Drivers to Application Performance Monitoring

When I talk with customers, I like to find out what is driving them to implement an Application Performance Monitoring (APM) strategy. The most common reasons I hear are:
  • A business critical application failed and the business demands change.
  • There is chronic, unresolved pain with one or more applications that lead people to conclude that the current processes are unsustainable. Either the business or IT demands a change.
  • A double mission critical (an actual term I heard a customer use!) application is rolling out, and the business is not willing to take any chances on the failure.
  • A new IT executive wants to provide better alignment/visibility to business-relevant factors rather than relying on just technical data.
What other reasons do you see for implementing an APM strategy?
