I have been to few meetings, where minutes are taken, this are really important especially if you are forgetful or busy in general, because you can always look back at it to know what happened in the meeting. The main reason for this is, because lots of tasks are assigned during the meetings. People have finish this task by given deadline. This are important because sometimes people forget, who was assigned what and by whom. With the minutes, no one can go back on their word, because its recorded. They also act as guideline for people who either missed the meeting or arrived late to the meeting, so that they know what happened in the meeting.
