This document is a Quality Function Deployment (QFD) House of Quality document for designing a micro hydro turbine for a sewage treatment plant. It lists 10 functional requirements for the turbine and compares them to 5 explicit and implicit customer requirements. A weight chart shows the importance of each requirement to customers and technicians. Correlations between requirements and competitors are also assessed to ensure the new design meets customer needs better than other options.
