Contribution of W. Edwards Deming in the field of Supply chain management
W. Edwards Deming, has played a significant in developing the foundations of quality in the management sector. He was one of those leaders who propagated the Quality philosophy.
He has given an immense contribution in the development of Total Quality management concept. His one of the most famous and well acclaimed work has been observed in his book “Out of the crisis” which discussed the importance of quality systems in the progress and development of business (Deming, 1986).
He also developed 14 points on management which are more commonly known as “Deming’s 14 points of management”. These points have revolutionized the field of management by inculcating quality within the system and establishing its relation with the economic production and supply throughout the chain. Few of the points from his work that directly impacted the pattern and style of management across the supply chain are as follows:
• Develop consistency of purpose in improving the product, service and operations throughout the chain that would help in developing a competitive and efficient supply across the chain.
• Avoid the need of mass inspections by developing a quality product right from the beginning of the chain.
• Stay loyal to one supplier by widening the scope of the business from mere concentration on the prices across the chain.
• Improve leadership and training among the members of the supply chain and involve active participation of each one of them. Break the barriers among the members of the chain and educate them in developing and maintaining high quality of the product throughout the supply chain.
Dr. Deming has made great contributions in the development of quality management methods across the supply chain (Loucka, 2006). He has immensely contributed in improving the economy of Japan, where he used to teach and educate top management and engineers from beginning from the year 1950.
Contribution of Joseph M. Juran in the field of Supply chain management
Joseph M. Juran, has been a well-known researcher on the subject of quality management in the supply chain. He has developed the importance of quality to develop and improve business across the supply chain. He has inculcated the use of planning in achieving and maintaining quality in the supply chain.
He had examined the operation of various departments in the supply chain and developed a relationship among them to observe excellence in their working. He has developed a well- acclaimed theory known as “Quality Trilogy” which has focussed on three elements that contribute towards the quality management throughout the supply chain. These theory has also been called as “The Juran Trilogy” (Foster, 2007). The three elements developed in the trilogy are:
• Planning: He developed that the forces operating across the supply chain should be encouraged and involved in producing products and services that is required by the customers. This should be inculcated with proper planning of quality and operations in the management of supply chain.
• Control: Juran also stated that various measures and inspection has to be done to ensure the quality of the product. According to him, analysing the need and estimating the quantity of production is also involved in controlling the supply chain management.
• Improvement: He developed that after analysing and identifying the elements that require monitoring or changes needs to be discussed by the members of the supply chain and actions has to be taken on that to ensure the proper growth of business from one project to another across the supply chain.
He has discussed the above elements in his book of “Quality, planning and analysis” which served as a basis of studying and understanding the importance of planning and taking related actions in the supply chain (Juran & Gryna, Quality planning and analysis , 1980).
He has also developed a quality handbook which is more commonly known as “Juran’s quality handbook” where he has discussed about quality leadership, defined the roles of the upper managers in the chain and developed means for the upper managers to ensure their success in managing business across the supply chain (Juran & De Feo, Juran’s quality handbook, 2010).
