Introduction to Lean Waste
Lean management focuses on eliminating waste to improve overall customer value. The concept of waste in Lean is broadly categorized into 8 types, famously known by the acronyms "TIM WOODS" for manufacturing environments and "DOWNTIME" in a more general context. These acronyms help in remembering the types of wastes businesses should look out for: Transport, Inventory, Motion, Waiting, Overproduction, Overprocessing, Defects, Skills (underutilization). Understanding and identifying these wastes are the first steps towards creating more efficient, productive, and cost-effective processes.
Defects
Products or processes that fail quality standards, leading to rework or scrap.
Overproduction
Producing more than what is needed, leading to excess inventory and resources.
Waiting
Idle time resulting when employees or machinery wait for the next step in a process.
Non-Utilized Talent
Underusing people’s talents, skills, and knowledge.
Transportation
Unnecessary movement of products or materials, which adds no value to the product.
Inventory
Excess products and materials not being processed.
Motion
Unnecessary movements by people that don’t add value to the product.
Excess Processing
Doing more work than what is required by the customer, leading to wasted time and resources.
