There are multiple occasions where you have the opportunity to build multiple types of communities.
You might be launching a pilot program and trying to decide what topic to launch first.
You might be considering expansion to new languages and feel unsure which language to pick first.
You might be considering launching a new group and deciding which group to target first.
There are two major considerations here. The first is whether you have strong support for this already (i.e. are you fully resourced for a new community/group?) or do you have to prove results to get the resources (90% of the time it’s the latter).
If you have the support you want, target the biggest win. If you don’t, target the quickest win.
For the quickest win, refer back to this model here.
Find the group which has the combest combination of:
a) The biggest-sized audience.
b) The audience with plenty of existing questions/problems to solve.
c) Has limited competition for members to solve those problems today.
