I have found that trying to find a role (job) for those with limited capacity is also critical.
There is also a community assessment process that could help identify the greatest challenges. This assessment process is not in the book but on this book's website https://buildingcommunity12principles.squarespace.com/. I hope I answered your questions.
PS. It was a (fortunate) accident that Strengthening the Foundation is located on the bottom - center in Figure 1.3! Thanks for pointing this out!
