Our Approach

From Discovery to Live

We follow the agile phases used across UK government, so every step has a clear purpose, a clear output and a decision point before the next.

Phase 1Typically 4–8 weeks

Discovery

Understand the problem, the users and the data before committing to a solution.

  • User and stakeholder research
  • Current-state and data assessment
  • Go / no-go recommendation
Phase 2Typically 6–12 weeks

Alpha

Test the riskiest ideas cheaply with prototypes and proofs of concept.

  • Prototypes tested with users
  • Target architecture and data model
  • Plan and costs for Beta
Phase 3Iterative releases

Beta

Build the real service and data products, releasing in increments.

  • Working software and dashboards
  • Security and accessibility built in
  • Performance measures in place
Phase 4Ongoing

Live

Run, measure and improve, and hand over skills so your team owns it.

  • Service and KPI monitoring
  • Continuous improvement
  • Knowledge transfer and training

Not a government project? The same steps work for any organisation. We scale them to the size of the change.
