Context
The client, a major European financial group,
was facing a progressive loss of control over its
application architecture.
Many applications were no longer referenced correctly,
some without identified owners and lacking security follow-up.
Internal repositories such as Magellan were incomplete and inconsistent
across entities, preventing any consolidated and reliable vision of the
application landscape.
Challenges
- • 470 applications across multiple entities and technical domains,
- • No identified owners for a significant part of the portfolio,
- • Highly heterogeneous local classification and evaluation practices,
- • Need for fast remediation without operational disruption.
AGCG Approach
- • 1. Diagnostic: review of the Magellan repository, duplicate identification, and definition of critical data to be restored.
- • 2. Classification: categorisation by nature, status, domain and criticality.
- • 3. Owner designation: collaborative workshops to assign IT and business owners and eliminate orphan applications.
- • 4. Consolidation: delivery of a consolidated map, repository updates, and executive reporting to the COMEX.
Results
- • 470 applications inventoried and documented,
- • 100% assigned to both an IT and business owner,
- • Magellan repository rebuilt and strengthened,
- • Consolidated map by domain and criticality,
- • Durable application governance established.
Why This Case Is Representative of Many Organizations
The situation encountered in this financial group is increasingly common, particularly
in large organizations with complex and historically layered information systems.
Application portfolios tend to grow organically, with successive additions that are
insufficiently governed, leaving behind:
- obsolete or unmanaged applications,
- inconsistent or incomplete repositories,
- undefined responsibilities,
- weak prioritization of risks and investments.

of their application landscape and secure it sustainably.
