During my LEAN Six Sigma studies, this was one of the key tools which I really liked. It can bring insight in the key process waste and quickly adds value if it is properly used during an improvement project.
I also like to see ‘TIM WOODS’ as a real person who represents this mentality and supports the continuous improvement culture. He always looks out to reduce the different types of waste, identifies opportunities to optimize processes and takes action to resolve it.
Next overview explains this acronym of the 8 types of ‘waste’ in a process:
- T = Transportation (of materials, products and goods)
- I = Inventory (of materials, products and goods)
- M = Motion (of people and machines)
- W = Waiting (of goods/services or people)
- O = Over production (of finished goods)
- O = Over processing (of materials, products and goods/services)
- D = Defects (of goods/services, which require rework))
- S = Skills underutilized (of people + in my view also for software or automation)
- Take this pile of wood and think about what waste-types you can recognize at this step?
- Or imagine what steps will take place before a consumer can buy wooden furniture and really can enjoy using it within there home?
Sometimes there are reasons why inventory is waiting to get processed, but still the methodology of LEAN Six Sigma gives an opportunity to get better insight. Also to improve and think outside-the-box, so teams can see if there are other ways or new technology to do the steps more optimized.
What type of ‘waste’ do you see in your organization? (just leave a comment)
