Motion – any movement that takes time and / or effort that does not directly add value. In this series titled “The 8 Lean Wastes and Their Potentially Disastrous Effects”, we examine case studies for when companies, government organizations, or entire industries have allowed a specific type of waste to escalate to a disastrous effect. In this post, we review the waste of Motion to understand what causes it, how to see it, and how to eliminate it.
The 8 Wastes and Their Potentially Disastrous Effects:
In 2005, Hurricane Katrina broke the levees in New Orleans’ lower 9th ward, resulting in catastrophic flooding. Despite the desperate and obvious need for relief, local, state, and federal emergency response agencies failed to supply sufficient aide with any level of urgency. Officials deliberated, stalled, and wasted critical time deciding when, how, and rather or not to respond. An estimated 1,836 lives and $108 Billion were lost due to the flooding. It’s difficult to quantify exactly how much of this loss can be attributed to the poor emergency response; but we can all agree that the amount of time and effort wasted prior to providing aide was a complete disaster in itself.
During the event, aide, although debatably insufficient, began to arrive for some affected by the flood. Many people have fled the northern gulf coast to cities like Houston, Nashville, and others around the US – never to return home. Programs to help Katrina victims to resettle elsewhere sprang up around the United States. After Katrina, FEMA was granted authority and tools to respond to crisis more urgently, including the Post-Katrina Emergency Response Act (PKERA). This new system was tested a few years later during Hurricane Sandy and the results were markedly improved.
All major studies concluded that the US Army Core of Engineers (USACE) were primarily responsible for the failing levees. However, they were granted immunity under the Flood Control Act of 1928. The USACE cited budgetary constraints for installing the insufficient levee system. This is one case where saving perhaps a few million dollars ending up costing thousands of lives and hundreds of billions of dollars in the end.
For more details on this case study, check out the Wikipedia article at the following link:
Motion waste occurs in abundance in just about any manufacturing or supply chain operation. Anything from reaching across a table to grab the next unit to shuffling pallets in the warehouse to get everything to fit can be considered motion waste. It is nearly impossible to eliminate all motion waste but it can definitely be reduced greatly. Reducing motion waste reduces process cycle times resulting in an increase in throughput. The best way to measure motion waste is the perform a detailed breakdown of the work needed to execute a process called a Time & Motion Study. In this case, the more granular, the better. For example, a time & motion study output might look like this:
Observe how over 30% of the time spent processing this unit was wasted motion. This type of waste can be reduced by identifying the waste from time & motion studies on critical process steps and optimizing workstation design to increase efficiency. This method allows you to optimize for efficiency within a process step at a very technical and granular level; but can yield tremendous cost and lead time savings if you can increase throughput at the bottleneck step by 30%.
Impruver also helps you see motion waste. Motion waste reduces throughput, increases operating costs, and lengthens lead times. Impruver helps to motivate employees to reduce motion waste by highlighting achievements such as Raising the Bar (outperforming the previous standard). When motion waste is reduced, it can lead to the previously established standard being exceeded, at which time best-practices and operator recognition is distributed across your manufacturing network. This helps others to make progress toward creating breakthroughs in performance as well.
