Model-Based Factors to Extract Quality Indications in Software Lines of Code

The lifetime of a product depends on its maintainability. It is proved that a lot of cost spent towards maintainability. Researchers experienced difficulties to measure and improve software understandability and maintainability then software quality. In this work a proposed Model-Based Factors (MBF) is created to help developers to increase software understandability and to improve software quality. MBF estimate s/w standardization level determined by its Liens Of Code (LOC). Seventeen software products were used to validate the research results. A standardization set of source code factors was proposed. The proposed set was created and implemented by the MBF to extract the quality indications through source code segments. The MBF results illustrate positive effect of documented source code to increase the level of software quality. This effect will also improve the software readability and reusability, understandability. Furthermore, it will reduce the maintenance cost of long life software.
