I just realized a subtle characteristic for sprint time box length.  If teams are working to 3 week or longer time boxes that is a good indication of teams working as individuals vs. as a group on a problem that needs to be solved.  There are cases in where maybe there could be lots of testing that would require the longer period yes. However.. I realized this just the other day as I was pondering why I was having troubles completing everything in my two week SWAY sprint lengths.  When i coach people in my mastermind and coaching program we usually work in 3 week sprints vs. two weeks.  I also reflected on teams I coached that were three or 4 week sprints and I realized they were that long because the people worked as individuals. Where in a team efforts which is what scrum is really supposed to be about two weeks or less works well because there is more than one person working the issue. Lets share and please let me know in the comments if you see the same trend.On our Wednesday show about Teams, We and HR on the #5ammesterScrum show 1276.
