2-D Software Quality Model and Case Study in Software Flexibility Research

This work starts from the analysis of the traditional decomposed quality model and the relation quality model and discovers the deficiency of them presented the software quality. Then based on the measurement theory a 2-D software quality model is proposed, which synthesizes the traditional decomposed quality model and the relation quality model to comprehensive present software quality. In particular, the use of Bayesian network theory to construct the uncertainty casual relationships in the same level notions establishes a theoretical basis for the software quality assessment and prediction. Finally, the method of 2-D software quality model constructing and the initial result are presented by the research on the software flexibility in the study of cases.
