team size and scrum

Is there recommended size (number of developers) for a team doing agile? Can the size of the team effect the productivity of a scrum?

Thanks,
Aaron

I would say yes. Any number more than 10 is a crowd. Does anyone have patience to listen to more people in a standup meeting. How much one be able to digest ?

Scrum canon states that Team size should be seven plus or minus two. This fits well with my experience. When a team gets too large, it will tend to self-organize into sub-teams.

Good point. How was the number 7 arrived at ?

Should the skill set of the team members be fairly equal or does that matter?

As far as I know, it's based on http://en.wikipedia.org/wiki/The_Magical_Number_Seven,_Plus_or_Minus_Two


The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus

I've heard of teams of 20 to 25 developers working well, and of Daily Scrums with 50 people attending.

That certainly will change the dynamics, though. Typically you will find a technique used called "Scrum of Scrums": http://www.mountaingoatsoftware.com/scrum_team

If you ask Ken Schwaber, he'll start listing different specialties like "Well, you need a couple of programmers, a couple of testers, a UI designer, a database admin, [...] and there's already 7 people for your team."

I am not sure how much others would have patience to listen to if it is a group of 25 people. Certainly not me.Will they find a room big enough for 20+ ? A playground maybe

Scrum of scrums is a good idea.I like it
