Application Portfolio Management
Rationalise your application portfolio — identify redundancies, end-of-life systems, and consolidation opportunities to reduce total cost of ownership.
Understanding This Service
What It Is
A structured assessment of your enterprise application portfolio using the TIME model — Tolerate, Invest, Migrate, Eliminate — to identify redundancies, end-of-life systems, and consolidation opportunities that reduce total cost of ownership.
Who It's For
CIOs, enterprise architects, and IT finance leaders in large organisations carrying a complex, historically grown application landscape with unclear ownership, duplicate functionality, and rising maintenance cost.
When It's Needed
During enterprise architecture reviews, ahead of major ERP or platform migrations, post-merger IT consolidation, or when application maintenance costs are growing without corresponding business value.
