Business process re-engineering (BPR)

• The fundamental rethinking
• and radical redesign
• of business processes
• to achieve dramatic improvements
• in critical, contemporary measures of
  performance,
• such as cost, quality, service, and speed
• (Hammer Champy, 1993)

5
Features of BPR 1

• Re-engineering determines
• what an organisation should do
• how it should do it
• what the concerns should be ...
• NOT what they currently are
• Radical change NOT gradual change

6
The Euphoria

• Dont automate, obliterate
• Sweep away job definitions
• Break loose from outmoded thinking
• Conventional change is like rearranging the deck
  chairs on the Titanic
• The solution to bloated, clumsy, rigid,
  sluggish, non-competitive, uncreative, disdainful
  of their customers needs, and losing money
  (Hammer and Champy)

BPR covers

• jobs
• structure
• values
• beliefs
• management
• measurement systems
• in addition to process redesign

8
Features of BPR 2

• IT seen as an important enabler of change NOT a
  key driver of change

9
Process Innovation (Davenport 1993)

• Develop the business vision and process
  objectives
• Identify the processes to be redesigned
• Understand and measure the existing process
• Identify the IT levers
• Design and build a prototype of the new process
