  1. BUSINESS PROCESS REENGINEERING “An organizational make-over” “Reengineering is new, and it has to be done.” Peter F. Drucker

  2. BUSINESS PROCESS REENGINEERING • The search for, and implementation of, radical change in business processes to achieve breakthrough results • Synonyms: business process redesign, business transformation, process innovation, business reinvention, change integration • Starting point: clean sheet of paper

  3. BUSINESS PROCESS REENGINEERING • Start from the future and work backwards • BPR is not easy - serious work • BPR is not free - financial & cultural • BPR often driven by fear and greed • Change is a “struggle”; BPR is a “war”

  4. BPR: LESSONS LEARNED • Get the strategy straight first • Lead from the top • Create a sense of urgency • Design from the outside in (customer) • Combine top-down & bottom-up efforts

  5.

Little Inc.
