Background Two seminal papers on BPR were published
in 1990 by Hammer and by Davenport & Short respectively which sparked off an increased amount of interests in its concept, especially in the Western business world. Hammer M, "Re-engineering Work: Don't
Automate, Obliterate", Harvard Business Review, Vol. 90, No. 4 July/Aug, 1990, pp104-12
Davenport TH & Short JE, " The New Industrial Engineering: Information Technology and Business Process Redesign", Sloan Management Review, Vo.l 31, No. 4, Summer, 1990, pp11-27

What is BPR BPR is ultimately about rethinking the core of the
business. It was argued that the traditional functional view of an
organisation only looks at the responsibility and reporting relationships and offers little scope to measure or improve. Whereas processes have cost, time, output quality, and customer satisfaction and can offer clearer targets for measurement and improvement.
BPR is …"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 and Champy 1993)IT usually played an important role.

A bit more to BPR than processes… Andrews and Stalick (1994) suggested that
there are nine dimensions to business re-engineering. This is their model:
processstructure
technologystructure
organisationstructure
rewardstructure
measurementsystems
managementmethods
organisationalculture
politicalpower
individualbelief systems
Physical Technical Layer
Infrastructure Layer
Value Layer

The Culture WebProf. Johnson at Cranfield School of Management used a web to illustrate the relationships among different elements which shape the 'culture' of an organisation: (see also Peppard and Rowland (1995))

A typical BPR approach4 key phases: initiating a project
raise awareness of BPR, allocate key roles, understand the key processes, benchmarking
defining scope and targets analysis and re-design implementation and on-going
improvements

Process Streamlining- Harrington1. Bureaucracy elimination - removing unnecessary
administrative tasks, approvals and paperwork.2. Duplication elimination - removing identical activities
that are performed at different parts of the process.3. Value-added assessment - evaluating every activity in
the business process to determine its contribution to meeting customer requirements. Real value-added activities are the ones that the customers would pay you to do.
4. Simplification - reducing the complexity of the process.5. Process cycle-time reduction - determining ways to
compress cycle time to meet or exceed customer expectations and minimize storage costs.
6. Error proofing - making it difficult to do the activity incorrectly.

Critique of BPR - Brown & Duguid Over-emphasis on process and overlook
knowledge Only suitable for a narrow band of operations Have a ‘linear’ view of information flow, not a
true reflection of actual flow of information in an organisation which quite often requires collaborative problem solving
Assumed well defined input/output + targeted information, but in real life, ‘there are areas where making sense, interpreting, and understanding are both problematic and highly valued’
..see handout pp. 97-103 of B & D, Chapter 4
(but there is still a need to manage business processes – hence BPM activities continue)
