“Create a QFD House of Quality for a portable blender with weighted customer needs for cleaning, smooth blending, carrying safety, battery life, and quiet operation; relate them to blade speed, jar opening diameter, battery capacity, and motor noise level, including strong blade-speed support for smooth blending and weaker tradeoffs with battery life and quiet operation.”
Read the decisions behind it.
Customer needs sit on the left so their importance ratings remain visible.
Technical requirements run across the top to create a relationship matrix.
Blade speed has strong support for smooth blending and weaker relationships to battery life and quiet operation, so it has a meaningful importance score.
The roof records supportive and conflicting engineering relationships.
Use QFD early in product planning when customer needs must guide engineering tradeoffs. Use a simple prioritization matrix when technical relationships are not needed.

Common questions
What is a QFD House of Quality?
It is a matrix that translates weighted customer needs into technical requirements and shows their relationships.
How do I make a House of Quality?
List customer needs and technical requirements, score each relationship, then record technical correlations in the roof.
How do I read the roof?
The roof shows whether improving one technical requirement helps or conflicts with another.
Is a template different from an example?
A template provides a reusable matrix structure; an example contains decisions for one completed product.
Do I need an account?
Yes, a free one. No card is asked for.
