Local Methods

Honor the routines, rituals, and rhythms that already work. Then improve at the margin.

OBSERVEBORROWADAPTSHIPITERATELOCAL LOGIC, LOOPED

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.

Four Tests
Observe
Map the existing workflow before proposing a new one.
Borrow
Reuse rituals, schedules, and language the community trusts.
Adapt
Modify your product to match the method, not vice versa.
Iterate
Improve at the margin, in tight loops, with the community.
Canonical Cases

Casas Bahia

Layered formal credit on top of informal Brazilian trust networks.

SKS Microfinance

Distributed micro-loans through existing women's self-help groups.

Voxiva

Used community health workers' existing rounds for disease surveillance.

Field Prompts
  • What ritual or routine does this community already trust?
  • Can our solution slot into an existing schedule instead of creating a new one?
  • What is the smallest improvement that compounds weekly?
