The Role of a Manager
In the past, many people believed that managers were there just to provide support for frontline staff. However, our understanding of the manager’s function has improved. We know that managers contribute to performance.
But how do they do that, and what exactly do managers manage?
Some experts argue that the day-to-day work of the manager consists of managing three things: organization, communication and people.
Let’s consider organization to begin with. Everybody knows that businesses are constantly changing and evolving. One of the purposes of the manager, those experts believe, is to manage this change for the benefit of both the business and its people.
Secondly, managing communication is necessary to make everyone in the business share a common purpose and know their own role in achieving that purpose.
Finally, individuals need to be managed to ensure that they are motivated to do their work well, and that this work also gives them personal satisfaction and fulfillment. If you ask employees what qualities they value most in a manager, the majority will tell you that they need a manager who can listen to them attentively and sympathetically. Obviously, nobody likes talking to a brick wall, and the ability to communicate clearly with colleagues is essential to anybody in a management position. Secondly, when staff worry over certain issues, a good manager should respond to their concerns promptly and also deal with any problems as soon as they arise. Trust is also rated very highly, so managers should also believe in their employees' abilities and be prepared to delegate responsibilities to them whenever possible. Finally, a good manager should also invest in regular professional development opportunities for their staff.
In conclusion, we can see how the three elements of organization, communication and motivation in turn determine the success and profitability of the business. The third element is particularly important. Indeed, there seems to be a strong link between how well managers carry out their motivational tasks and how well employees perform. If the managers fail, the company fails; if the managers do well, then the company prospers.
