What Is a House of Quality?
The House of Quality (HoQ) is the primary matrix used in Quality Function Deployment (QFD). It translates customer requirements (WHATs) into engineering characteristics (HOWs), quantifying their relationships and prioritizing technical development efforts.
A complete House of Quality typically includes requirement importance ratings, relationship strength matrices, correlation "roof" analysis, and competitive benchmarking.
Why Use Dedicated House of Quality Software?
While many teams attempt to build HoQ matrices in spreadsheets, complexity quickly increases as projects scale. Dedicated House of Quality software ensures consistency, automation, and analytical transparency.
- Automated calculation of characteristic priorities
- Normalized contribution distribution (100% per stage)
- Integrated competitor benchmarking
- Structured correlation roof management
- Conflict detection between characteristics
From Single Matrix to Multi-Stage System
A traditional House of Quality is often limited to one level of analysis. Modern product development requires multi-stage propagation.
QFD Tool enables automatic transformation of characteristics into next-stage requirements, preserving mathematical consistency and traceability.
Engineering Analytics Beyond the Matrix
