In a JIT supply chain, reliable suppliers will reduce supply uncertainty and make the supply chain more effective, therefore supplier selection is crucial. However, Purchasing in JIT environment is different and therefore it requires a slightly different mindset for selecting suppliers who can survive in JIT Supply Chain long term. Researchers1 suggested that the selection and evaluation of supplier’s ability to delivery in JIT Supply Chain should be based upon the following factors:

 

JIT Supply Chain- Quantitative & Qualitative Supplier Selection Factors

1.      Delivery of a Quality Product

2.     Delivery On-Time.

3.     Frequent Deliveries.

4.     Delivery in Small Quantities.

5.     Delivery of Exact Quantities.

6.     Supplier’s Management Policy and Philosophy

7.     A Willingness and Openness to Share Data and Information

8.     Attitude towards Partnership

9.     Willingness to Undertake Continuous Improvement

10.   Desire to Develop New Products

11.   Ease of Communication at All Levels

 

Hall (1983) suggested capacity and willingness to improve as additional criteria to the above list.

Carr and Truesdale (1992) stated that Nissan’s supplier selection team visits supplier factories frequently. They evaluate delivery reliability similar to those above. They evaluate products from design and development through to the manufacturing processes.

 

The Nissan team also looked at planning, operation, tidiness, appearance of workshop, working situation and professionalism. For professionalism they looked at engineering management attitude, the number of engineers employed, how they are structured, their technical capability and their influence within the organisation. Supplier’s location and market size is of less importance to Nissan.

 

Aleo (1992) described the supplier selection procedures of Kodak. A selection team is formed by Kodak consisting of multi-discipline specialists. They developed a suitable decision matrix for the particular product under the evaluation. The suppliers are ranked numerically according to their ability to meet Kodak’s programmed needs.

The selection process started with a review of current documentation pertaining to their suppliers. A comparison of supplier capabilities is then recorded in the decision matrix. The team review all historical data, quality, delivery and inspection procedures. Kodak maintained an open communication with its suppliers in the area of quality improvement and advised suppliers who failed to achieve the expected quality standards. A follow-up inspection is undertaken to ensure that the agreed changes have been carried out.

 

Southey (1993) described the current practices of supplier appraisal as more encompassing than before. The appraisal can be divided into two areas namely quantitative and qualitative. Quantitative includes location, financial position, facilities and capacities, technical capability and standards of quality, whereas Qualitative consists of items 6-11 in list above.

 

Southey (1993) also suggested other general evaluation criteria when there are numerous suppliers, for example, comparison with the level and quality of similar suppliers, supplier’s relationship with competitors, supplier’s track record and potential for future improvements to sustain JIT Supply Chain.

 

In JIT Supply Chain, ‘Lean supply’ requires additional supplier selection criteria. Particularly in the sense of sourcing parts close to the points of manufacture so as to keep logistic cost to a minimum. The supplier must be ready to provide a service ‘locally’ wherever the manufacturer requires it in the world. As lean production develops globally, manufacturers tend to find local suppliers prepared to compete to improve leanness.

 

Summary:

There has been huge amount of research done to identify suitable supplier selection criteria. The above mentioned 11 quantitative and qualitative factors are just one aspect which has been identified with keeping JIT Supply Chain only in mind.
