Abstract Maintainability is one of the design parameters (reliability, availability, maintainability, and safety (RAMS)) maintenance needed to keep respective in sustainable use. At same time, human involved form interface interaction an engineered product/system designed. Ergonomics a multi-disciplinary science that considers capabilities limitations broader sense. The objective this paper int...

Code smells are manifestations of design flaws that can degrade code maintainability if left to fester. The research in this paper investigates the potential of code smells to reflect system-level indicators of maintainability. We report a study where the strengths and limitations of code smells are evaluated against existing evaluation approaches. We evaluated four medium-sized Java systems us...

Proper decisions play a crucial role in any software architecture design process. An important decision of design stage is the selection of a suitable software architecture style. Lack of investigation on the quantitative impact of architecture styles on software quality attributes is the main problem in using such styles. Consequently, the use of architecture styles in designing is based on th...

In their lifetime software systems usually need to be adapted in order to fit in a changing environment or to cover new required functionality. The effort necessary for implementing changes is related to the maintainability of the software system. Therefore, maintainability is an important quality aspect of software systems. Today Software Architecture plays an important role in achieving softw...

Can software maintainability be assessed at the early design stage? For a preliminary answer, we conducted a case study. The study adopts a set of metrics for class diagram measurement, and defines three indices for maintainability assessment from the defect-correction perspectives. The dataset under investigation includes the defect repository and corrective maintenance history of Apache Tomca...

Maintainability of the software is one of the key quality while evaluating software product. Of the overall software development cost, major stake is employed at the maintenance phase. Maintenance time of software is always greater than its development time, so it becomes essential to measure the maintainability of software so that maintenance operational time can be brought down.While going ov...

Software architecture evaluation has been widely accepted as a powerful means to mitigate risks in the design and evolution of software systems. To date we have conducted more than 75 architecture evaluation projects with industrial customers in the past decade. One recurring lesson learned that we experienced across many architecture evaluation projects is that maintainability indeed is a vers...

The architecture of a software system is crucial since it often affects and limits the quality attributes of the system, e.g., performance and maintainability. In this paper we evaluate three communication components suggested for use in a software architecture using prototype-based evaluation. We evaluate the performance quantitatively, and also present qualitative results on portability and m...

We present the initial design, implementation and preliminary evaluation of a new distributed memory parallel Haskell, HdpH. The language is a shallowly embedded parallel extension of Haskell that supports high-level semiexplicit parallelism, is scalable, and has the potential for fault tolerance. The HdpH implementation is designed for maintainability without compromising performance too sever...
