Paradigm definitions • Agility • Agility means using market knowledge and a virtual corporation to exploit profitable opportunities in a volatilemarket. • Leanness • Leanness means developing a value stream to eliminate all waste, including time, and to ensure a level schedule. • Decoupling point • Decoupling point separates the part of the organization oriented towards customer orders from the part of the organization based on planning • Buffer stock, stock holding point • It depends on longest lead time an end-user is prepared to tolerate and the point at which variability in product demand dominates. Manufacturing Automation & Integration Lab
Characteristics of paradigms • Use of market knowledge • All business in any supply chain must focus on the end-user. • Integrated supply chain • The coal of an integrated supply chin is to remove all boundaries to ease the flow of material, cash, resources and information • Lead time compression • “muda” Eliminate Information Delay Manufacturing Automation & Integration Lab
