SOFTWARE DELIVERY FRAMEWORK

PRISM OS: software delivery you can see and sign

PRISM OS is our software delivery framework. It starts with a signed Problem Brief and closes every phase with a document you approve, because most builds fail before the first line of code.

Problem Brief

The problem, users and success measures, written down and signed before any build.

Signed before the next gate opens

THE PROBLEM

Where most AI-assisted builds actually fail

  • The problem was never written down, so everyone built a different one.
  • AI writes code fast, which means unchecked assumptions ship fast too.
  • Nobody measured quality until users found the defects.
  • The handover was a repo link, not a system the client could run.

What that costs you later

Rework, a second vendor, and a product nobody trusts. PRISM moves those costs to the start, where they're cheap to fix.

THE FIVE GATES

Five phases. Five signatures.

Each phase closes with a document you approve. The next phase cannot start without it.

P

Plan

We define the business problem, users and success measures.

You sign: Problem Brief
R

Research

We validate journeys, data and technical risk.

You sign: Validated journeys and frozen PRD-Lite
I

Implement

Working software on your data in short build loops.

You sign: Working prototype and architecture/eval report
S

Stabilise

Production hardening, security and UAT.

You sign: 3-click UAT sign-off
M

Maintain

Hosting, monitoring and improvements after launch.

You sign: IP handover and warranty

START HERE

Start with a Discovery Sprint

Gates P and R in 2–3 weeks, at a fixed price. You leave with a signed Problem Brief, validated journeys and a costed build plan, and you keep all of it whether or not you build with us.

For founders, this is where our MVP development services begin.

Startups

For AI products, the sprint includes eval design, the first step of our AI development services.

AI Engineering

AFTER LAUNCH

After launch: PRISM OPS

Host

Cloud hosting, uptime monitoring and cost reporting.

Shield

24/7 security monitoring, patching and backups.

Evolve

A monthly improvement budget, prioritised with you.

PRISM OPS is part of our managed IT services

FAQ

Questions before you book

Not covered here? Ask on the call.

Is PRISM a replacement for Agile?

No. Agile runs the sprints inside each phase. PRISM decides when a phase is finished, with a document you sign. Teams that already work in Scrum keep their ceremonies and add five clear decision points.

Can PRISM work with our existing dev team?

Yes. Your engineers can build inside the gates while we run the briefs, evals and evidence reviews. Many clients start this way and bring more of the build in-house after the first product ships.

What does the warranty cover?

Defects against the signed acceptance criteria, for 60 days after go-live. New features and changes in scope are planned separately through the Evolve budget, so the warranty stays clear and enforceable.
