This doesn't need a lot of words, but it's important to address.
The idea of lean (project management, process, startup) is not equal to less.
It's trendy to talk about lean, but most people don't really understand it.
People say they want a lean process, but they really want a cheap process or a fast process. While lean can reduce costs and speed up delivery, making something cheap doesn't make lean. Cheap is just cheap. Fast is fast.
Lean is great and helpful and awesome. But let's stop using the word "lean" when we really just want cheap and fast.
