In Scrum the Team Size is 7 +/- 2. Not 50

I was talking to someone yesterday telling me about her previous employer and the scrum team they had.  I almost fell over when she said they had 50 people on their team at the time.  Surely that was 6 or 7 smaller teams right? No – just one team.

In fact there were so many people at the daily stand up that they used to pass around a microphone so everyone could hear!  However, things weren’t quite as bad as I might think because of pair programming.  Only one person in two actually had to talk because the second person in each pair would’ve just said the same as the first.  What about rotating pairs during the day? And even then, 25 people in a team is too large.  At that size it’s not a team anymore – it’s just a crowd.

Remember, it’s 7 plus or minus 2 for the ideal scrum team size.  Not 50!

  2. it begs to ask the question though - did it work for them, and if so how?

    Also given that they'd obviously had the problem for long enough to consider and organise a mic for stand-ups, this was a problem they could see coming - did they eventually see a reason to have smaller teams?

  3. @rex I didn't have much time to ask that many questions, but I doubt it very much.
