ARUKUS / APPLICATION MODERNISATION
Keep the business knowledge. Improve the application.
Understand the legacy workflow, technical constraints and migration responsibilities before choosing the rebuild scope.
A long-running application often contains valuable process knowledge alongside outdated dependencies and difficult user journeys. Modernisation starts by identifying what must remain reliable and what is preventing the team from moving forward.
Review the current application
Map users, integrations, data, scheduled work and operational dependencies. Identify unsupported components, difficult releases and repeated work in the user journey. Review source and environment access before proposing a technical route.
Choose a practical scope
Compare targeted upgrades, phased replacement and a broader rebuild. A phased approach needs clear boundaries between retained and new components. A rebuild needs a migration and acceptance plan that preserves the business meaning of the records.
Prove continuity through testing
Use representative data and complete tasks, including reports, permissions and failed interfaces. Plan reconciliation, cutover and recovery before replacing a business-critical workflow. The choice of framework follows maintainability, operating requirements and delivery scope.
Planning the engagement
What should we bring to the first discussion?
Bring a process example, current system information and the people who own the work. A returned record or failed handover helps establish the difficult cases.
How is the scope agreed?
The proposal identifies deliverables, assumptions, acceptance criteria and the responsibilities of each team. New requirements are assessed through an agreed change process.
What happens after release?
Handover, stabilisation and continuing support are specified in the engagement. Coverage and service targets are agreed rather than assumed.
