Two process projects can use the same notation and end up in completely different places. What separates them is where the work starts, who owns the process once the consultants leave, and whether anything is still being measured a year later.
A typical process-management project
The Dreher approach
Starting point
A modelling tool and a notation decision
The handovers where work actually stalls
Scope
Every process mapped, to the same depth
The processes that carry cost, risk or customer impact
Ownership
A methods team in a staff function
Named process owners in the line, with decision rights
Notation
Chosen first, then justified
Chosen after the process is understood — EPC, BPMN or UML as fits
Measurement
Process maps delivered
Cycle time, error rate and handover count, before and after
Durability
Gains fade after the project ends
Governance and KPIs, so the improvement holds
Alignment of interests
Tool vendor or implementation partner
Independent since 1992, no licence revenue
