Efficient Display of Relationships for a House of Quality

       Disclosed is a software scheme which provides a highly
efficient display of Relationships in a house of quality.

      Quality Function Deployment (QFD) is a method to perform
systematic design of a product or a process.  QFD uses a house of
quality as a graphical tool to represent the design.  The figure
illustrates a house of quality.

      A House of Quality represents a design in a matrix form.  Any
design starts with specifications.  In QFD terminology these
specifications are referred to as Customer Requirements (CRs) and are
represented by rows of the matrix.  The design process produces
design parameters referred to as Product Parameters (PPs).  Product
Parameters are represented by columns of the matrix.  A relationship
matrix shows how a CR is related to PPs, and vice versa.  Each row in
the relationship matrix shows how a given Customer Requirement is
affected by various Product Parameters.  Conversely, a column
indicates how a Product Parameter affects various Customer
Requirements.

      The relationship between a CR and a PP is indicated by a symbol
at the intersection of the CR row and PP column.  There are three
strengths of relationships, namely Weak, Moderate and Strong.  Also a
relationship can improve a Customer Requirement or degrade it.  To
fully understand how a CR is affected by PPs, one must examine a
complete row of the relationship matrix.  Most of cu...
