This is an activity you might consider doing as part of your next team meeting. You’ll see one of my own relationship maps for my business here.
Using a whiteboard place a circle on the board first, with the name of your team. First make a list of all the potential people you partner with. Select one color marker for internal team partners and one for external team members. One at a time, map out how close you are to each of these internal and external relationships. IF it is a close relationship place them closer towards your circle, if they are further away place them further away.
Have people indicate what is important about that relationship – is it a relationship which enable you to do things, do you get important information from them, do they provide resources etc? Also note for each relationship what needs attention.
Seeing these interconnections visually can bring to life the relationships, helping people understand how much they are part of a web and dependent on others.
