Application rationalization is a journey

Take inventory

You can’t effectively manage what you don’t see. The first step in your application rationalization journey is to inventory all your applications, wherever they live. With this complete picture, you can see everything in one place and prepare for next steps of assessing and managing.

Assess value

Carefully analyze each application and understand its business impact. This is the time to understand what value each application brings, identify duplicates, and prepare for the appropriate action to streamline your business.

Plan and manage

Using the 5 R’s methodology, plan what to do with each application. You’ll keep some as-is, others you’ll retire, and others you’ll invest in more to maximize your value.

The 5 R’s of application rationalization:

  • Retain: Keep the application as is
  • Retire: Remove from service
  • Rehost: Lift and shift (migrate elsewhere)
  • Replatform: Upgrade the application and re-install on new platform
  • Refactor/Reimagine: Re-architect and rewrite the application to move towards modern architectures like cloud native, serverless, microservices, etc.
