Maximum and minimum number members in Nexus teams

So Nexus follows the SUGGESTED size of teams found in the Scrum Guide. Keep in mind, there is hard maximum or minimum number for Scrum Teams. 

Firstly, Curtis is right - the numbers in the Scrum Guide are suggestions. Scrum has been seen to work effectively with teams of those sizes. Unlike other aspects of the Scrum Guide, having fewer people or more people than the suggestions does not mean that you aren't doing Scrum anymore.

However, looking at ranges could be useful to understand limitations at which point Nexus may not be adding value. Your calculations for the minimum number of participants is off. You're correct that Nexus is geared toward an organization of at least three teams. You would have a single Product Owner for the Nexus, plus perhaps a Scrum Master for each team. However, the Scrum Guide calls out a Development Team size of between 3 and 9, so 3 Development Team members would be the smallest. This would be 1 (Product Owner) + (3 * 1) Scrum Masters + (3 * 3) Development Team members, or 1 Product Owner + 3 Scrum Masters + 9 Development Team Members. 13 people is probably your minimum size for a Nexus. I'd also point out that there's nothing that says that each team must have its own Scrum Master - in my personal experiences, a skilled and effective Scrum Master can support 2, maybe 3 teams, depending on the maturity of the teams. You may be able to run a Nexus with a few as 11 people if you have a shared Scrum Master as well.

Something else to consider when you have smaller organizations is if it's better to have two larger teams or three smaller teams. Consider the effective points of Scrum (Development Teams of 3-9, plus a Product Owner and Scrum Master). At the lower end ranges of the Nexus, it may be more effective to have one or two Scrum Teams and a much lighter coordination framework than Nexus.

Please help me to understand the maximum and minimum number of persons in Nexus team.

The maximum and minimum number to achieve what?

Dear Thomas Owens,

Thank you for your explanation about the minimum size for Nexus. I understand my calculation mistake ☹.

Now I also think that 11 people should be the smallest size of Nexus.

Is it correct that the maximum number of people in Nexus is 101?

Dear Ian Mitchell,

I am preparing for SPS certification and I was confused about the number of peoples in Nuxus.

Is it correct that the maximum number of people in Nexus is 101?

No. There is no hard maximum number of people in a Nexus.

Based on experiences, most Scrum Teams are most effective with between 3 and 9 Development Team members, a Product Owner, and a Scrum Master. Likewise, Nexus tends to be most effective for approximately between 3 and 9 Scrum Teams. However, you can have a Development Team of 10, 11, 12 or more people or a Nexus of 10, 11, or 12 Scrum Teams. These sizes aren't rules of Scrum or Nexus, but guidance based on what has been seen to be effective. What works for you may be different.

There's a clear difference between a rule of Scrum (or Nexus) and recommendations or guidance. Team size is not a rule, but guidance based on the experiences of most teams in a variety of situations.
