This document introduces Lean Design as an approach to optimize value and minimize waste in the design process. It discusses that design drives 80% of product success but is often not considered early enough in the development process. Lean Design aims to involve stakeholders from the start and take the entire product lifecycle into account. Key benefits include improved opportunities, reduced waste, and differentiation from competitors. The document outlines eight dimensions of Lean Design Excellence: stakeholder collaboration, optimization of value, prevention of waste, real-time measurement, product and process accountability, systematic innovation, team leadership, and senior management support.
