It seems super strange to adopt the market leader’s processes. You’d think the spirit should be that you can outdo/outcompete then instead of adopting what they’re doing...
Even a bleeding-edge company will hit an obstacle they cannot improvise through (like in QA or Compliance). That's when enterprise software creeps into an otherwise lean operation.
Unless your company has thousands of employees and billions in revenue, Google/Microsoft/Apple processes are probably not for you.
Then you probably don't need and shouldn't buy SAP.
