It is hard to measure an employee’s engagement but there is a feel to it. You know when you are engaged in a task, it doesn’t necessarily mean you’re happy -you are focused on it and looking forward to the outcome. There are four main ‘feels’ to engagement which are: the feeling of urgency, being focused, having intensity and enthusiasm. 

These components together create an engaged person especially at work. When you have this winning combination the work that is produced is at its best, its engaged work with a person who took time to put complete focus into it with a level of intensity on achieving their goal and enjoyed the feeling of doing and completing. This recipe has other benefits as well, such as people who get this feeling tend to be persistent in this type of behavior and they take on new challenges with a positive mind. They also are more likely to expand their roles at work and more able to adapt to the changes occurring around them. It can be a win win situation because people want to feel engaged and companies want their employees to be engaged. The result is better work and more efficiency.
