1. Introduction
Developing an application passes through many steps such as analysis , designing , programming and production .After we have an application, we start looking for the quality of this application , this stage not less important than the previous .We should acknowledge that the quality of the application is one the most important factors to success the application . According to the IEEE Standard Glossary of Software …show more content…

Metrics are assigned to each sub factor for the real evaluation Research Problem even the development had made in software quality area ,but still there are some issues that prevent them to become widely accepted in practice. In one hand it is disappointed by the Practitioners, because the quality models was not according to the expected level .It usually not clear how quality models should be set up in practice to assess ,define and predict quality. The major problem is that there are many different models have been proposed from different researcher with different purpose and they not use a uniform terminology.

2. Software quality models

The last 30 years in quality modeling created a many very different models widely termed as “quality models”. The examples for these diverse models is taxonomic models such as ISO 9126 and the metric-based models such as maintainability index and the stochastic models such as reliability growth models.

Quality Model is defined as a model with the goal to describe, evaluate or/and predict quality.
Quality Meta Model is defined as a model contain constructs and rules required to build particular quality models.
Quality Modelling Framework is used to define and evaluate improvement of the quality . This often includes metamodel of the quality and the methodology which describes how the instantiate of metamodel .
