What you will learn How far down to split work, why independence matters more than size, and what "breaking dependencies" actually means.
Split work down to units that cannot be split further.
Each is one sprint. It can finish in minutes.
Confusion arises here. "So we just cut the backlog finer?"
Splitting alone is not enough. If the pieces depend on each other, you still process them in order and get no parallelism.

S1 -.->|"Split independently"| S2The left has three pieces but they stand in a line. 2 cannot start until 1 finishes. Splitting achieved nothing.
The right does not wait on itself. They run simultaneously.
| Property | Result |
|---|---|
| Parallel execution | nothing waits, so ten at once |
| Small blast radius | one wrong means only that one redone |
| Zero wait time | no reason for everyone to gather at a sprint boundary |
| Clean context | each keeps only its own context |
The last matters a lot in practice. Hand over one large job whole and the context fills and consistency breaks; split into atomic units and each starts clean.
So what about work that genuinely has an order, like "DB schema → API → screen"?
Three approaches.
When you divide by stages (research separately, writing separately, review separately), each person waits idle on the previous stage.
Instead, divide into units that finish end-to-end on their own. (Engineering historically calls this 'vertical slicing', but the essence is completing independently without waiting on others, not the spatial metaphor.)
Each piece goes all the way to completion on its own. Agents proceed concurrently without blocking on other teammates.

L3 -.->|"Switch to Independent Units"| F1 & F2 & F3If tasks truly must be separated, fix the boundary format before building.
With the format settled, neither has to wait for the other.
Do not force it. Some work — database migrations or mandatory legal sign-offs — is inherently sequential. Bundle that as one micro-sprint.
Do not try to make everything parallel. The goal is to parallelise what can be parallel, not to split things by force.
Put the work in front of you and ask:
The third (deployed or shared on its own for immediate use) is the strongest test. If it can be used separately it is definitely independent.
| If it | Verdict |
|---|---|
| Fits in one sentence | about right |
| Contains an "and" | still too big. Split it |
| Can be expressed in 2–3 tests | about right |
| Involves several teams | too big |
"And" is the signal. "Upload the photo and generate a thumbnail" is two things.
If people manage it, yes. Tracking ten sprints by hand is a job in itself. But automate the tracking and the count stops mattering. Atomic units become viable precisely because management cost fell.
The big picture lives in the intent. Micro-sprints are a unit of execution, not a unit of planning. The goal "improve member management" stays intact; only the execution is atomic.
1. Why is cutting the backlog finer not enough on its own?
Because if the pieces depend on each other you still process them in order. Three pieces standing in a line give no parallelism. Independence, not size, is the point.
2. What does "split into independent complete units (vertical slice)" mean?
Do not cut by phase or layer (research separately, design separately, development separately), which causes everyone to wait in line. Instead, cut into units that finish end-to-end on their own. When a deliverable or feature goes on its own from start to finish, multiple agents can build in parallel without blocking.
3. What is the strongest test of independence?
Whether it can be deployed on its own. If it can be completed, tested, and deployed separately, it is definitely independent.
