Lack of communication.
In any industry, at any level, communication is key to being a successful manager. Employees need to know what is expected of them and when specific projects or tasks need to be completed. Communication needs to be clear, and any questions that arise need to be answered.
Once a manager has obvious favorites, he or she loses credibility and the respect of the rest of the team.
Just do it.
The Nike slogan does not work when employees are trying to gain an understanding of the process or project. Rather than expecting your team to simply work blindly on tasks they do not understand, a good manager takes the time to explain what the project is all about and how the team’s work is incorporated into the plan. Remember, the more the team is invested in a project, the better the results will be.
In a rapidly changing business environment, not being open to change can be a major mistake. While you may stick to tried-and-true methods in some areas, you should consider and weigh the value of change in others. Above all, be flexible.
Failing to hear what your employees have to say.
Managers make the mistake of listening but not always hearing what their employees are saying. To manage effectively, you need to understand the needs and concerns of your employees.
Too much technology.
A new breed of managers are more tech-savvy than they are comfortable handling and managing people. Embracing technology is a key to success in the modern office environment, but not at the risk of embracing people skills. Do not hide behind e-mails and other technology.
