I recently read again The E-Myth Revisited: Why Most Small Businesses Don't Work and What to Do About It.
This is a great book, a little bit romanced to get its point, american speakers are the best story tellers.
The idea is :
The product of the entrepreneur is a business.
The product of the manager is scalability.
The product of the technician is the commodity. (a book, a service, a software)
These are the three main personas in a company, and the company is as good as its weakest link.
If you are these three persona at the same time, any imbalance cause pain.
Too much of the technician, and you become your business' slave. You are not working for you, you are working so your business can survive another day.
A business should help its founder to survive... not the other way around.
Too much of the manager, nothing get done, everything become a process and the company becomes too heavy to adapt any change in the environment.
Too much of the entrepreneur, and nothing ship because there is always an idea to improve, and a new feature to add.
The entrepreneur makes the whole business appealing so someone else can buy it. (Either in share, in patent, or in franchise)
The manager makes sure that the business can scale easily, order and predictability are just a mean to this end.
The technician make what the customer is buying, the commodity.
Each of these three personas has their own goal, by hearing them, we can channel them on the same path for our own growth.
