Evolution of the Course¶
Case study rotation: Ethiopia and Colombia were the primary cases from 2017-2020. Vietnam was always present as a benchmarking comparison. Rwanda was introduced as a primary case in 2024, replacing Ethiopia. Vietnam shifted from benchmark to primary case in 2025.
Format changes: The course ran as a two-day format (Day 1 + Day 2) from 2017-2023, condensed to a single session in 2022, then moved to a single combined deck starting in 2024.
Guest speakers and panels: Live panels with field practitioners were introduced in 2021 (Indonesia, Cote d'Ivoire) and repeated in 2023. Joel Arusha and Dave Betts co-taught in 2024.
Sustainability content: Climate, CO2 emissions, gender equity, and certification standards were added as a dedicated section starting in 2023.
Core framework: The Map / Breakdown / Benchmark methodology has been stable since 2017. The waterfall chart, export price curve, and yield comparison chart have been recurring visuals throughout.
