Motion: going nowhere fast
Unnecessary Motion's Manufacturing Golden Days
In contrast to transportation, which refers to damage to products and transaction costs associated with moving them, motion refers to the damage that the production process inflicts on the entity that creates the product, either over time (wear and tear for equipment and repetitive strain injuries for workers) or during discrete events (accidents that damage equipment and/or injure workers). Motion increased transactional costs and created Delay.
Unnecessary Motion in Software
Motion found new meaning in software development with task switching and should taps. He is able to create massive transaction costs when people we forced to switch from one task to another. In some cases, the cost could be as high as 40% of their productivity…this was far better than wear and tear on equipment that could easily be repaired. Motioned plays on a fear that if our expensive "resources" are not close to 100% utilized, then we have an inefficient work process. Therefore professional project managers spend hours scheduling "resources" to maximise utilization and as a side effect, increasing the waste created by unnecessary motion.
Unnecessary Motion's Vulnerability
Single piece flow is Unnecessary Motion's mortal enemy. A focus on "getting something done" rather than focusing on utilization eliminates Unnecessary Motion.
