The 2 pizza rule is a guideline for deciding how many attendees should be invited to a meeting.According to the rule, every meeting should be small enough that attendees could be fed with two large pizzas.

2-Pizza rule

According to the Stanford study<ul><li>Meetings with over 9 attendees are unproductive, as friction grows in proportion to the increase in participant numbers. </li><li>However, in meetings with under 5 people, you run the risk of the participants falling into groupthink. This means people in a group tending to fall in with the majority view, despite actually having a different opinion or even being convinced that the wrong decision is being made.</li></ul>

Importance of Number of participants in meeting

<ul><li>Members of over-sized groups tend to lose respect for the meetings. They prepare less in advance and start to take a more passive -even resigned – role. </li><li>The bigger the group, the lower an individual‘s expectation that her involvement will be noticed. </li></ul>This is the start of a downward spiral into extremely unproductive meetings.

Consequence of over-sized groups

This is also known as the two pizza team concept, and the science behind it has even been confirmed by Stanford University. They discovered in their research that the most productive meetings have 7 ± 2 participants.
