Software quality assurance in Australia: an update

Three recent events are likely to have a significant impact on the future direction of software quality in Australia: the Kean Report, the redevelopment of Australian standard AS3563 and a review of Government purchasing policy as a result of a change of Commonwealth Government. These events, and their subsequent impacts, could have implications and could provide lessons for the software quality assurance industry internationally. These lessons concern: providing adequate education for purchasers, suppliers and auditors on what ISO9000 is all about; implementing appropriate ISO9000-compliant quality management systems, particularly for small and medium sized enterprises; defining an appropriate role for government; and utilizing effective guidance for adopting ISO9001 to software development.     

Efficiency of CAMEtools in software quality assurance

Our paper describes the requirements and possibilities of integration of metrics tools in the field of software quality assurance. Tools for the support of the measurement process are herein classified as Computer Assisted Software Measurement and Evaulation Tools (CAMETools). Software measurement regarded as a special type of metrics application provides a great amount of basic information for the evaluation of the software development process or the software product itself. Our paper examines the effectiveness and destination of software measurement in tool-based software development and is based on an analysis of more than 20 CAME tools in the Software Measurement Laboratory at the University of Magdeburg. CAMEtools are useable for the process, product, and resources evaluation in all phases of the software life cycle (including the problem definition) for different development paradigms. The efficiency of CAME tools is described on the basis of a general measurement framework. This framework includes all steps in the software measurement and evaulation process: metrics definition, selection of the evaluation criteria, tool-based modelling and measurement, value presentation and statistical analysis. The framework includes the main aspects of the process evaluation techniques (Capability Maturity Model, ISO 9000-3 etc.) and product evaluation (ISO 9126, etc.). It is not a disjointed set of aspects: our measurement framework represents an incremental technique for the application of quantification of quality aspects in a required quality assurance     

Software quality standards in practice: the limitations of using ISO-9001 to support software development

Quality management standard BS5740/ISO9001 is a key technology for UK and Europe in the 1990s. This paper shows that the relevance of BS5750/ISO9001 is limited and suggests that standards bodies must develop and endorse new standards to ensure that software quality improvement programmes continue to be adopted by the information technology industry.     

Software quality practices — an empirical study

Concern about the quality of software is widespread. Reliable data about current practice are hard to get as no one likes to admit that they are producing poor software. In a recent survey, Wilson has taken an approach to obtaining data about the practice of software quality assurance among companies in Australia. The same technique has been used here to investigate practice among companies in Europe and America. The survey ams to investigate quality systems used by the organizations, and the application of these systems by software fevelopers. In this paper they are compared with the Australian experience and the results of the survey shown. The company's demographic data and overall response pattern from this survey are compared with Wilson's. Patterns in software quality assurance programs of organizations are suggested by comparing the management's perspective with that of the developers. The most popular software development techniques identified by the developers are prioritized in the order of their popularity by using a weighting scheme and their implications are discussed.     

军用实时系统开发中质量保证模型

提出项目管理和过程技术相结合的质量保证模型,一方面规范项目管理,对承制单位进行国家军用标准资质认证,建立有效的质量管理体系,对软件开发实施全程质量跟踪管理控制;另一方面不断改进和提高开发过程中所应用的技术、方法,采取迭代开发模式,并在开发过程科学有效地开展需求管理、同行评审、软件测试等一系列的质量保证活动.     

Perceptions of software quality: a pilot study

Many software quality initiatives fail because they do not take account of the range of views that people have of quality. New approaches to software quality improvement will not work unless software developers believe in them, no matter how enthusiastic managers may be. This paper reports on a pilot study using the repertory grid technique that found evidence to support these assertions. The study findings justify further work and show that while the repertory grid technique is an appropriate instrument in this area it is resource intensive to apply and may not be practical in a wider study of a representative sample of the IT industry. The paper has practical recommendations for successful introduction of new software quality programmes. These recommendations stress the need for effective communication, leading to a shared understanding of quality, and for realistic goals that recognize the pressure of development schedules.     

软件研制的过程质量管理

从软件质量控制到软件质量保证

本文阐述了在嵌入式系统和在其他执行关键任务的软件中由传统的软件质量控制技术到前涉的质量保证方案的转化：软件在每一个产品和每一个组织中所发挥的作用日益重要。近年来,执行关键任务的应用系统的数量以指数速度增长。这些系统要么失败后损失巨大（空中交换管制系统和其他生命支持产品）。要么纠正费用高（便携式电话和其他用户产品）。为嵌入式系统设计的软件在更多的时候属于“执行关键任务”的范畴,而对嵌入式系统的需求也在继续升温,因此对前涉的质量保证的需求要高于以往任何时候。本文把质量控制到质量保证的转化分为两个阶段：1质量评估（第一阶段）：在开发周期的早期,即在软件到达用户之前,甚至在测试之前识别和排除软件故障,同时提供客观定量的质量评估。2质量保证（第二阶段）：在作更改的时候,通过精确的影响分析,采用强制执行编码标准和防止新错误出现的方法来防止错误进入代码基数。

Quality assurance in micro production

Quality assurance is essential for an efficient support of all developing and manufacturing processes and activities with the forefront objective to reach robust processes with a high throughput of parts meeting their functional requirements. Due to the lack of a broad base of experiences regarding the still developing manufacturing technologies in micro production an adequate quality assurance plays an even more important role in order to efficiently support the transition of micro production processes from non-robust to stable processes. Thereby, quality assurance faces particular challenges in micro production, which render a reasonable application of common quality methods difficult or even impossible. Consequently, it is essential to develop new concepts or adjust widely applied quality assurance methods in order to support and continuously improve the development- and manufacturing processes in micro production. Within the scope of the Collaborative Research Center (SFB) 499 “Design, production and quality assurance of primary shaped micro components manufactured in ceramic and metallic materials” the approach of the subproject working on the topic quality assurance is threefold: (i) An efficient and process-accompanying information management has been implemented and will be enhanced further on. (ii) Specifically adjusted preventive methods of quality assurance have been developed and applied. (iii) In order to implement an efficient operational quality assurance performance data of the manufacturing processes has been collected and provided. In the future this supply of data will be used to control and improve the manufacturing processes.

A survey on 3D CAD model quality assurance and testing tools

A new taxonomy of issues related to CAD model quality is presented, which distinguishes between explicit and procedural models. For each type of model, morphologic, syntactic, and semantic errors are characterized. The taxonomy was validated successfully when used to classify quality testing tools, which are aimed at detecting and repairing data errors that may affect the simplification, interoperability, and reusability of CAD models.The study shows that low semantic level errors that hamper simplification are reasonably covered in explicit representations, although many CAD quality testers are still unaffordable for Small and Medium Enterprises, both in terms of cost and training time. Interoperability has been reasonably solved by standards like STEP AP 203 and AP214, but model reusability is not feasible in explicit representations.Procedural representations are promising, as interactive modeling editors automatically prevent most morphologic errors derived from unsuitable modeling strategies. Interoperability problems between procedural representations are expected to decrease dramatically with STEP AP242. Higher semantic aspects of quality such as assurance of design intent, however, are hardly supported by current CAD quality testers.     

软件质量保证中不符合问题的探讨与系统实现

软件质量保证过程主要有审计、评审和处理不符合问题等三项主要活动,其中处理不符合问题是软件质量保证的核心.本文明确了多角色参与处理不符合问题的流程,通过对流程的系统分析,在J2EE的B/S应用架构下,以Struts作为表现层框架、Hibernate作为数据持久层框架,设计实现了一个软件质量审计系统的不符合问题处理部分,并利用了XML和JavaMail等技术.该系统职责明确、通过邮件操作提高工作效率,具有良好的可扩展性、实用性和可维护性.     

基于过程控制的软件质量保障平台设计

Practical quality assurance for standards-based, high-availability middleware

Telecommunications technologies are undergoing a major paradigm shift. Standards-based, off-the-shelf components and the Internet are gaining wide acceptance. The success of this move is strongly dependent upon the quality and availability of these technologies.Practical quality assurance in this environment can take advantage of the tools and methods developed when carrier-grade systems for the telecommunications market were being deployed. Besides standard test methods, availability-related methods for redundant hardware and software components are applied. Statistics are available that prove the success of this approach. The statistical data are derived from the deployment of the commercial product RTP⁴ Continuous Services, a standards-based high-availability middleware.Additional momentum has been gained in the Service Availability Forum (www.saforum.org), where the interface standards are validated and certified in independent test processes.

Software quality by management learning from the manufacturing industries

This article looks at software quality from a managerial point of view. Despite the wealth of literature about software quality and how it is measured, high quality software systems are still alarmingly rare. It is suggested that DP management should look to modern production management for a lesson in how to promote quality in their products. This in turn means observing Japanese methods of management, in particular the innovation of the early eighties — the quality circle. Also investigated is the suspicion that today's DP staff would be unwilling to accept changes that management may be forced to adopt to improve the quality of software systems.
