Local Methods
Honor the routines, rituals, and rhythms that already work. Then improve at the margin.
Every community has a working method, for saving money, raising children, sharing tools, settling disputes, distributing food. These methods are rarely written down, but they are stress-tested by generations. Outside solutions that ignore them fail; solutions that respect them compound.
Local methods include savings circles (susu, chama, tanda), informal credit, community health workers, oral broadcast networks, market days, and faith-based gatherings. They are the operating system the community already runs. The job of the innovator is to write applications for that OS, not to replace it.
Casas Bahia built a credit system on top of informal trust networks. ICICI and SKS Microfinance plugged into existing self-help groups. Voxiva moved health surveillance through community health workers who already made the rounds. The method was local. The improvement was at the margin, and the margin was enough.
