut it again by feature, not by layer.
An arrow still remains between A and B. When that happens, fix the contract first.
Fix the shape first and the rest becomes parallel. Those five minutes buy you days.
The final gate. Ask each piece one question.
| Answer | Verdict |
|---|---|
| Yes | ✓ it is atomic |
| "Something else has to ship first" | still tied. Back to step 4 |
| "It ships, but the screen is half-finished" | put it behind a switch and ship it off |
The third row is the trick. The constraint "you cannot ship something unfinished" creates half of all dependencies. If you can ship it switched off, that half disappears.
If the third is unchecked, go back to step 4. If you could not remove a single arrow, either the work is genuinely sequential or you are still cutting by layer.
1. What does it mean if step 3 produces one continuous chain?
That splitting bought you nothing. Five pieces in a queue still have to be worked through in order, so no parallelism appears. The point of a micro-sprint is independence, not size.
2. Explain "cut vertically" using this exercise.
Storage → screen → statistics is a cut by layer, and each waits on the last. Cutting by feature — "capture the reason" running from storage through to the screen on its own — means it waits for nothing.
3. Why does "it ships, but the screen is half-finished" count as independent?
Because you can ship it behind a switch, turned off. The constraint that unfinished work cannot ship creates a large share of all dependencies, and shipping it switched off removes that constraint.
