8 wastes of lean training presentation
The 8 wastes of lean are the eight kinds of activity that use time and resources without adding value for the customer: transport, inventory, motion, waiting, overproduction, overprocessing, defects and unused skills. This free deck teaches a team to see them in about 30 minutes. Its 17 editable slides cover value and waste, where the list comes from, each waste with examples and a question to ask, muda, mura and muri, how to run a waste walk, an illustrative example, the common mistakes, a spot-the-waste activity and four check questions with answers. Every slide has speaker notes.

How to run it
Running the session
- 1
Prepare
Read the speaker notes once and swap the illustrative example for one from your own area if you have it. Print the PDF if people like a handout.

Present
The slides take about 15 minutes. Every slide has notes, so you can talk from them rather than read the slide.

Check and follow up
Ask the check questions before showing the answers, then agree one next step with an owner and a date before people leave.
The check questions
- 1. What does TIMWOODS stand for?
- Transport, inventory, motion, waiting, overproduction, overprocessing, defects and unused skills.
- 2. Why is overproduction called the worst waste?
- It creates other wastes, such as inventory, transport and waiting, and it hides problems until late.
- 3. What is the difference between mura and muri?
- Mura is unevenness in the workload. Muri is overburden on people or machines.
- 4. Is all non-value-added work waste to remove right away?
- No. Necessary non-value-added work, such as some inspections and required records, stays for now but should be reduced.
Templates and guides to go with it
- Waste walk checklist (TIMWOODS)32 things to look for across the eight wastes, with where and how much, and a findings log with dot votes, owners and dates.
- Spaghetti diagram templateSquared paper to trace every trip, a tally of trips and distance, and a before and after comparison.
- Lead time worksheetProduction lead time from the inventory waiting at each step, value-added time and process cycle efficiency, plus an order traced from order to delivery.
- Time study sheetTime each element over 10 cycles and work out the average, lowest repeatable and standard time. Excel does the sums.
