Lean: Identifying Waste Toyota Production Systems Lab Grade K-5
| 2 Identifying Waste Identifying waste is the first thing that Industrial Engineers do when we look for things to improve on. Waste is everywhere! It is easy to find when you know what to look for! By identifying waste, we identify the problem and then produce a solution to fix the problem. That is what Lean is all about!!
| 3 The 7 Types of Waste There are 7 different types of waste. It can be hard to keep track of them all, so we are going to review them with our friend Tim Wood!
| 4 The 7 Types of Waste with Tim Wood Tim Wood was a wood carver and had a shop in the forest where he cut trees down and used the wood to make pretty things to sell. He loved his job but noticed a lot of waste in his work. Here is what he found.
| 5 Types of Waste Tim Wood Found Transportation Tim drives back and forth to his shop 5 times a day to make deliveries. Inventory Tim loves carving wood and makes soooo many carvings that he has to pile them up in every corner of his shop! Motion Tim runs around all day and never sits still because all of his tools are in different places. Waiting Tim plants new trees at the same time so he has to wait years until they are ready to be cut down.
| 6 Types of Waste Tim Wood Found Overproduction Tim only sells 10 carvings a day, but he makes 20 just for fun. Over Processing Every time someone asks him to make a specific carving, he has them fill out 5 different forms instead of one. Downtime Tim has a machine he used to polish his tools, but the machine tends to break down often slowing down his work.
