A framework for analysing the system quality

Business oriented Software Industry requires to develop products over a short span of time, for this a good Enterprise Architecture is required to promote and to find a solution for the increasingly complex socio - technical system that are hard to change and yet they face enormous pressures to increase operational efficiencies and to adopt to novel challenges. Since creating an Enterprise Architecture model is expensive and keeping the quality in mind, this paper suggest a theory based model for analysis of system quality. The ISO 9126 based theory is at the back of the analysis of the system quality, which has been introduced in the form of extended influence architecture. In conclusion, an example exemplifies that the theory based model sustains the analysis of the system quality.
