A specification with aqua margin flags turning, frame by frame, into a finished software interface

Software starts with the spec.

Senior analysts write the requirement that your team, or our AI, builds from.

Ask before you build.

Try it: pick a requirement and open the questions a senior analyst asks first.

The requirement

A customer can send money to a saved payee.

  • What if the payee was deleted on another device?

    Acceptance criterion: The transfer is rejected with “This payee no longer exists”, and nothing is debited.

  • What if the bank's API times out?

    Acceptance criterion: After 10 seconds the transfer shows as pending. It is never sent twice, and the customer is told when it settles.

  • What if the amount is zero or negative?

    Acceptance criterion: The form will not submit, and says why next to the amount.

Most late releases trace back to one sentence two people read differently. A senior analyst finds it before anyone writes code.

What if the payee was deleted? What if the bank's API times out? What if the amount comes back negative? Each answer goes into the spec as an acceptance criterion an engineer can build from and a tester can run.

That document is what we sell. Your engineers build from it, or Etheria does, or we teach your analysts to write it.
