Structured Meetings Are The Product Manager’s Secret Weapon
Meetings are a necessary evil for many. There is still no better way than a meeting to get a group of people together and make a decision in a short period of time. Yet, many of us dislike meetings. This is in part because many meetings are unstructured, leading to discussions that go off-track and people seeing them as time-wasters. Another reason is because meetings tend to be one-directional. One person talks to the entire group who are just listening passively.
