My answer to What are the disadvantages of the business process reengineering methodology?
Answer by Ken Larson:
ISO 9000, TQM and many other buzz words have come along in recent years, all connected with business process re-engineering and related quality factors or achieving greater efficiency via “Lean” something or other.
In my experience these programs are not without merit if carefully managed and kept at an effective level of detail so they do not assume a life of their own and disrupt the organization in a costly fashion.
Functional interface points are the most sensitive. These are the critical areas where one functional organization meets another in the company.
Engineering Design meets Manufacturing
Finance meets Estimating
Marketing meets Project Management
Accounting meets Cost Control
Human Resources meets the Hiring Manager
If management fails to understand the risk in these interfacing areas and drives the procedural and process detail too low the organizations will strangle each other with interface control issues and efficiency will suffer.
