Build & Delivery

Put the agreed solution into operation and help people use it.

For clients ready to implement a defined solution. Barrington owns the client-facing delivery and coordinates the engineering team, bringing in specialist AI, data, integration and software engineering as required.

Book an advisory session

A dedicated hour with an experienced advisor. It commits you to nothing further.

When it fits
  • You have an approved need, a sufficiently defined solution and funding to deliver it.
  • You have existing discovery or a specification and need a partner to take it into operation.
  • You need one accountable lead across business priorities and engineering decisions.
What the client gains

A tested solution released into operation, with a supported handover and clear ownership.

What we do

What is included

  1. Mobilise a named engagement lead and the required engineering capability; confirm the delivery baseline, responsibilities and decision cadence.
  2. Build and integrate in increments, with regular demonstrations and controlled decisions about scope.
  3. Test functionality, access, data handling and operational behaviour. For AI features, evaluate performance on representative tasks and design appropriate human oversight.
  4. Complete user acceptance, prepare the release and train the people who will use and own the solution.
  5. Deploy, stabilise and hand over documentation, monitoring, support responsibilities and the route for future changes.

What you receive

  • The agreed working solution and its integrations
  • Relevant test and acceptance evidence
  • Release and rollback arrangements
  • User guidance and operational documentation
  • A handover to your team or an agreed ongoing service, with a defined stabilisation period

Scope and boundaries

  • Where you bring existing discovery, we review it and resolve gaps before committing to the build scope.
  • We commit to fixed pricing only after sufficient discovery. Where uncertainty remains, the work is phased or capped with review points.
  • The proposal states which data migration, integrations, environments, licences, training and support are included.
  • Business benefits are measured after release against the agreed baseline; technical release alone does not establish them.
How it starts

Three steps to a decision

  1. Step 01

    Agreement on the solution, its owner and what needs to improve for the investment to be worthwhile.

  2. Step 02

    A review of existing discovery, design and acceptance criteria, closing any gaps.

  3. Step 03

    A delivery proposal with milestones, assumptions and change control.
