I'm a believer that the best way to make sure a job is done well is to build quality into every system and process. That prevents most problems from ever occurring. An inspection to catch mistakes after its all done is good, but it's much better (and cheaper and faster) to not make those mistakes in the first place.
This cartoon reminds me of Sunday dinner at my house. Most Sunday afternoons, all 17 of our kids and grandkids gather at our house for dinner. As the little ones play, the adults assemble in the kitchen to prepare the meal. I personally provide so much "quality control" while we're cooking that sometimes I'm no longer hungry by the time the meal's finally ready.
I thought it would be fun to show a high schooler proudly delivering a fully "quality inspected" sandwich to his customer. At least he can personally attest that it is delicious.
