Its kinda technical mumbo jumbo for processes?

Appearantly its pretty much worth because they been bought up by sap.

Sorry if it does not belong here. But i really dont understand these management process optimization tools and why they should be so important? We do our stuff with confluence and jira and thats it. But we are also a software conpany nothing todo with hardware...
