LeanIX and Citadel have worked with one another to gain access to many markets. Citadel can leverage the Saas-based solution across vast geographical regions, and thanks to LeanIX's consistent output of new functionality, the exchange of ideas and services between the two partners is a force multiplier when it comes to supporting client organizations.

Fundamentals of the partnership

As the major LeanIX partner in the Asia Pacific region, Citadel is able to provide incredibly localized support. Its competency in securely managing sensitive information is evidenced by both the handling of their own applications and its own security credentials (e.g., IRAP assessments,ISO27001, etc.), and thanks to its broad reach across the Australian landscape,Citadel can draw upon the joint expertise of its own workforce and network of associates when advising clients on how to best maintain architectural landscapes.

“Our Department selected LeanIX to support our Enterprise Architecture portfolio and increase EA adoption across our organisation. The Citadel Group delivered the jumpstart-onboarding project which was conducted over 4-weeks and involved consolidating our key Enterprise Architecture data sources that enabled us to produce reports such as Applications Heat Maps, Matrix, Metrics and Roadmaps. This project enabled us to rapidly establish the foundation for our current EA use cases and plan for future EA use cases.”
