“Knowledge has to be improved, challenged, and increased constantly, or it vanishes.”

“We all have a vast number of areas in which we have no talent or skill and little chance of becoming even mediocre. In those areas a knowledge workers should not take on work, jobs and assignments. It takes far more energy to improve from incompetence to mediocrity than it takes to improve from first-rate performance to excellence.”

“What's measured improves”

“A manager is responsible for the application and performance of knowledge. ”

“Business has only two functions — marketing and innovation.”

“The knowledge that we consider knowledge proves itself in action. What we now mean by knowledge is information in action, information focused on results.”

“The people who work within these industries or public services know that there are basic flaws. But they are almost forced to ignore them and to concentrate instead on patching here, improving there, fighting the fire or caulking that crack. They are thus unable to take the innovation seriously, let alone to try to compete with it. They do not, as a rule, even notice it until it has grown so big as to encroach on their industry or service, by which time it has become irreversible. In the meantime, the innovators have the field to themselves.”
