As a manager, knowing your team’s strengths will help you assign tasks and understand where each employee would create the most value for the business. However, it’s all about balance, so do not pigeonhole your team by only giving them tasks within their assigned strengths. They need to learn how to strengthen their weaknesses, too.
As an individual, it’s obviously helpful to understand your strengths and weaknesses. You want to better understand where you will find satisfaction and success in life due to your strengths. However, understanding the areas outside of these strengths will help you step outside of your comfort zone and become a more well-rounded worker and person.
