Build the software your team needs to do the job.
An internal tool, customer portal, or connection between systems, scoped around the people who use it and the person who will run it after launch.
Start where the current software falls short
Your team may be keeping a spreadsheet beside a system that cannot quite do the job. Customers may be emailing for information they should be able to see themselves. A vendor may have stopped work on a tool your staff still depends on.
Fifth Nine reviews what exists with the people using it. The first decision is whether to change the current system, buy a tool, or build something. An existing codebase is a place to investigate before committing to a rewrite.
Agree on what finished means
Name the person who will use the software, the job they need to finish, and the constraints the work has to meet. Put the access, integrations, testing, and release plan in the scope. Review working software with the people who will use it while changes are still manageable.
Plan ownership at the same time: where the code lives, who controls the accounts, how changes reach production, and who responds when something fails. Documentation and training are part of that handoff, with responsibilities agreed before development.
A build with a job to prove
For an AI workflow, the paid AI Audit establishes the baseline and a scope before the Build. Test the finished job against that baseline and train its owner. Ongoing review can continue through an operating-partner engagement.
For a product or integration outside that offer, agree on the engineering scope separately. The call is the place to explain what the software needs to do, what already exists, and where the work is stuck.
