Knowing about your personal strengths gives you additional advantage over those people who do not know about it. When you know what your strengths are and you are working in a team, you always choose to do what you do best. For Example, if I am a good writer, I would choose to do the all the documentation in the team. Also, while working in a team, whether it is an online environment or an offline environment, if you know what are your strengths and what are your team mates' strengths, you can do great while distributing work.
