As I always say, form before function and behaviour before tool.
The Connected Leader Attributes model found within the book Flat Army describes fifteen key behaviours that are necessary for leaders (and the organization) to operate as a Flat Army.
Chapters 4, 5 and 6 in the book outline in full detail what the fifteen attributes are all about in addition to outlining the methods in which you can employ in your day-to-day work life. (Click to view a short video on Chapters 4, 5 or 6)
The tree is a metaphor; the roots are your foundation (when you are becoming a Connected Leader) whereas the trunk is when things get done (when you are being a Connected Leader) and you are a fully functioning Connected Leader when there is beautiful foliage beaming from the branches (when you are going beyond a Connected Leader).
