Some Excerpts:

"40 hour weeks

It may sound crazy, but making sure that your team does not overwork itself is one of the simplest things you can do. As a rule people should not have to work over 8-9 hours per day, even if they want to. There are peaks where I find that people do allow themselves to do this, but you have to make sure it’s not the rule, but the exception. Otherwise you’ll find people starting to “burn” themselves, coming to work late, less productive, and taking long vacations. Eventually, you’ll lose them. "

Pretty good insights as Agile it was should I say
