A story should be able to ship on its own

I've sat in planning meetings where time was short and the requirements were still fuzzy. We divided the work into chunks that looked sensible on a board: front page, search page, recipe page. Or database, backend, frontend, mobile.

The board looked organized. Delivery became tangled because each chunk needed most of the others before it could reach a user.

The recipe page that needs everything

Say you're building a recipe website and create a story called "Build the recipe page." It sounds contained until you unpack it. The page needs ingredients, cooking steps, nutritional information, images, and user comments. Those pieces need backend logic, database schemas, and API endpoints. The nutrition calculator depends on the ingredient structure. Search needs recipes to search.

Soon every task is waiting for another one. Stand-ups turn into debates about what "done" means, and the team can spend a sprint moving tickets without putting anything useful in front of a user.

This usually starts with good intentions. A user journey gives you pages, and a system diagram gives you technical layers, so either can feel like a natural way to organize the backlog. Under time pressure, those familiar boxes are especially tempting.

Cut a thin path through the system

For the recipe site, I would start with "display the recipe title and description." That slice includes the small amount of UI, logic, and data needed to work. It can ship. Then the team can add the ingredients list, followed by the cooking steps.

The schema and API work still exists. It happens inside each slice instead of becoming a separate story that produces nothing a user can see. After each slice, the team has working software, earlier feedback, and fewer dependencies to coordinate.

Watch for horizontal habits

A feature reaches through the stack. Calling it "frontend" or "backend" may make ownership look neat, but it also separates the work required to deliver something a user can touch.

I see a related choice in code structure: organize everything by technical layer, or group the code needed for a feature. Components bring markup and behavior together, and Tailwind CSS puts styling decisions alongside the markup. Those choices don't make a backlog shippable, but they reflect a similar preference for keeping related work together.

Even experienced teams drift back toward horizontal slices when they're rushed. I use one question to catch it: can this story ship on its own?

For the recipe site, that means the title and description can go live while the team is still working on ingredients. If the database schema is the only thing finished, we're still waiting.
