For the majority of organisations the majority of their processes are fairly standard and can be bundled into a "one size fits all" approach that the purveyors of forced obsolence and subscriptions for this like.
Unfortunately, the majority of organisations have the odd existing, and often critical, business process that is non-standard, or at best are industry specific. These are the sticking points for the blinkered "push it to the cloud and hope it works" approaches. The old 90/10 rule.
