Brent Simpson gave a presentation at the MEAS Symposium 2015 on leading issues in extension and rural advisory services. He discussed Rogers' model of the adoption process and innovation characteristics that influence adoption rates. The adoption process involves awareness, interest, evaluation, trial, and adoption. Innovation characteristics like relative advantage, complexity, risk, trialability, and observability impact adoption. Simpson noted it takes time to reach scale and that the nature of scale means not all farmers will adopt an innovation. He recommended starting with good innovations, careful targeting, purposeful outreach, matching methods and messages to adoption phases, ensuring innovations are actionable, allowing trial and adaptation, understanding it takes time to reach scale, and using monitoring to assess progress
