As known that the management is the activities performed to manage and run a business, department, and people. It is the act of being the leader and the responsible for a certain achievement or performance.
Also it could be referred to a group or people involved in the four general functions of management: Planning, organizing, leading and coordinating of resources. (Note that the four functions recur throughout the organization and are highly integrated).
However the person who is in charge for a group of people or a department is the manager who is responsible to perform those functions.
The manager is a person tasked with overseeing one or more employees or departments to ensure these employees or departments carry out assigned duties as required. Depending on the size of the company there might be a single, dual or triple management layer involved.
In large companies management is basically divided into three tiers: upper or senior management, mid-management and lower management. Lower management includes managers who operate at basic levels of commerce or function. Mid-level management oversees lower-management and generates reports for senior management. Senior or upper management commonly consists of a board of directors or shareholders who own the company and are responsible for making key decisions that affect the company.

In this article I will elaborate more about those four main managerial functions and their characteristics in order to see what they involve, and what kind of skills might require.

a. Planning: Simply put, planning is selecting priorities and results (goals, objectives, etc.) and how those results will be achieved. Planning typically includes identifying goals, objectives, methods, resources needed to carry out methods, responsibilities and dates for completion of tasks. Examples of planning are strategic planning, business planning, project planning, staffing planning, advertising and promotions planning, etc.
It is about gaining the most benefit while making the wisest use of available resources. To that end, one goal of this type of planning is to establish realistic data in terms of how much is needed of each resource required and how long the resource will be required.
For example business planning is a process that involves the creation of a mission or goal for a company, as well as defining the strategies that will be used to meet those goals or mission. The process of business planning can be very broad, encompassing each aspect of the operation, or be focused on particular functions within the overall corporate structure. Often, business planning involves the utilization of resources within the company as well as engaging the services of consultants to assist in designing and implementing the plan.

b. Organizing: it is allocating and configuring resources to accomplish the preferred goals and objectives establishing during the planning processes.
It is how to handle many duties and responsibilities in order to avoid time and effort wasting so mission could be done accordingly, and sources will be used properly.
Also organizing could be the act of managing the resources in logical manners; what we need and what we don’t; what we will use first and what is later; what we will finish first and what we will postpone…
Organizing simply could be like having the right item in the right place!

c. Leading: is establishing direction and influencing people to follow that direction.
Leading is the act to make people follow, accept and perform what a leader (manager) has planned and what he is asking.
A strong leader who is able to show a strong personality, be part of the team, keeping the team under control, and most of all he/she should remember that the group will look to him/her for answers. You want to be a leader so make sure you are prepared enough to answer them when they come up.

d. Coordinating/Controlling Resources and Processes: coordinating is monitoring and adjusting resources and processes to achieve goals and objectives in a highly effective and efficient fashion.
In other ways it is the activity to achieve goal with less cost and best efficiency or result.
It is the process to make sure the resources, materials, and efforts are in place and they meet the standards.
For example, quality control involves the examination of a product, service, or process for certain minimum levels of quality. The goal of a quality control team is to identify products or services that do not meet a company’s specified standards of quality. If a problem is identified, the job of a quality control team or professional may involve stopping production temporarily. Depending on the particular service or product, as well as the type of problem identified, production or implementation may not cease entirely.

Based on the above we can conclude that to perform the management responsibilities, and to be a manager, qualifications and professionalism are always required.
Also manager should be ready for “bad situations” and “good solutions”, he/she is in charge leading and advising the team or department. He or she is not a just person sitting there in the office to sign papers. Management is the core of operations and process, and by performing the functions appropriately the manager shows the professionalism and impresses the others, and proves that he/she deserves to be there. And as it says “it is better to leave it if you cannot handle it”!
