Public and enterprise system integration (SI)

We connect separate work and data into one flow, and create public and enterprise information systems that you can still understand and manage after the build.

An integration structure linking different systems

What needs connecting is the business context, not just the systems.

We don’t stop at turning requirements into a feature list. We look at how staff actually work and at the limits of existing systems. By first defining the integration points and data standards you need, we design a structure you can understand and manage after the build.

Concept diagramIntegration flow linking separate systems through common standards
Concept diagram of the system integration flowIn the integration stage, existing business systems in each department or agency and external services such as payment, identity verification, and alerts are linked through common data standards. The connected data then feeds integrated work screens, where data is entered once and viewed together, and operating data such as settlements, status, and history. Integration errors go through a status check and reprocessing, then return to the integration stage.01AExisting systemsDepartment & agency data01BExternal servicesPayment · Identity · Alerts02IntegrationData standards · Auto-sync · Batch processing03AUnified screenEnter once · View together03BOperating dataSettlement · Status · HistoryIntegration errors are checked and reprocessedConcept diagram of the system integration flowIn the integration stage, existing business systems in each department or agency and external services such as payment, identity verification, and alerts are linked through common data standards.

Where systems are split, the same work gets done twice.

If this sounds familiar

  • Separate work and data

    Each department and organization uses its own system, so staff re-enter the same information or cross-check it by hand.

  • Limits of legacy systems

    New features and services have to be connected safely while existing assets stay in place.

  • A transition planned with operations in mind

    You need a realistic transition plan that covers not only the build schedule but also data migration, helping users adapt, and incident response.

From business analysis to transition, we cover the whole integration.

Business & requirements analysis

We lay out the current work, user roles, data flows, and external integration conditions in one structure.

System architecture design

We design the application, data, and interface structure with your existing environment and expansion plans in mind.

Integration implementation

We implement and verify connection points that fit your environment, such as automated integration between systems, batch processing, and data exchange methods.

Transition & stabilization support

We define the migration scope, verification criteria, and step-by-step transition procedures, and carry the work through to handover.

We transition systems in four steps, from assessment to stabilization.

  1. Current-state assessment

    We check in with business staff and review the current systems, then agree on the challenges to solve first.

  2. Integration design

    We bring work, data, screens, and integration structure together under one set of design standards.

  3. Implementation & verification

    We build feature by feature and verify each one against real business scenarios and integration conditions.

  4. Transition & stabilization

    We move data and the user environment over in stages and document what needs fixing during operations.

Project deliverables

  • Current-state business and requirements specification
  • Service and system architecture
  • Interface and data integration specification
  • Implementation and verification results by feature
  • Data migration and transition plan
  • Handover documents

The exact scope and deliverables are confirmed in early discussions.
