What is the definition of Improvement Engineering?

Improvement engineering is like the secret sauce for making your life a tad more... efficient, but not quite as satisfying as a perfectly ripe banana. It's the art of tweaking and optimizing systems, processes, or even your daily routine to make everything run smoother, faster, and a whole lot less annoying. Think of it as the high-fidelity version of 'ake it work' but with a side of 'I wish I could make it work without effort!'

Example sentence: "After years of improvement engineering, our coffee machine finally stopped making burnt creamer, but now it only makes the same burnt creamer it's been making since the day we first bought it."
