K - Key Message - What Must Farmers Know
Share the most important information for successful testing.
M – Message form and delivery: How Should I Reach Farmers?

The ASK ME method
A simple framework to turn knowledge into action
A — Audience and Needs. Who are you reaching, and what actually constrains them?
S — Solutions. What will work here, and can farmers realistically try it?
K — Key Message. What are the few things they must get right?
M — Message Form and Delivery. How can you best reach them, and who do they trust?
E — Evaluation. What changed, and what would you do differently?
Developed by Mark A. Bell (and colleagues) — UC Davis - previously UC Agriculture and Natural Resources Vice Provost; international program leader at UC Davis, Director, IRRI, and Head, CIMMYT.
