Decisions to make before building

Building quickly helps when the product direction is clear enough. A few decisions should be made together before code is written.

The first user

Choose the group that needs the outcome most. An audience that is too broad makes interface language and flows harder to decide.

The primary task

Define the most important action a user must complete. This flow becomes the basis for pages, data, validation, and testing.

Data sources

Describe what users create, what arrives from other systems, and what must be protected. These choices shape the architecture from the beginning.

Operational boundaries

Decide who runs the product after launch. Products that need administration, moderation, or support need those flows in the first useful version.

A definition of done

Write conditions that can be checked. For example, a user can register, complete payment, and access what they purchased. Concrete definitions make testing honest.

These decisions do not prevent change. They make the next change easier to understand.
