Isolated and individualistic are key words. If you believed in them, you would build cube farms for people to work in. For example.
Is there another hypothesis? Turns our there might be several, but one is that humans are fundamentally like all 'pack' mammals. We work and have worked, over thousands of years, in small teams, and these teams support the members inside the team. We have a limbic brain or limbic system that supports the huge emotional and 'social processing' needs of pack living.
Here is an article on the limbic system.
(As you will start to see, the spiritual, physical and thought-memory processing aspects of the brain are quite complex, largely sub-conscious, and quite fascinating. And there is much for us still to learn, IMO.)
How does Scrum inter-operate with this?
Well, first Scrum seems implicitly to recognize the pack or mammalian nature of people, and organizes individuals into teams. (Our mammalian natures may be one of the reasons for this, but certainly not the only reason.)
Scrum implicitly seems to understand that the team starts to be a source of well-being and of motivation for the individual. While the team demands something of the individual, it also supports him (eg. "can I help you with that?"). The team provides this 'pack' sense of belonging. That they say we all need. (And I think I believe 'them' on this.)
More than a sense of belonging, it gives us a sense of purpose. We want the team (pack) to succeed. And we want to contribute to the team's success. To the degree that each person identifies with the team, this is a whole set of subconscious associations that each of us tends to make with the team.
Did the designers of Scrum do all of this on purpose? Well, I have worked with Jeff Sutherland a lot, and I have never heard him put things this way. But he has suggested that there is more going on than can be explained.
And now to you....
Assuming that we as humans are largely pre-rational mammals with a need for a 'pack', in what specific ways would you use this information to make your Scrum team more successful?
