How to manage the parts and the whole is a matter of design. Each part should grow stronger in interaction with the others. I have noted that team members often fall into non-value added work habits and that no one takes responsibility for insisting that these habits not take over the work process. I suggest that the team takes time, before beginning the work, to assess each other's non-value habits. Be willing to give each other feedback Insist that the work get done in the most enlightened way.
Feedback still seems to be a very scary thing for members to provide each other.
And yet, feedback loops are what governs the system and keeps it in homeostasis. Feedback demands collaboration and design between the different parties. KreWs have no idea what the different products are like until they receive the final versions shipped to their homes after the DesignShop event is over. Instead, the environment should be employed so that people who are working on different products can see each other's interim work posted on nearby walls, and so that they are encouraged to kibitz on this work. Also understand that iteration is a property of project management.
