The paper introduces a new object-oriented metric to evaluate maintainability of the software system at the design stage. Unlike well known object-oriented metrics applicable only to one class or to a category of several interconnected classes the proposed one evaluates the degree of extensibility for the whole static design. The metric is based on the main principles of objectoriented design a...

Software re-engineering consists of a set of activities intended to restructure a legacy system to a new target system that conforms with hard and soft quality constraints (or non-functional requirements, NFR). This paper presents a framework that allows specific NFR such as performance and maintainability to guide the re-engineering process. Such requirements for the migrant system are modeled...

Software maintainability has been an important external quality attribute that concerns both styles of software development, the proprietary model as well as open source. As lots of open source software are predominantly built using the OO paradigm, there exists a need for empirical validation with respect to certain quality aspects especially maintainability. There are a few studies in the pas...

Software organizations face constant pressure due to stakeholder requirements and the increasing complexity of software systems. This complexity, combined with defects in code quality failures, can pose risks To ensure is understood before maintenance, developers must spend over 60% their time modifying improving quality, which costly. study examines impact refactoring activities on maintainabi...

The goal of this study is to present the experiences gathered from the migration of an existing and deployed joint replacement surgery information system from a classical 2-tier architecture to a 4-tier architecture. These include discussion on the motivation for the migration and on the technical benefits of the chosen technical migration path and an evaluation of user experiences. The results...

This study introduces a systems-engineering and evaluation methodology that focuses on the stability of an entire computing infrastructure. More specifically, the conducted research elaborates on the cohesive systems assurance (CSA) methodology, which encapsulates the concepts and methods of product assurance (reliability, availability, and maintainability), performance & scalability, and depen...
