> there is a study or set of studies which shows that, for software projects within a certain broad size range, a team size of 5-7 gets the project done fastest, and that larger teams not only take more man-hours for the same size project but more calendar days I'd like to read those studies. Do you have a cite?

That specific finding was from what appears to be the 1997 QSM study [0], though the description I am familiar with it from (Mike Cohn’s Succeeding in Agile: Software Development Using Scrum, 2010, describes it as covering projects in 2003-2005 (the author, organization, and number of projects in the analysis, and the one result chart from the study that is in the article on the web [1] match between the book and the 1997 one, though, but the chart showing time to complete by team size isn't shown in the article.)
