Minute taking is important because it is the only way to get an official written account of everything that happened in a meeting. This makes obvious sense for legal professionals who will often need to receive minutes in a written document rather than in a media file such as a video or a sound recording.
Video or audio recordings of meetings are also difficult to sift through if someone is trying to find a specific point of action in the meeting. In fact, it might mean that they will have to watch or listen to the entire meeting just to find the relevant section. In comparison, meeting minutes are properly laid out so that readers can seamlessly find the required information.
It is important that effective minutes are taken when there is a legal aspect to a meeting so that everyone agrees on what was said especially in potentially contentious matters such as disciplinary hearings for employees.
Well-recorded minutes also mean that everyone will know what was agreed upon in a meeting whether or not they were present.
