Schulman (1995): Measuring Object-Oriented Design, Journal of Object-Oriented Programming, 8 (4), Jul/Aug 1995, pp. Quality models have been proposed to solve this problem. Their quality model does not address maintainability as they focus on attributes of service design artifacts, but a number of the proposed design properties and metrics will be adopted here. Oman, P.W. Google Scholar; 122. He uses his background in offensive security testing to help improve software and IT security based on industry best practices. To estimate the maintenance cost and maintainability of software, many software metrics and models have been proposed in the literature. It was proposed by Oman and Hagemeister in the early nineties. This paper provides a review of this literature and the related state-of-the-art. Object-oriented design has been shown to be a useful technique to develop and deliver quality software. Definition 1: -Maintainability is most commonly referred to as “the ease in which a system (for instance, a website or web application) can be modified or extended” (via Jeremy D. Miller). Currently, there is no comprehensive basis for assessing and improving the maintainability of software systems. Quandary Peak Research. Measuring software maintainability is non-trivial as there is no single metric to state if one application is more maintainable than the other and there is no single tool that can analyze your code repository and provide you with an accurate answer either. Software complexity metrics, for example, rarely measure the "inherent complexity" embedded in software systems, but they do a very good job of comparing the relative complexity of one portion of a system with another. It also proposes a maintainability model that is based on the analysis of the relationship between object-oriented metrics and maintainability. So, how did you define maintainability? Assessing the maintainability of a software system is equivalent to making a prediction, on the basis of information about the existing system, about the effort Daly, J. W., J. Miller, J. Brooks, M. Roper and M. Wood (1995): Issues on the object-oriented paradigm: A questionnaire survey, DeMarco, T. 1982, Controlling Software Projects Prentice Hall. Software development metrics are quantitative measurements of a software product or project, which can help management understand software performance, quality, or the productivity and efficiency of software … ICSM 1992. ] Maintainability refers to the ease with which you can repair, improve and understand software code.

In this paper we first introduce the theoretical concept of object oriented metrics, specifically of CK metrics suite.

The MI is a composite number, based on several unrelated metrics for a software system. Software complexity metrics, for example, rarely measure the "inherent complexity" embedded in software systems, but they do a very good job of comparing the relative complexity of one portion of a system with another. It is thus vital to know which dimension of maintainability is more important for your maintenance team when measuring the quality of your application and carry out the reviews and refactoring with those in mind.

Complementarily, the software maintainability is considered a software attribute playing an important role in quality level. These may or may not be the exact same ones that you thought of, but there will be a great deal of overlap. These core facets can be broken down further, to gain further insight into the maintainability of the application: Those are the four major dimensions on which one can measure maintainability. There is no single metric that can accurately capture the notion of maintainability of an application. 285--289. 21st IEEE International Conference on Software Maintenance, 26-29 Sept. 2005, pp. Poels G. and G.

This information may exist externally as a traceability document, but even having some information in the source code – either by the way it’s laid out into packages/modules, naming conventions  or having READMEs in every package explaining the role of the classes, can be immensely valuable.

That is, is there a mapping from code to requirements and vice versa that could be discerned from the code base itself? ICSM 1992. ] Traditionally, this activity is performed by extracting source code metrics using data mining techniques. Hence, it is focused more on methods than on classes, as is the case for the CK- metrics. Various software metrics and models have been developed and described. Paul W. Oman, Jack R.
