Vocabulary matters in business. One of the problems many large companies face is that bureaucrats have won the vocabulary war. They want us to believe that the opposite of simple is advanced and that to simplify means to dumb down, to cut corners, to somehow be less advanced.
But for our purposes, the opposite of simple is complex. To simplify is to improve systems and processes by making them more straightforward. Importantly, simplification is also a way to redeploy. Streamlining something or making it easier to do allows you to free up resources and move them elsewhere to support other priorities.
