You would be surprised how far you can get with consistent pressure and time. Small iterative changes. It works for practices/culture as well as technology.

There is never some big meeting where everyone decides that 'operations are going to change! From now on we are going to X!" Well sometimes there are such meetings, but often means merely adding another demand. Like a new years resolution, it is a strongly voiced command for better results, with no real changes behind it.

Real improvement is about adding practices and habits. Starting with the most needed/highest payoff items and gradually building on them.
