The ISO 9126 Quality Characteristics
The ISO 9126 document is the product of an international effort.
ISO: International Organization for Standardization
The document defines six broad quality characteristics as shown in Table 17.4.
The document includes an example quality model (Figure 17.2) that further decomposes the quality characteristics.
Figure 17.2 is just an example, and not a universal one.
The 20 subcharacteristics of Figure 17.2 have been defined in Table 17.5.
