Explanation:
Professor Henry Mintzberg is a prolific and an amiable author on business and management. He was born on the 2nd of September, 1939 and works at the Desautels Faculty of Management in McGill University, Canada.
According to Prof. Mintzberg in his book titled "Mintzberg on Management: Inside our Strange World of Organizations," there are ten (10) primary roles which can be used to classify the functions of a manager; figurehead, liaison, leader, monitor, negotiator, entrepreneur, disturbance handler, spokesperson, resource allocator and disseminator.
Additionally, Mintzberg determined that managers tend to rely more heavily on verbal communication than written communication when conducting business. This is simply because managers consider a written communication such as memo, reports, or letters consume more time when compared with verbal communication such as telephone calls, meetings or face-to-face conversations .
