06How we deliver

Working software,early and often.

Six stages, run in short iterations. Each one ends in something you can see and use, and the team that builds your system stays with it after launch.

  1. Stage 01

    Understand the challenge

    Workshops with the people who do the work. We map the current process, the data, the systems already in place and what success has to look like.

    OutputProblem statement, process map, success criteria

  2. Stage 02

    Define the solution

    We scope a first release that delivers value on its own: roles, permissions, integrations and the risks we need to retire early.

    OutputRelease scope, estimate, risk list

  3. Stage 03

    Design experience & architecture

    Interface design and technical architecture move together, so every screen has a data model behind it and every integration has a contract.

    OutputPrototype, architecture, API contracts

  4. Stage 04

    Engineer & integrate

    Short iterations with working software at the end of each one. You follow progress in a real environment, not in status reports.

    OutputIterative releases to staging

  5. Stage 05

    Test & launch

    Dedicated QA, acceptance testing with your team, data migration and a launch plan that includes a way back.

    OutputProduction release, onboarding, documentation

  6. Stage 06

    Maintain & evolve

    Monitoring, support and a living roadmap. The team that built the system keeps improving it.

    OutputSupport agreement, roadmap, regular releases

07The team

14 people.One engineering culture.
