The type of work varies quite a bit, as the competence is of great use to all kinds of industry that rely on reliability, availability, maintainability and safety. The purpose of Reliability and Maintainability (R&M) engineering (Maintainability includes Built-In-Test (BIT)) is to influence system design in order to increase mission capability and availability and decrease … The maintainability effort produces and uses a significant amount of information and data. The scope of this work is to present a methodology that facilitates the evaluation of a software product’s maintainability according to the ISO/IEC-9126 software engineering quality standard. The maintainability requirements must compete for priority for limited resources with all other requirements. Reverse Engineering is becoming important, since several existing software products, lack proper documentation, are highly unstructured, or their structure has degraded through a series of maintenance efforts. So if the software product provides easy maintainability then we can say software quality is up to mark. In this chapter, we explain what we mean when we speak about maintainability. Software Maintainability is one of the most important quality attributes. It can be defined as the ease with which a software system or component can be modified to be corrected, improved, or adapted to its environment. Software maintainability prediction in the earlier stages of software development involves the construction of models for the accurate estimation of maintenance effort. The maintainability of a software system is determined by properties of its source code. International Conference on Advanced Software Engineering and Its Applications ASEA 2011 : Software Engineering, Business Continuity, and Education pp 272-284 | Cite as Source Code Metrics and Maintainability: A Case Study Design for Maintainability (DfM) is the first step of an effective maintenance program, linking maintenance goals to the design process. This book discusses these properties and presents 10 guidelines to help you write source code that is easy to modify. After that, we discuss why maintainability is important. Author: Andrew Taylor BSc MA FRSA - Art and Engineering in Product Design General Rules - Design for Maintainability: The rules are largely common sense. When we need to update the software to keep it to the current market, without impacting its functionality, it is called software re-engineering. Maintainability metrics include time requires to adapt to a new features/functionality, Mean Time to Change (MTTC), performance in changed environments etc. Software Engineering help chat. Students with a master's degree in Reliability, Availability, Maintainability and Safety (RAMS) are attractive in the job market. 7. We quote the IEEE Standard Glossary of Software Engineering Terminology: maintainability. This study aims at systematically reviewing the prediction models from January 1990 to October 2019 for predicting software maintainability. The software engineering literature proposes many models and metrics to predict the maintainability of a software project statically. Maintainability has previously been described mainlyin two ways, either informally or as a function of directly measurable attributes.

Maintainability Index (MI) [article cited from Wikipedia] Maintainability Index is a software metric which measures how maintainable (easy to support and change) the source code is. The following are illustrative examples. If the testability of the software artifact is high, then finding faults in the system (if it has any) by means of testing is easier. Formally, some systems are testable, and some are not. It only takes a minute to sign up. Maintainability testing use the maintainability requirements of the software it is the effort required to effect the change under the following categories like: Corrective maintenance: In this test, the system is measured to diagnose and fix the problems as soon as it is identified.
