What is the 2 pizza rule? ›

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.

Evaluate team sizes: Assess your current teams and determine if they exceed the ideal size for the Two-Pizza Rule (around 5 to 7 members).

The Ideal Team Size

Jeff Bezos' infamous two-pizza rule limits teams to 5–7 people, which can also be backed by research on ideal team sizes. According to organizational behavior expert J. Richard Hackman, “The rule of thumb is no double digits.

"We try to create teams that are no larger than can be fed by two pizzas," said Bezos. "We call that the two-pizza team rule." The smaller the team, the better the collaboration. Collaboration is very important, as software releases are moving faster than ever.

Number of Guests multiplied by 3 ( avg. slices a person eats) then divide that by 8 (avg slices on a large pizza) = how many pizzas you should order.

Regular size with its 4 slices serves a single person, medium size with 6 slices serves two buddies or a couple. And our large pizza with 8 big slices serves a family of four. Look around the circle of your friends, contemplate their appetite and decide the size accordingly.

If 5 people are sharing 2 pizzas, each pizza will be cut into 1/5 size pieces giving 1/5 from each pizza to each person. Since there are 2 pizzas, 2 x 1/5 = 2/5. So 2 ÷ 5 = 2/5.)

While it can be tricky to estimate how many slices people will eat, you don't want to underestimate anyone's appetite, either. Three slices per adult and two slices per child offer a good base to start from when you're estimating how many pizzas to order.

The "Two Pizza Team" rule states that a team can only be big enough to be fed with 2 pizzas. Incidentally, the rule comes from Amazon founder Jeff Bezos himself. Even though decades have passed since the origin of this pizza rule, Amazon is still keeping the "two-pizza team rule" alive.

Now, this doesn't mean that Jeff Bezos is constantly buying pizzas for his teams, but what it does mean is that he is focused on keeping teams small so they can collaborate and move quickly without costing the company unnecessary money.

What is the two pizza guideline? ›

The “two-pizza rule” advocates for smaller team sizes to promote more effective communication and cooperation. Limiting the team size to what can be fed with two pizzas ensures that everyone has a voice and can actively participate in discussions.

The theorem is so called because it mimics a traditional pizza slicing technique. It shows that if two people share a pizza sliced into 8 pieces (or any multiple of 4 greater than 8), and take alternating slices, then they will each get an equal amount of pizza, irrespective of the central cutting point.

In order to be a true pizza-lover, you have to know some fun-facts about pizza! 93% of Americans that eat pizza, do at least once a month. According to a recent survey by Mintel, it is estimated that 93% of Americans who eat pizza eat it once a month. The most expensive pizza in the world costs a whopping $12,000.

Here's the reasoning behind that rule: Most medium pizzas are cut into eight slices unless otherwise requested. Therefore, each slice comprises 1/8 of the pizza. Since the average hungry person eats three slices of pizza, it follows that you must simply multiply the number of guests by 3/8.

If a circular pizza is divided into 8, 12, 16, ... slices by making cuts at equal angles from an arbitrary point, then the sums of the areas of alternate slices are equal.
