Core Systems

Core Banking System Implementation and Modernisation

Independent support for assessment, selection, implementation, integration, migration, testing, training, go-live, and stabilisation.

Requirements and Selection

Define institutional needs and evaluate solutions against transparent criteria.

Implementation Governance

Coordinate scope, workstreams, vendors, risks, decisions, assurance, and reporting.

Readiness and Stabilisation

Verify data, integrations, controls, users, support, cutover, and post-launch operation.

Overview

Control the Full Core System Change Lifecycle

A core system programme affects products, customers, finance, operations, reporting, controls, data, integrations, and staff. We provide structured guidance across the lifecycle so that decisions remain traceable, readiness is evidenced, and the institution—not only the technology vendor—owns the outcome.

What We Deliver

End-to-End Core System Support

Support can begin before procurement, during implementation, or when an existing programme needs independent assurance.

01

Current-State Assessment

Review business needs, system limitations, data, integrations, controls, support, and change drivers.

02

Requirements and Selection

Develop evaluation-ready requirements, scenarios, criteria, demonstrations, and due diligence.

03

Programme Governance

Define workstreams, milestones, responsibilities, decision rights, risk controls, and assurance.

04

Configuration and Integration

Maintain traceability from approved requirements through configuration and connected systems.

05

Testing and Migration

Coordinate functional, integration, security, performance, user, reconciliation, and migration assurance.

06

Cutover and Stabilisation

Prepare go-live criteria, support, rollback, issue management, handover, and post-launch monitoring.

Our Approach

A Stage-Governed Implementation Approach

Readiness evidence supports decisions at each major transition.

  1. 1

    Assess and Define

    Establish objectives, requirements, scope, baseline risks, and success criteria.

  2. 2

    Select and Mobilise

    Evaluate the solution and prepare governance, plans, teams, and delivery controls.

  3. 3

    Build and Prove

    Configure, integrate, migrate, test, train, reconcile, and demonstrate readiness.

  4. 4

    Launch and Stabilise

    Execute cutover, manage early-life support, resolve issues, and transfer ownership.

Common Questions

Frequently Asked Questions

How Does an Engagement Begin?+

We begin with a focused discovery conversation to understand your objectives, current environment, constraints, stakeholders, and required outcomes before recommending a scope.

Can the Work Be Delivered in Phases?+

Yes. Work can be organised into assessment, planning, implementation, assurance, and capability-transfer phases so that investment and delivery risk remain manageable.

How Do You Support Internal Teams?+

We work alongside business, technology, risk, compliance, and leadership teams with clear responsibilities, documentation, decision records, and practical knowledge transfer.

Can You Work With Our Existing Vendors?+

Yes. We can work with existing technology vendors, implementation partners, advisers, and internal teams while keeping responsibilities, decisions, dependencies, and assurance requirements clear.

What Information Is Needed to Define the Scope?+

Useful inputs include the intended outcome, current environment, affected stakeholders, known constraints, relevant obligations, expected timing, and any previous assessments or plans that can be shared appropriately.

How Is Confidential Information Handled?+

Information is limited to what is necessary for the engagement and handled through agreed access, confidentiality, security, retention, and communication arrangements. Sensitive information should not be sent before suitable safeguards are in place.
