The document discusses the House of Quality tool used in Quality Function Deployment. The House of Quality matrix translates customer requirements into engineering targets for new product design. It has six major components: customer requirements, technical requirements, a planning matrix, an interrelationship matrix, a technical correlation matrix, and a technical priorities/benchmarks section. The matrix helps identify what must be done to the product design to fulfill requirements and meet customer needs.

2. HOUSE OF QUALITY

3. Quality function development (QFD) uses a
matrix format to capture a number of issues
that are vital to the planning process.
The house of quality matrix is the most
recognized and widely used form of this
method.
It translates customer requirements, based on
marketing research and benchmarking data,
into an appropriate number of engineering
targets to be met by a new product design.

4. Its general format is made up of six major components.
These include
1. Customer requirements
2. Technical requirements
3. A planning matrix
4. An inter relationship matrix
5. A technical correlation matrix
6. A technical priorities/benchmarks and targets section.

6. The voice of the customer
 The initial steps in forming the house of quality include deter,ining/ clarifying
and specifying the customer’s needs.
1. Clarifying customer needs:-
- customers buy benefits and producers offer features.
- it is most important to translate the wishes of each and every customer into
some tangible values that can be turned into engineering specification.

7. 2. Specifying the customer needs:-
- After determining what items are the most important to the customer,
organization must translate them into particular specifications .
- nothing can be produced, serviced or maintained without detailed
specification and some set of standards.

8.  Each aspects of the desired items must be clearly defined:
- measurements must be defined, heights specified, torques stated and weights
targeted.
- these values can be derived from several locations. Organization can use
known data from market research or conduct new studies to gather necessary
information.
- the needs which were clarified and then explicitly stated, should be satisfied
to the best of that organization’s ability.

9. TECHNICAL REQUIREMENTS
The next step of the QFD process is identifying what the customer
whants and what must be achieved to satsfy these wants.
Regulatory standards and requirements dictated by management must
be identified. Once all requirement are identified it is important to
answer what must be done to the product design to fulfill the necessary
requirements.

10. PLANNING MATRIX
 Purpose:-
To compare how well the team met the customer requirements
compare to it’s competitors.
 Customer rating, typically ranging from 1 to 5 are given to each company
under each requirement.
 The customer ratings are combined with the weighted performance of each
demand to produce over all performance measure for all companies.

11. INTERRELATION MATRIX
 Function:-
To establish a connection between a customer’s product
requirement and the performance measures designed to improve product.
- To obtain the opinions of the consumers as far as what they need and require
from a specific product.

12.  With this customer overview, the company can begin to formulate a strategy to improve
their product.
 In doing this, the strengths and weaknesses of the company are weighted against the
customer priorities to determine
a) What aspects need to be changed to surpass the competition
b) What aspects need to change to equal the competition
c) What aspects will be let unchanged.
 The optional combination is desired.

13. TECHNICAL CORRELATION MATRIX
 Which is more often referred to as the roof, is used to aid in developing
relationship between customer requirements and product requirements and
identifies where these units must work together otherwise they will be in a
design conflict.

14.  The following symbols are used to represent what type of impact each requirement has
on the other hand:-
- strong positive
- positive
- negative
- strong negative
 The objective is to highlight any requirements that might be in conflict with each
other.

15. TECHNICAL PROPERTIES AND
TARGETS
 Technical properties matrix uses specific item to record the priorities assigned
to technical requirements.
 It also provides a technical performance achieved by competitive products and
the degree of difficulty in each requirement.
 The final output of the matrix is a set of the target vakues for each technical
requirements.

16. CONCLUSION
 The house of quality functions as a living document and a source of ready
reference for related products and future upgrades.
 The house of quality helps to identify the critical technical components that
require change.
