Estimating the risk of in-sourcing is key to the success of the project, but often the risks are hidden in the software being in-sourced. In this thesis I will explore, using measures on the source code, to evaluate the maintainability state of a project, by applying a proposed Maintainability Model. The model defines measures for each maintainability characteristic of ISO 9126, and grades them...

This paper proposes a model of successful maintenance that can represent how maintainability of each software module changes as it ages. We found that some of the metrics, measured from 20 years old system, fit our model; i.e., values of those metrics seem to be proportional to the degree of maintainability. We described each metric’s critical line – a value that can be used for deciding whethe...

This paper presents ongoing work on using data mining clustering to support the evaluation of software systems’ maintainability. As input for our analysis we employ software measurement data extracted from Java source code. We propose a two-steps clustering process which facilitates the assessment of a system’s maintainability at first, and subsequently an in-cluster analysis in order to study ...

Although the belief of utilizing design patterns to create better quality software is fairly widespread, there is relatively little research objectively indicating that their usage is indeed beneficial. In this paper we try to reveal the connection between design patterns and software maintainability. We analyzed more than 300 revisions of JHotDraw, a Java GUI framework whose design relies heav...

This position paper investigates on the need to put software architecture evaluations for maintainability in a broader perspective than is done until now.

introduction: various types of software are used in health care organizations to manage information and care processes. the quality of software has been an important concern for both health authorities and designers of health information technology. thus, assessing the effect of software quality on the performance quality of healthcare institutions is essential. method: the most important healt...

Virtually any soware dependent organization has a vital interest in reducing its spending for sowaremaintenance activities. In addition to financial savings, formany organizations, the timeneeded to complete a soware maintenance task largely determines their ability to adapt their business processes to changing market situations or to implement innovative products and services. With the pres...

Maintainability is perhaps one of the most important aspects of software development in that maintenance costs account for at least 50% of software system lifetime costs. A common maintenance practice is adding new capabilities to satisfy the evolving system dynamics, thus contributing to the ever-growing expenses. This paper discusses some lessons learned from system modifiability that affect ...

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...

The migration of monolithic applications to the cloud is a popular trend, with microservice architecture being commonly targeted architectural pattern. motivation behind this often rooted in challenges associated maintaining legacy and need adapt rapidly changing business requirements. To ensure that microservices sound decision for enhancing maintainability, designers must carefully consider u...
