All of these things take time away from production.
Friday, June 5, Lean Software Development: The situation was eerily familiar.
A year earlier a chip had cracked off of my tooth as I ate a pizza in Lima, the first stop of a ten week trip to South America.
I ate gingerly during the rest of the trip, worried that the tooth would crack further. Luckily I made it back home with no pain and little additional damage. Once there, it took three days to get a dentist appointment. The dentist made an impression of the gap in my tooth and fashioned a temporary crown.
Two weeks after we arrived home, my tooth was fixed. We were scheduled to be in Cape Town for only two days. How was Tom going to get a crown replaced in two days?
A small committee formed. Someone did a phone search; apparently the Waterfront was a good place to find dentists. A call was made. Do you want someone to walk you over? Half way through the talk, I saw Tom return and signal that all was well.
Instead of making a temporary crown, he used a camera to take images of the broken tooth and adjacent teeth. The results were combined into a 3D model of the crown to which the dentist made a few adjustments. With the push of a button, instructions to make the crown were loaded into the machine.
Cutters whirled and water squirted to keep the ceramic cool. Ten minutes later the crown was ready to cement in place. Ninety minutes after he arrived that afternoon and eight hours after the incident, Tom walked out of the dental office with a new permanent crown.
It cost approximately the same amount as my crown had cost a year earlier. In fact, a focus on resource efficiency will almost always destroy overall efficiency, the authors contend, because fully utilized machines and people create huge traffic jams, which end up creating a lot of extra work.
