Paradigm definitions Agility
Agility means using market knowledge and a virtual corporation to exploit profitable opportunities in a volatile market.
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.

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

Paradigm definitions TCT(Total Cycle Time) Compression
Definition The elapsed time between customer enquiry and customer
need being met. (Philip Thomas) TBM(Time Based Management. BCG)
Reducing TCT Slashing material flow lead time Slashing information flow lead time
Pursuit of the Zeros Zero Waste + Time, materials, labor, capacity, computing
power, management effort, total cycle time, information flow
