Meetings are a necessary evil of organizational life. Most big achievements in business, sports, and life depend upon a collection of smart, talented individuals all pulling together as a team to achieve a common goal. You won't win the Super Bowl without a great team. You won't achieve market dominance without building and leading a great team.
Your business won't survive if your team isn't communicating regularly and executing every play from the same playbook.
In leadership we often talk in terms of, "getting everyone on the same page" before tackling a big problem. We are keenly aware of the importance of ensuring that every team member knows, understands, and is acting to achieve the same mission and goals.
So we "do meetings" to ensure everyone hears the same message at the same time from the same source.
