Question - A forensic expert walks into a room with a bunch of dead Six Sigma Black Belts who show no visible signs of injury. What's the first thing he should check for? Answer: Poisson distribution.

Earlier it use to be 7 waste Now Made as 8 waste in nature It come under MUDA of Japanese Term conversion as "Waste" To remember the 8 Wastes, you can use the acronym, “DOWNTIME.” •Defects – Products or services that are out of specification that require resources to correct. •Overproduction – Producing too much of a product before it is ready to be sold. •Waiting – Waiting for the previous step in the process to complete. •Non-Utilized Talent – Employees that are not effectively engaged in the process •Transportation – Transporting items or information that is not required to perform the process from one location to another. •Inventory – Inventory or information that is sitting idle (not being processed). •Motion – People, information or equipment making unnecessary motion due to work space layout, ergonomic issues or searching for misplaced items. •Extra Processing – Performing any activity that is not necessary to produce a functioning product or service. With respect to the above Question We can put to Good Use In organisation by ways such as Alert or Warnings , Reduce or try to Eliminate depending upon the Nature of waste. Considering Mechanical System 1) We can reduce or eliminate Defects by control methods including Mistake proofing /Poke yoke 2) we can reduce or eliminate Overproduction by changing from PUSH system to Pull System , Made to Stoke to Made to order , Reverse Kanban ordering and super market. 3)Waiting is tricky but need to Reduce by methods such as SMED (single minute exchange of Dies),Line Balancing, controlled Inventory /safety stock( again a waste if inventory). 4) Transportation by using conveyors instead of human motions , plant layout reorganization from process to product layout , cell systems etc...re-planing activity to have less motion and movements , using ergonomic design of Work benches and assembly lines 5) Inventory Complete elimination may not be possible but reduction should be made using methods such as batch production , pull Kanban and made to order etc... 6)Motion here motion is for human and transportation is for Products so motion can be worked out with Ergonomic study , moving assembly line (car assembly line), usage of jigs for manufacturing and assembly, usage of Power-tools and automation. 7) Extra processing / over processing this needs to be addressed by working on VA and NVA (value added and Non Value added ) study . eliminating process depending on functional need of the products rather than aesthetics. controlled working environment rather than safety stock ( working towards the mean rater than UCL )which may sometime process to rework ( myth of keeping stock to rework rather than scrap / salvage allowance ) the 8th waste Talent utilization is done by considering the views of all members and allocating roles and responsibility depending upon talent and behavior rather than hierarchy and influential / favoritism , utilizing everyone in stand up meetings andsolving problems as a team
