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...

University Institute of Engineering and Technology, Panjab University, Sector 25, Chandigarh INDIA _______________________________________________________________________________________ Abstract: Software maintenance is a valuable part of software development. Maintainability is one of the main aspects of software quality in software products. Object Oriented Programming has played a crucial r...

This paper presents a method to compute metrics that predict maintainability of a system with respect to its event processing. The metrics reflect the complexity of event dependencies in an object-oriented system. They can be computed from a UML design or from a program code. The maintainability factor is obtained by comparing the calculated metrics with the metrics for a design conforming to a...

This paper gives a practical systematic approach towards the maintenance procedure optimisation of critical industrial unit in operation, to improve its maintainability. The resolution maintainability challenge (Vibrating screen - VSU) was realised by performing two-phase analysis, encompassing criticality and assessment. assessment comprised failure investigation using fault tree analysis (FTA...

In order to continue to make progress in software measurement as it pertains to reliability and maintainability, we must shift the emphasis from design and code metrics to metrics that characterize the risk of making requirements changes. By doing so we can improve the quality of delivered software, because defects related to problems in requirements specifications will be identified early in t...
