Story splitting FAQ
How do I know a story is too large?
Three signals: the team can't agree on points (every estimate is wildly different), the story has more than ~5 acceptance criteria, or the team feels like splitting would help but isn't sure how. If any two are true, split. More in what makes a good user story (INVEST applied).
What if no pattern fits cleanly?
Most stories fit at least one of the eight patterns. If none fit, the story might be a chore, a research task, or a bundle of unrelated work; name it accordingly rather than forcing a split.
Should every split story deliver user value?
Yes. The point of splitting is to ship working increments, not to break work into smaller technical tasks. If a split story can't be demoed, you've split horizontally (frontend/backend): split vertically instead.
How small is too small?
If the story is under 1 point and ships in less than half a day, it's probably overhead-heavy. Bundle it with related small stories. The 1-3 point sweet spot tends to optimise for both forecastability and shipping cadence.
What about the spike+build pattern; isn't it a cop-out?
It's only a cop-out if the spike never produces a decision. Timebox the spike (1-3 days), require a written output, and force a split decision at the end. If teams default to "spike everything", that's a refinement problem.
Why is workflow-steps the most common pattern?
Most user-facing stories are sequences. The first step is almost always shippable on its own (even if behind a flag), and each step proves part of the path. Workflow-steps is the default; try the others when it doesn't fit.
