There may be some differences of opinion that there are a different number of functions that management is responsible for. However, the majority of people will agree that there is a core set of functions that every manager must be able to carry out.
Most will agree that planning is the management function that should be at the top of the list. Anything that is important in life needs to start with a plan. This same principle applies to business. A manager must have a plan of action to follow, which revolves around the duties that come with the position.
Having a good plan is important, but if management is not organized, they will not be able to execute the plan, so it is efficient. If management is unorganized, then this will trickle down to the employees. If the employees are not able to get organized, it can spell disaster for the company.
Managers are responsible for overseeing the employees. This may be a small group within the company, or it could be all of the employees. It will depend on the size of the business. The manager may not be responsible for the hiring, but they will be responsible for the employees once they start with the company.
It up to management to provide direction for the employees. They do this through communication and employee interaction.
The manager must maintain control over the activities of the employees. If this is not done, then the organization suffers, and employees do not have any guidelines to follow.
Some things that define the function of management will include co-ordinating and motivation. These can be included in the main functions as listed above.
