Consistency

I'm modifying some circuit breaker drawings for work, and the existing drawings are not consistent with each other. Some show just the model number of the breaker; others show just the amperage of the breaker; others show both; and others show none of this information at all. Our typical practice when modifying drawings is to follow the existing convention of that drawing. So I did. However, my reviewer was frustrated that I had not made the decision to deviate from following the existing convention of the drawing; he had wanted me to show both pieces of information on all the drawings, regardless of what was there before. Although everyone else in my group (including my supervisor) stepped into the conversation and told him it was typical to follow the existing drawing convention and that other drawings showed that information anyway, the reviewer was not satisfied, and began lecturing about consistency:

R: It's like Starbucks.

(sidebar.....nuclear engineering is nothing like Starbucks)

R: I can go to any Starbucks and it's always the same coffee no matter what. Because they are consistent. They found a way that works and they stick to it no matter what. Consistency. That's what matters. When I get coffee at Starbucks, whether it was a year ago, or today, or 5 years from now, I know it's going to taste the same. Because their coffee is always consistent. That's why they are still in business and that's why they are so popular. Whether I get my coffee at a Starbucks here in the city, or near my house, or in Florida when I visit my daughter, I can always be sure that it will taste the same everywhere I go, no matter when. Because they know consistency!

C: You get your coffee at Starbucks?

P: You should go to Dunkin Donuts. It's much better, and cheaper too.

R: Oh no. I don't drink coffee.
