As a practical opportunity for educating Japanese young developers in the field of embedded software development, a software design contest involving the design of software to automatically control a line-trace robot, and conduct running performance tests was held. In this paper,we give the results of the contest from the viewpoint of software quality evaluation. We create a framework for evaluating the software quality which integrated design model quality and the final system performance, and conduct analysis using the framework. As a result of analysis,it is found that the quantitative measurement of the structural complexity of the design models bears a strong relationship to qualitative evaluation of the design conducted by judges. It is also found that there is no strong correlation between design model quality evaluated by the judges and the final system performance. For embedded software development, it is particularly important to estimate and verify reliability and performance in the early stages,using the model. Based on the analysis result,we consider possible remedies with respect to the models submitted,the evaluation methods used and the contest specifications. In order to adequately measure several non-functional quality characteristics including performance on the model,it is necessary to improve the way of developing robot software (such as applying model driven development)and reexamine the evaluation methods.

This tutorial focuses on applying aspect-oriented software development (AOSD) concepts beyond the programming stage of the software development life cycle. Using concrete methods, tools, techniques and notations we discuss how to use AOSD techniques to systematically treat crosscutting concerns during requirements engineering (RE), architecture design and detailed design as well as the mapping between aspects at these stages. With a clear focus on composition, modelling, trade-off analysis and assessment methods, the tutorial imparts an engineering ethos for translation into day-to-day processes and practices.

This paper presents the lessons learnt during the analysis of the corporate databases developed by IBM Global Services (Australia). IBM is rated as CMM level 5. Following CMM level 4 and above practices, IBM designed several software metrics databases with associated data collection and reporting systems to manage its corporate goals. However, IBM quality staff believed the data were not as useful as they had expected. NICTA staff undertook a review of IBM's statistical process control procedures and found problems with the databases mainly due to a lack of links between the different data tables. Such problems might be avoided by using M3P variant of the GQM paradigm to define a hierarchy of goals, with project goals at the lowest level, then process goals and corporate goals at the highest level. We propose using E-R models to identify problems with existing databases and to design databases once goals have been defined.
本文介绍了对IBM Global Services (Australia)开发的企业数据库进行分析的经验教训。IBM被评为CMM 5级。遵循CMM级别4及以上的实践，IBM设计了几个带有相关数据收集和报告系统的软件度量数据库，以管理其公司目标。然而，IBM的质量人员认为，这些数据并不像他们预期的那样有用。国家统计协委会工作人员审查了IBM的统计过程控制程序，发现数据库存在问题，主要原因是不同数据表之间缺乏联系。这样的问题可以通过使用GQM范例的M3P变体来定义目标层次结构来避免，其中项目目标在最低级别，然后是过程目标和公司目标在最高级别。我们建议使用E-R模型来识别现有数据库的问题，并在目标确定后设计数据库。

Gaining higher level evolutionary information about large software systems is a key challenge in dealing with increasing complexity and decreasing software quality. Software repositories such as modifications, changes, or release information are rich sources for distinctive kinds of analyses: They reflect the reasons and effects of particular changes made to the software system over a certain period of time. If we can analyze these repositories in an effective way, we get a clearer picture of the status of the software. Software repositories can be analyzed to provide information about the problems concerning a particular feature or a set of features. Hidden dependencies of structurally unrelated but over time logically coupled files exhibit a high potential to illustrate software evolution and possible architectural deterioration. In this tutorial, we describe the investigation of software evolution by taking a step towards reflecting the analysis results against software quality attributes. Different kinds of analyses (from architecture to code) and their interpretation will be presented and discussed in relation to quality attributes. This will show our vision of where such evolution investigations can lead and how they can support development. For that, the tutorial will touch issues such as meta-models for evolution data, data analysis and history mining, software quality attributes, as well as visualization of analysis results.

A plethora of aspect mechanisms exist today. All of these diverse mechanisms integrate concerns into artifacts that exhibit crosscutting structure. What we lack and need is a characterization of the design space that these aspect mechanisms inhabit and a model description of their weaving processes. A good design space representation provides a common framework for understanding and evaluating existing mechanisms. A well-understood model of the weaving process can guide the implementor of new aspect mechanisms. It can guide the designer when mechanisms implementing new kinds of weaving are needed. It can also help teach aspect-oriented programming (AOP). In this paper we present and evaluate such a model of the design space for aspect mechanisms and their weaving processes. We model weaving, at an abstract level, as a concern integration process. We derive a weaving process model (WPM) top-down, differentiating a reactive from a nonreactive process. The model provides an in-depth explanation of the key subprocesses used by existing aspect mechanisms.

Fred Brooks' seminal book, "The Mythical Man-Month" (MMM) is a firmly established classic in software engineering. Many of us feel compelled to use this work to help our students appreciate and put into practice the fundamental software engineering concepts contained between its covers. This often amounts to using "passive" lesson plans such as required readings followed by lectures and exams; these rarely fully satisfy our learning objectives. Rather, students often have mixed reactions to MMM with the result that it has little impact on their attitudes and practices, both in and out of the classroom. This paper outlines a more active approach to incorporating MMM into the classroom, one that we have refined over 6 years, at multiple universities and in both graduate and undergraduate courses. It includes learning objectives, a lesson plan, sample materials, an implementation discussion, and an evaluation of the approach's impact.
Fred Brooks的开创性著作《人月神话》(MMM)是软件工程领域的经典著作。我们中的许多人都觉得有必要使用这本书来帮助我们的学生理解和实践书中包含的基本软件工程概念。这通常相当于使用“被动”的课程计划，比如在授课和考试之后进行必读;这些很少能完全满足我们的学习目标。相反，学生们对MMM的反应往往是褒贬不一，结果是它对他们在课堂内外的态度和做法几乎没有影响。本文概述了一种将MMM纳入课堂的更积极的方法，这是我们在6年多的时间里在多所大学的研究生和本科生课程中改进的一种方法。它包括学习目标、课程计划、样本材料、实施讨论以及对方法影响的评估。

This tutorial introduces dynamic web services as a solution to cope with the dynamism and flexibility required by many modern software systems. Current technologies (WSDL, WS-BPEL, etc.) have proven insufficient in addressing these issues; however, they remain a good starting point for the analysis of the current situation and for building for the future.The core part of the tutorial analyzes ---by looking at available technologies and prominent research proposals---the deployment and execution of these applications within three separate phases: a composition phase, to discover available services and implement the desired behavior, a monitoring phase, to understand if a given service is behaving correctly (with respect to both functional and non-functional requirements), and a recovery phase, to react to anomalies by means of suitable replanning or recovery strategies.In conclusion, the tutorial summarizes the main topics, presents a list of still-to-be-solved problems, and highlights possible directions for future research.

We present emerging results from our work on termination analysis of software systems. We have designed a static analysis algorithm which attains increased precision and flexibility by issuing queries to a theorem prover. We have implemented our algorithm and initial results show that we obtain a significant improvement over the current state-of-the-art in termination analyses. We also outline how our approach, by integrating theorem proving queries into static analyses, can significantly impact the design of general-purpose static analyses.

A stress test methodology aimed at increasing chances of discovering faults related to network traffic in distributed systems is presented. The technique uses the UML 2.0 model of the distributed system under test, augmented with timing information, and is based on an analysis of the control flow in sequence diagrams. It yields stress test requirements that are made of specific control flow paths along with time values indicating when to trigger them. Different variants of our stress testing technique already exist (they stress different aspects of a distributed system) and we focus here on one variant that is designed to identify and to stress test the system at the instant when data traffic on a network is maximal. Using a real-world distributed system specification, we design and implement a prototype distributed system and describe, for that particular system, how the stress test cases are derived and executed using our methodology. The stress test results indicate that the technique is significantly more effective at detecting network traffic-related faults when compared to test cases based on an operational profile.
