House of Quality

Quality Function Deployment (QFD) uses a matrix format to identify issues that are essential to the design planning process.

The House of Quality Matrix is the most used form of this QFD.

It translates customer requirements into engineering targets to be met by a new product design.

Conclusion

Performance testing provides important information about the product under test

Functional analysis may vary between different schools of thought, but they all should provide similar information as they show the functional work of the product in a block diagram structure

BOM is an important outcome of RE work

House of Quality is a powerful design tool that correlates the customer requirements with the engineering design targets. This tool can also be used in reverse engineering
