Application Rationalization Framework

Most organizations know their application portfolio has grown beyond what the business actually needs. Few do anything systematic about it.

According to a LeanIX survey, 85% of companies have not optimised their application portfolio, and 50% run no regular rationalization initiative.

The result: budget tied up in applications that underdeliver, IT teams managing complexity they cannot fully map, and every transformation programme starting from a position of accumulated debt.

An application rationalization framework gives you a repeatable way to assess what you have, decide what to keep, and act with confidence.

What's in this framework?

This one-pager walks through the four core steps of a structured application rationalization initiative:

1. Inventory your applications
   Group your applications into manageable sets — by business domain, lifecycle stage, or organisational unit. A scoped inventory is the foundation everything else depends on.

2. Define your assessment scope
   Not every application needs the same level of scrutiny. Identify which subset has the most cost, risk, or strategic relevance, and focus your assessment there first.

3. Apply the Gartner TIME model
   Classify each application in scope as Tolerate, Invest, Migrate, or Eliminate — based on its technical fit and functional fit. TIME gives you a defensible, structured basis for portfolio decisions.

4. Build a review cycle
   Application portfolios change. A one-off assessment decays quickly. The framework includes guidance on how to keep your rationalization practice current as your portfolio and business priorities evolve.

SAP LeanIX customers who run structured rationalization programmes have achieved $50M in savings, avoided 30% of unnecessary support costs, and removed over 1 million redundant applications within six months.

The framework shows you where to start, what to measure, and how to build stakeholder support for the decisions you need to make.
