/ 01THE MANDATE · WHY THIS PRACTICE MATTERS NOW

Not a software installation — a transfer of business capability.

Capital-markets platform change is rarely a software installation. It is a controlled transfer of business capability across products, desks, workflows, data models, interfaces, controls, and people.

Programs that treat it as configuration inherit the estate's blind spots. Programs that treat it as capability transfer answer four questions before anything moves.

/ 03PROBLEM LANDSCAPE · THE APPLICATION TOPOLOGY

Where institutions lose control.

01
Scope Without Boundaries

Programs begin with a product name rather than an explicit capability, data, and operating-model scope.

02
Interface Blind Spots

Downstream dependencies emerge late because inventories and interface contracts are incomplete.

03
Weak Data Evidence

Converted records look plausible but lack lineage, reconciliation, exception ownership, and sign-off.

04
Testing Too Narrow

Happy-path functional tests overlook volumes, controls, timing, recovery, and operational exceptions.

05
Cutover by Calendar

A date drives the migration even when readiness criteria, support coverage, and rollback are immature.

06
Adoption Afterthought

New workflows are delivered without ownership, training, metrics, or retirement of old behavior.

We test whether the program can execute a safe transfer of capability — not merely whether the target platform can be configured.

MDMI PERSPECTIVE · 2026
Platform Implementation & Migration: The Enterprise Architecture, Operating Model and Transformation Imperative
PRACTICE 01OFFICIAL BRIEF

Not a technology initiative — an interconnected enterprise capability.

The practice-area brief argues that platform implementation and migration must be governed as one system — capability scope, interface contracts, data conversion evidence, testing depth, cutover command, and adoption — rather than a vendor configuration exercise. It sets out the operating model, the reconciliation standard, and the wave plan this page walks through.
