Defects and Waste
Six Sigma defects result from process failures, causing financial losses and damage to reputation
Waste includes unnecessary time, labor, or material in processes
- Seven common types of waste (muda) include overproduction, correction, inventory, motion, conveyance, over-processing, and waiting
Inventory: Accumulation of materials before a process step; reduce batch sizes
Motion: Unnecessary employee movements during a process; streamline processes
Correction: Reworking defective work; root causes should be addressed
Conveyance: Unnecessary movement of outputs or resources; analyze and eliminate
Overproduction: Producing too much too soon; planning is essential
Lean principles focus on planning, process changes, layout adjustments, and addressing root causes to eliminate waste in various forms
Investing more resources than valued by the customer
Idle time in a process for machinery or people
Sort, Straighten, Shine, Standardize, Sustain
Just-in-Time Manufacturing(JIT)
Produce output just in time, minimizing waste
