MCDA of Fonio and Jute value chains in Northern Benin # Decision Support Tool A simple, interactive tool for prioritizing value chain interventions using Multi-Criteria Decision Analysis (MCDA). ## How It Works 1. **Edit** the `data/interventions_matrix.csv` spreadsheet during your workshop 2. **Run** the analysis by opening `Index.Rmd` and clicking "Knit" 3. **View** the results with ranked interventions and visual heatmaps ## Editing the Data ### Setting Priorities (Row 2) - Keep `type = "weight"` - Set importance weights (0-100) for each objective - Total should ideally equal 100 ### Adding Interventions (Subsequent rows) - Use `type = "intervention"` - Add new interventions as needed - Score expected impact (0-100) for each objective ### Adding/Removing Objectives - Add new columns for additional objectives - Remove columns for objectives you don't need - The tool automatically adapts ## Output The report provides: - **Ranked list** of interventions by total score - **Heatmap** showing complete decision matrix - **Bubble chart** visualizing feasibility and impact (weighted scores of variables in each category) - **Key insights** and recommendations ## Requirements - R and RStudio - tidyverse package: `install.packages("tidyverse")` ## Tips - Use 0-100 scale for consistent scoring (requires a discussion about what '0' and what '100' mean for each variable) - Involve stakeholders in both weighting and scoring - Re-knit frequently as data changes during workshops
