Introduction. In the field of quality management, a number of distinctive "philosophies" have emerged. These have been closely associated with a relatively small number of celebrated "gurus".
As the demands on purchasing become more intense, it is necessary to improve the variety and effectiveness of the approaches and techniques utilized in supplier management activities.
We shall present a review of some of the approaches developed by the gurus and then illustrate with practical examples how they can be used to generate significant improvements in value delivery for the customer.
We shall also describe the benefits that accrue to suppliers when exposed to such progressive methods of approach.
Objectives. The objectives of this presentation are:
The Need. As purchasing increases its influence in organizational terms, the strategic importance of source selection and continuing supplier management becomes significant. We will present an overview of some of these "guru" approaches. The application of these techniques in purchasing scenarios will then be described.
We believe it is time that individuals form the purchasing world are accorded some of the accolades associated with the Quality gurus. In recent years, Mr. Lopez has probably been the most talked about purchasing "guru", not always with the most favorable impression.
Review of "Gurus" and Techniques. We have selected a number of topics from the following:
1. W. Edwards Deming:
Quality is the responsibility of everyone.
There is always a way of improving.
Prevention is better than cure; consider the process rather than the products.
Adopt a balanced approach; do not focus totally on price or technical elegance.
Provide training in statistical techniques.
Remember the Deming Cycle - PDCA -
2. Joseph Juran
Concept of internal customers and suppliers
The Quality Trilogy
Total cost of quality
3. Phil Crosby
Concept of zero defects and setting the target at 100%
Price of Non Conformance"
The importance of communication (including listening)
4. Armand Feigenbaum
The "hidden factory, the proportion of capacity required for corrective action
Right first time
5. Kaoru Ishikawa:
The concept of "Quality Circles"
Statistical Process Control
The seven tools (see later)
6. David Garvin:
Concept of Quality Strategy
The eight Dimensions (which offer opportunities for competitive advantage)
7. Shigeo Shingo:
Just in Time
Pokayoke devices (idiot proof!)
8. Genichi Taguchi:
Quality through design
Concepts of "loss function", typified by the following: (graphic not available in text-only version of this paper)
Tools and Techniques. From the gurus, there are a number of tools and techniques which have proved enormously useful in the contest of supplier management. We particularly command the adaptation of the 7 tools of quality (Ishikawa).
Examples. We shall present a range of examples of how these approaches and tools have been adopted and used successfully in purchasing situations. These practical scenarios will demonstrate the benefits to be gained from adopting external management techniques for purchasing related activity.
Summary. A selection of gurus and some of their techniques have been reviewed. Case studies showing their successful application in purchasing and supplier management situations have been presented.
We recommend that purchasing professionals continue to bring outside thinking and practices into their working lives.
