ANONYMISED CASE STUDY — DEFENCE

Preparing the retirement of a legacy ERP without losing the enterprise’s memory.

An international SAP transformation in which archiving, data governance and adoption had to progress together.

01 — SITUATION

Securing the transition to S/4HANA

A European defence group was preparing to retire SAP ECC6 across five countries, with more than 2,000 users and a significant volume of historical data to preserve.

02 — INTERVENTION

Connect data, governance and use

Structuring the JiVS archiving framework, clarifying accountabilities, coordinating internationally and integrating access to historical data into the S/4HANA roadmap.

03 — OUTCOMES

A scalable capability

Seamless access to historical data, controlled replication, an authorised reference source and observed time savings of 20–50% depending on use. The pilot prepared the way for group-wide rollout.

EATO PERSPECTIVE

Historical data is not an isolated technical issue.

It affects compliance, accountabilities, decision quality and user confidence. Architecture becomes valuable when it simultaneously secures the target state, governance and adoption.
