Use and Identification of Components in Component-Based Software Development Methods

2000

New software systems are needed ever more but to keep up with this trend software developers must learn to create quality software more efficiently. One approach is to (re-)use components as building blocks of the new software. Recently there has been more interest to create component-based software development methods to support this. In this article we first set out requirements for reuse-based software development and then evaluate three component-based methods, namely Catalysis, OMT++, and Unified Process. As a conclusion we argue that evaluated methods produce prefabricated components and that component-based means that software developers can change better components to existing syste…

Which Test Artifacts Testing Service Providers should Reuse and How? Experiences from a Case Study in the Chinese ICT Sourcing Market

2011

Software testing service providers are facing new requirements to shorten service times, lower costs, and increase service customization and quality. Reuse of test artifacts is a possible solution that can help providers to meet the requirements because reuse can improve software quality and productivity. However, the extant literature does not explain in depth which test artifacts should be reused and how. This paper focuses on ICT-enabled sourcing of software testing services in the Chinese market to identify the most important reusable test artifacts. There are two reasons for this research. First, most Chinese service providers are small or medium-sized and have to overcome obstacles su…

Industrial Application and Evaluation of a Software Evolution Decision Model

A modest but practical software process modeling technique for software process improvement

2002

One of the main problems with software engineering is due to the difficulties in evaluating and improving our software processes, especially in the light of the fact that reuse depends on a process which supports it. Generally used approaches to the evaluation and improvement of software processes are based on the CMM, for example. In this paper we present a technique to improve software processes through modeling and evaluation. The presented technique is fairly easy to use, provides reasonably good results and requires only a fraction of resources required by CMM appraisals. Copyright © 2002 John Wiley & Sons, Ltd.

Use of Non-IT Testers in Software Development

2007

Because of a shortage of IT specialists, many companies which are not involved in software development business are forced to use employees who have minimal or no any knowledge about software development and IT as testers (let's call them non-IT testers). The author of this paper has used years of experience in working with such testers to provide a description of them, looking also at their most typical testing styles and the problems which occur for testers, their colleagues and bosses, and the overall software development processes. Non-IT testers often feel like second-class employees, because they are forced to work in an environment in which they do not have sufficient skills. This pa…

A metrics suite for evaluating agent-oriented architectures

2010

The Multi-agent Systems (MASs) paradigm continues to consolidate itself as a new branch of software engineering. Traditional software engineering strongly recommends to apply metrics in software developments. However, several research groups of experts in agent-oriented software engineering agree that classical software metrics and object-oriented metrics cannot directly measure the quality of MAS architectures. For this reason, this work proposes a suite of metrics to measure certain quality attributes of MAS architectures, considering agents and their organization. Most of these metrics are inspired by object-oriented metrics but they are adapted to agent-oriented concepts. Proposed metri…

Human Simulation: A Transdisciplinary Approach to Studying Societal Problems

2019

In this chapter, we present a transdisciplinary framework where humanities scholars, social scientists, and engineers can work together to tackle large and complex societal problems. We identify the steps required to construct a human simulation model and the concerns and issues that must be addressed to ensure success. We also present some basic definitions and assumptions inherent to developing this sort of model.

Smart Technologies for Improved Software Maintenance

2015

Steadily increasing complexity of software systems makes them difficult to configure and use without special IT knowledge. One of the solutions is to improve software systems making them “smarter”, i.e. to supplement software systems with features of self-management, at least partially. This paper describes several software components known as smart technologies, which facilitate software use and maintenance. As to date smart technologies incorporate version updating, execution environment testing, self-testing, runtime verification and business process execution. The proposed approach has been successfully applied in several software projects.

A Case Study of Open Source Software Development in Proteomic Area: The LIMS ePims

2008

The objective of this paper is to provide an illustrative feedback on development of Open Source software among several partners. We describe the first stage of the design of a specific software package, namely a customized Laboratory Information Management System (LIMS) for biology applications. This software package is structured in several modules which are reusable and can be customized for other applications. In this paper, we address the problem of multi-licensing for the same software tools due to the participation of several partners, the reuse of code source, and the subsequent distribution of this produced software.

The Comparison of Software Reliability Assessment Models

2015

Abstract The reliability of the software represents one of the most important attributes of software quality, and the estimation of the reliability of the software is a problem hard to solve with accuracy. Nevertheless, in order to manage the quality of the software and of the standard practices in an organization, it is important to achieve an estimation of the reliability as accurate as possible. In the present work there are described the principles and techniques which underlie the estimation of the reliability of the software, starting from the definition of the concepts which express the attributes of software quality. It is taken into account the issue of the estimation of a software…
