Vaibhav, most of these responses have misled you, except for the last.
The Goal of Managing People
The goal of managing people is to create an environment that causes employees to become highly motivated, highly committed, and fully engaged, with very high morale and innovation. They should literally love coming to work and be at least 300% more productive than if poorly engaged. Guru Stephen Covey stated the performance difference as 500%, and my own experience in several turnarounds makes me agree with Covey.
Achieving Employee Engagement
Engagement is the word we use to describe that, but how do we achieve it? Simple and easy!
Management is responsible for supporting work by providing training, tools, parts, materials, information, direction, discipline, planning, and the like to employees. How well management achieves employee engagement is dictated by the quality of this support, with poor support causing disengagement and very high-quality support causing very high levels of engagement. So all management has to do is ensure that support is of the very highest quality.
Listening to Employees
The only way management can achieve high-quality support is to listen to the users of that support—employees. Listen to their complaints, suggestions, and questions just as you do to customers of your products and services to make them more acceptable and pleasing to customers. Listen face-to-face and respond face-to-face to the satisfaction of employees, the customers of your support.
If you don't want to listen to them, insist on giving them orders about doing their work, or don't share every bit of information you have that they want, you will convince them you don't respect them, and they will become disengaged. Would you treat an external customer that way? In short, if you insist on using the traditional top-down command and control approach to managing your people, you will fail miserably at creating a fully engaged workforce.
Meeting Responsibilities
But meet your responsibilities to the very highest standards, and your people will be so thankful for being treated so well, far better than they had ever expected or hoped, that they will eagerly unleash everything they have on their work: all their creativity, innovation, productivity, enthusiasm, knowledge, experience, skills, etc.
I know because that is what I experienced as an executive.
