Over-processing? Rework? Inventory? Overproduction? Transportation? Waiting? Motion? Eliminating waste can save you time and money. Have you ever heard the saying “If you don’t have time, when will you have time to do it over”? In the literal sense we may not take that to heart, but when you think about it, if you do a bad job and have to redo something you have wasted the initial time to do the job plus the additional time to do the job again.
Depending on what you are doing, for example, if you are building a wooden framed structure and have to rebuild it you have two wasteful points. You have the initial incorrect build, then 1) time to demolish or disassembly of the incorrect structure and 2) rebuild for the 2nd time. So instead of one build you have a build - tear down - and build. What helps here? Verification of the process against the original specifications and quality control. Continuous monitoring throughout the projects lifecycle helps to minimize rework.
There are 7 Types of Waste (muda) defined by Taiicho Ohno (Toyota executive 1912-1990)
1. Waste caused by product defects
2. The waste caused by overproduction
3. Waste caused by waiting for the next step in the process
4. Waste caused by transportation
5. Waste caused by movement within the factory or between process steps
6. Waste during processing
7. Waste due to inventory
