Winrock’s Lean Toolkit for Market Systems Development maximizes value and profits for market actors and prioritizes efficient use of existing resources first. This toolkit is designed to support project teams and staff in planning and strategy, specifically to identify and understand opportunities and systemic points for program prioritization and intervention using a value stream mapping methodology. These are adapted from mainstream lean tools, with a specific focus for agricultural programs, to identify wastes and solutions for market development and growth through efficiency and value, which will result in increased competitiveness and profits.
