The fundamental structure of a software system is referred to as the software architecture. Researchers have identified that the quality attributes of a software system, e.g., performance and maintainability, often are restricted by the architecture. Therefore, it is important to evaluate the quality properties of a system already during architectural design. In this paper we propose an approac...

Most of the software cost is due to maintenance. In the last years, there has been a great deal of interest in developing cost estimation and effort prediction instruments for software maintenance. This work proposes that module connectivity is a key factor to predict maintenance cost and uses this thesis as the basis to develop a Connectivity Evaluation Model in OO Systems (MACSOO), which is a...

Maintenance of a computer-based system accounts for a large proportion of the total system cost. However, no well-established techniques exist for assessing the maintainability of such a system. This paper presents a case study in assessing the maintainability of a large, software intensive system. The techniques we used are described, and their strengths and weaknesses discussed.

The paper discusses the innovative patterns such as subtraction, multiplication, division, task unification and attribute dependency change for evaluating the software architecture to identify the risk factor, check all the quality attributes have been addressed in the software. Architecture evaluation for a large system can be done by using an approach called Architecture Tradeoff Analysis Met...

Software quality characteristics, such as reliability, maintainability, usability, portability, among others, are directly determined by software architecture and, in consequence, it constitutes a very important artifact to be evaluated as soon as a general design is obtained. This article proposes a method to estimate software reliability by evaluating software architecture. Our method combine...

We introduce general methodologies for benchmarking the availability and maintainability of computer systems. Our methodologies are based on fault injection, used to purposefully compromise availability and to bring systems to a state where maintenance is required. Our availability benchmarks leverage existing performance benchmarks for workload generation and data collection, measure availabil...

Abstract Technical Debt Management (TDM) includes activities such as identifying, measuring, and prioritizing technical debt. It is mainly performed to proactively mitigate the risk of losing maintainability evolvability software product which results in reducing team velocity. Despite importance TDM, its adoption companies remain limited. Software are witnessing high market demand competition ...

Abstract The post-construction phase represents a critical milestone in the project lifecycle. This is because design errors and omissions as well construction defects are examined during this phase. traditional procurement approaches that commonly adopted projects separate from construction, which inhibits contractors, suppliers other parties providing team with constructive comments feedback ...
