What are the four principle styles of management?
Producer, Administrator, Entrepreneur, and Integrator.The Producer
is the individual that has the drive and the discipline necessary to see real results produced. Impatient, active, and always busy, the Producer has little time for idle chit-chat. Direct and to the point, typical Producers are behind-the scenes movers and shakers. Many Producers are attracted to high-intensity departments such as Sales. They are too busy to "waste time" with meetings. They prefer to cut the small talk and get out there to get the job done.The Administrator
ensures that rules are in place and followed, that plans are made and adhered to. Precise and accurate, the Administrator creates methods and procedures to make sure things are done "right". Analytical and logical, Administrators clean up other people's carelessness. They like to keep the organization humming at a steady pace, and are willing to do things more slowly and carefully. Administrators are drawn to tasks that require systemic thinking and precision, such as Accounting.The Entrepreneur
is an ideas person, always asking "why?" or "why not?" A visionary with dreams, plans and schemes, the Entrepreneur leads others to ideas that they would not pursue on their own. Success for an Entrepreneur requires both creativity and risk. They sometimes get bored with short-term tasks, and prefer developing the long-term vision. Entrepreneurs are charismatic, and generate ideas for new projects, new approaches to problems, or even new businesses.The Integrator
is people-oriented. True Integrators value social harmony, and thrive on peacemaking and teamwork. The Integrator's pleasantness is unmistakable. Amiable and empathetic, the Integrator is the first to cooperate in helping with tasks or problems. They prefer to work by consensus, instead of taking a strong position against others. Integrators are attracted to people-oriented occupations like Human Resources.
