How we work
What goes into the work.
See the decisions behind delivery. Follow the work to handover.
Context · Delivery · Evidence
01 · Understand the requirements and constraints
Read each project in terms of the users, systems, records, and service risks that shaped it. The starting point is the requirement to meet and the constraints the team had to work within.
02 · Plan the solution and delivery
Look at how technical choices connect to scope, dependencies, and delivery responsibilities. Architecture, vendor decisions, and change planning help explain how the work was organized.
03 · Verify readiness through the change
Consider the checks relevant to each change: workflow testing, control review, migration readiness, or recovery. Look for the evidence behind a readiness decision and the issues that still needed attention.
04 · Prepare for support and handover
Look beyond implementation to the documentation, monitoring, escalation paths, and operating owners described in the work. Support evidence and handover responsibilities help explain how a delivered system is meant to be maintained.

Read case study →How to evaluate the work
Look at the decisions behind the technology.
Each project has a different starting point. The useful questions are what needed to change, how the work was planned, and how the result would be supported.
Constraint
What records, users, integrations, deadlines, service risks, or regulatory concerns shaped the work?
Key decisions
How were scope, architecture, controls, vendors, change windows, and accountable owners decided?
Verification
What evidence showed that the workflow, migration, control, recovery, or support path was ready?
Handover
Who owned the system after delivery, and what documentation, escalation, support, and improvement path remained?
