Jamie Claar Nyron Gopeesingh Antonio Roig Sandra Wenning Amy Wong Jonathan Wong Robert Wort General Electric TSBO Purchasing and Just-in-time
Objectives • Definition of technology “Technology refers to the work processes, techniques, machines and actions used to transform organisational inputs (materials, information, ideas) into outputs (products and services).” (R J Schonberger “World Class Manufacturing in the Next Decade,“ 1996.) • How changes in purchasing technologies affect structure and culture? • How JIT affects the relationships with Suppliers and Customers? • Benefits and drawbacks of JIT • Recommendations and Implementation • What structural and cultural changes are needed?
Overview of TSBO • General Electric TSBO produces railway locomotives and electric drive motors, rail transit vehicles, and oil and other drilling equipments. • TSBO experienced a severe decline in locomotive market from 1970 through 1976: • In 1976 no order were placed for locomotives. • Low quality supplies. • GE agreed to invest US$300m to TSBO in a expansion program in 1977. • In 1979, TSBO implemented an MRP program. • Resulted in the first-ever Materials Operating plan. • Consolidation of purchasing in one unit.. • Created PACE, SOS and DSS programs. • In 1981, TSBO analysed the alternative of implementing JIT • To further improve quality and, • Further reduce costs… • But the currently DSS program conflicts with JIT doctrine.
Small batch-unit production Purchasing: Mechanistic structure Sequential purchasing interdependence Adversarial with suppliers Individualism Short-term contract focused Current situation vs. Introduction of new technology Structure “Just In Time” Culture Technology First-ever Materials Operating plan MRP system operating by Dec 1979 Moving to FMS (Grove City) “New era for Purchasing at TSBO” : PACE, SOS, DSS Relationship with many suppliers
JIT concept: Classic diagram • JIT Definition includes: • Recognised as a technique / philosophy / way of working. • Items are purchased and only move through the production line as and when they are needed. • Associated with the Toyota motor company, JIT was initially introduced as part of the "Toyota Production System." • Now recognised as a key part of “Lean Manufacturing.” Company Sea of inventory Rocks - the problems by the sea of inventory If we reduce the inventory level then the rocks become exposed, as below. Company Now the company can see the rocks (problems) and hopefully avoids (solves) them before it runs aground! Source: J. E. Beasley (Faculty member of Imperial College)
Cultural implications of JIT at TSBO - Suppliers • TSBO must change the way it views suppliers: • Increasing openness – information flows • A spirit of partnership – mutual benefits • The increasing importance of trust • Vendor “co-destiny”
Cultural Implications within TSBO plant • Participative management, task ownership • Commitment to organisational goals • A team-oriented approach • McGregor’s Theory X and Theory Y • Increased responsibility for shop-floor workers • Initiative fatigue
Structural Implications within Material Management • A significant change in job content • From tactical to strategic • Reduction in headcount • Importance of boundary-spanning
Structural Implications for TSBO plant • Optimal fit between structure and workflow technology • Current organisation design fits nature of production flow • Relationships between elements of organisation must be examined

Significant cultural differences must be taken into account… • In 1981, William Ouchi, author of Theory Z: How American Management Can Meet the Japanese Challenge, formed Theory Z • Combining American and Japanese managing practices in organizations • Many differences in style of management between the two countries • Japanese believe in lifetime employment • Secure in their positions • Japanese believe in trust • You should always be loyal to everyone in your company • Including the people who supply your company with supplies
How will the JIT system affect relationships with suppliers? • Long-term, contractual relationships, emphasising trust, partnership, openness, co-operation • From multiple suppliers assuring security of supply to few suppliers, or single-source • Reduction in paper work, as fewer purchase orders and invoices are raised • Longer-term commitment gives security to suppliers • Increase demands on suppliers – quality and on-time delivery are essential
How will the JIT system affect relationships with customers? • Customer demand will be the main driver of the manufacturing plan. • The JIT approach may be extended – anticipate future customer demand to assist production planning • Improved product quality to increase customer retention. • Savings from the JIT cost reduction may allow TSBO to pass cost savings on to customer
Benefits of Just In Time • Reduce costs through lower inventory and storage space • Reduction in manufacturing cycle times • Reduce material handling • Improve product quality • High productivity through worker involvement and higher work skills • Stable and reliable supplier relationships with information sharing
Risks and drawbacks of JIT at TSBO • Work stoppage due to possible material shortage or poor quality. • Cultural differences between American and Japanese supplier relationships. • High cost of frequent supplier distribution. • Contradicts with current purchasing practice (DSS program) and competitive bidding process. • Possible ethical and legal problems arising from too much familiarity with vendors. (e.g. Price Fixing) • Lack of support from employees.
