Reducing Waste Flashcards
What is waste minimisation?
It’s reducing the amount of resources (physical, capital, human, time) that are misused or discarded by the business during operations.
Why do we aim to minimise waste?
This is done as wastes costs money and impact profitability and reduces productivity, making it harder to meet business objectives.
What is lean management?
It is a business wide approach that aims to eliminate waste and inefficiencies in operations.
It aims to maximise customer calue through continuous improvement by eliminating all aspects that do not add value to the end product.
Doesn’t reduce quality.
What are the 4 principlles of lean management?
- 7 sources of waste
- Pull
- One-piece flow
- Zero defect
What are generic waste management strategies?
Reduce-decrease excess amount of products, labour or time discarded during production.
Reuse-making use of item that would have outherwise been discarded.
Recycle-transform items that would have been otherwise discarded.
What are the 7 sources of waste (TIM)?
Transportation-inefficient movement of materials of product
Inventory-supplies that are not used or lay idle for a long time
Motion-excess movement of resources/product during production
What is Pull?
It the the production responding to customer demand rather than producing and then looking for buyers. This minimises overproduction and produces based on actual demand.
These products are made-to-order, preventing unwanted products from being produces and then discarded.
What is the one-piece flow
It is the a single product moving through all the stages of production one at a time, reducing the time spent at each stage waiting.
(Imagine a continuously moving conveyor belt)
What are the 7 sources of waste (WOOD)?
Wait time-lag time between processes or production/distribution
Overproduction-producing more than customer demand
Over-processing-performing processes that fdo not add value
Defect-error wither need to be fixed or discarded
What is zero defects?
It is preventing defects from occuring in the production process. This is a whole business approach (like TQM) where there is an ongoing attitude of preventing defects from occuring and improving the final product.
