The effect of the quality of program source code on the cost of development and maintenance as well as on final system performance has resulted in a demand for technology that can measure and evaluate the quality with high precision. Many metrics have been proposed for measuring quality, but none have been able to provide a comprehensive evaluation, nor have they been used widely. We propose a practical framework which achieves effective measurement and evaluation of source code quality, solves many of the problems of earlier frameworks, and applies to programs in the C programming language. The framework consists of a comprehensive quality metrics suite, a technique for normalization of measured values, an aggregation tool which allows evaluation in arbitrary module units from the component level up to whole systems, a visualization tool for the evaluation of results, a tool for deriving rating levels, and a set of derived standard rating levels. By applying this framework to a collection of embedded programs experimentally, we verified that the framework can be used effectively to give quantitative evaluations of reliability, maintainability, reusability and portability of source code.
