Demonstrating Redundant Business Applications Using Enterprise Architecture

Tuesday

I have a customer who wants to understand how Enterprise Architecture (EA) can be used to identify redundant business applications and demonstrate cost optimization opportunities.

For example, both Jira and ServiceNow are being used for project management, and the customer wants to evaluate whether one of them can be retired to reduce costs. Similarly, there may be other overlapping business applications across the organization.

Challenges:

  • Application costs are not directly linked to business applications.

  • Costs are maintained in a Company/Vendor table, linked via contracts and vendor management.

Ask:

  • How to show this via EA:

    • Present a clear comparison (e.g., Jira vs ServiceNow) to support rationalization and cost-cutting decisions?

Any best practices, data models, or real-world examples would be greatly appreciated.

Hi @dd31 

APM used to be about four stages:

  1. Build an application inventory
  2. Conduct basic rationalisation (i.e. - score the apps)
  3. Conduct advanced rationalisation (i.e. use TPM to look at technology risk)
  4. Make a decision (invest, sustain, migrate, retire)

 

Assuming you have your inventory, look at stage 2. I have written an article describing application scoring in depth here:

In terms of visualisation you can use the Bubble chart in EA Workspace to compare and contrast scored business apps.

 

I hope this helps!
