What is the best way to manage application rationalization and organize the data in Apptio?

Hi Isabella

I would manage the Application Master Data to do this, but that is related to Cost Transparency 11.8. Here is it important to maintain the column "Application Retirement Date". By maintaining that are you lighting up the report:

IT Management -> Applications -> New & Retired

You can use that report to communicate how many applications has been retired since you started your initiative.
