That one can truly manage other people is by no means adequately proven. But one can always manage oneself. - Peter Drucker

The danger is in acting on what you believe satisfies the customer. You will inevitably make wrong assumptions. Leadership should not even try to guess at the answers; it should always go to customers in a systematic quest for those answers.

It does not follow from the separation of planning and doing in the analysis of work that the planner and the doer should be two different people. It does not follow that the industrial world should be divided into two classes of people: a few who decide what is to be done, design the job, set the pace, rhythm and motions, and order others about; and the many who do what and as they are told.

For the existing enterprise, whether business or public-service institution, the controlling word in the term ‘entrepreneurial management’ is ‘entrepreneurial’. For the new venture, it is ‘management’. In the existing business, it is the existing that is the main obstacle to entrepreneurship. In the new venture, it is its absence. The new venture has an idea. It may have a product or a service. It may even have sales, and sometimes quite a substantial volume of them. It surely has costs. And it may have revenues and even profits. What it does not have is a ‘business’, a viable, operating, organized ‘present’ in which people know where they are going, what they are supposed to do, and what the results are or should be. But unless a new venture develops into a new business and makes sure of being ‘managed’, it will not survive no matter how brilliant the entrepreneurial idea, how much money it attracts, how good its products, nor even how great the demand for them.
