Lean strategies
•The aims of a leanstrategyare to do every operation using less of each resource –people, space, stock, equipment, time, and so on.
•It organises the efficient flow of materials to eliminate waste, give the shortest lead time, minimum stocks and minimum total cost.
“All organisations are at least 50% waste –waste people, waste effort, waste space and waste time”
Robert Townsend
Lean: 5 main principles
•Value–designing a product that has value from a customer’s perspective
•Value stream –designing the best process to make the product
•Value flow –managing the flow of materials through the supply chain
•Pull–only making products when there is customer demand
•Aim of perfection –looking for continuous improvements to get closer to the aim of perfect operations.
Waste identified by Toyota
•Quality–that is too poor to satisfy customers (either external or internal).
•Wrong production level or capacity –making products, or having capacity, that is not currently needed.
•Poor process –having unnecessary, too complicated or time-consuming operations.
•Waiting–for operations to start or finish, for materials to arrive, for equipment to be repaired, and so on.
•Movement–with products making unnecessary, long, or inconvenient movements during operations.
•Stock–holding too much stock, increasing complexity and raising costs.
