Meetings and calls are turning into a farewell ceremony? You increasingly ask yourself how many colleagues should actually participate in them? The two-pizza rule states that a meeting or call can easily be limited to the number of people that can be fed with just two large pizzas. This rule helps: - prevent groupthink, which occurs when the need for the group's overall consensus outweighs the judgment of individual members (hello, cognitive biases); - avoid the problem of exponentially increasing connections, which increases with team size (ironically, the bigger the team, the more time will be spent talking instead of its members doing the work). P.S. The two-pizza rule is often attributed to Jeff Bezos. It is known that Bezos used two-pizza meetings and small project teams to create a decentralized creative work environment at a time when Amazon was still a startup.
