Reason you give for not shipping shit
We have a bunch of technical debt we have to work resolve before we can ship X new feature
A silly but effective analogy to explain refactoring to business people.
Developer: "We need to refactor the legacy auth module, which is a dependency for most of our new modules."
Business Guy: "... wat."
Developer: "Some of our early code was debt-financed. That senior debt has preference until we pay it off."
Business Guy: "Oh, I totally get it now. Why didn't you just say that?"
Technical debt is a metaphor referring to the eventual consequences of consistently pushing shitty code that works in the short term, but fucks you up in the long term.
Justin's team at Hooli spent the entire week accounting for their technical debt.
