  Nowadays, quality definition, assessment, control and prediction cannot
easily be missed in systems engineering. One common factor among these
activities is quality quantification. Therefore, throughout this paper, the
authors focus on the problems relating to quality quantification in systems
engineering. They first identify the main drawbacks of the current approaches
adopted in this domain. They demonstrate how current solutions are not easily
repeatable and adaptable across systems and how in most cases, the related
standards such as ISO/IEC 25010 or Automotive-SPICE to cite just a few, are not
used as they are within companies today. Fortunately, qualimetry, a young
science with the purpose of quality quantification, provides the tools to
resolve these gaps. To be able to use these tools, the authors propose a
synthetic representation of qualimetry and its six pillars, named the ''House
of Qualimetry'' and explain the fundamendal aspects of qualimetry. They
identify a set of 8 attributes to characterize the design quality model and
based on these attributes, propose a new process to design or adapt the quality
model. Among these attributes, a new one is introduced to capture and measure
the quality model evolution and adaptation aspect: the polymorphism and the
polymorphism degree. Finally, the authors consolidate the measurement part
thanks to a new measurement process before returning to the benefits of these
contributions to systems engineering.
