We look at whether the use of UML class diagrams, as opposed to using no modeling notation, influences code change proneness. Furthermore, using five design metrics we measure the quality of UML class diagrams and explore its correlation with code change proneness. Based on a UML model of an industrial system and multiple snapshots of the implementation code, we have found that at the system level the change proneness of code modeled using class diagrams is lower than that of code that is not modeled at all. However, we observe different results when performing the analysis at different system levels (e.g., subsystem and sub subsystem). Additionally, we have found significant correlations between class diagram size, complexity, and level of detail and the change proneness of the implementation code.","PeriodicalId":123055,"journal":{"name":"EESSMod '12","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126496473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We address the problem of modelling the business processes by means of UML activity diagrams, and present five styles differing in the precision level, from the Ultra-Light style, where the nodes and the edges of the activity diagram are decorated by freely-formed text, to precise styles where instead OCL and UML actions are used. Then, we propose a practical empirical method for choosing the most suitable style depending on the context in which the models will be used (why, when, where, how long, by whom).","PeriodicalId":123055,"journal":{"name":"EESSMod '12","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131993987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in some cases, these diagrams contain a lot of information. This makes it hard for software maintainers to use them to understand a system. In this paper, we aim to discover how to simplify class diagrams in a such way that they make systems easier to understand. To this end, we performed a survey to analyze what type of information software developers find important to include or exclude in order to simplify a class diagram. This survey involved 32 software developers with 75% of the participants having more than 5 years of experience with class diagrams. As the result, we found that the important elements in a class diagram are class relationship, meaningful class names and class properties. We also found that information that should be excluded in a simplified class diagram is GUI related information, private and protected operations, helper classes and library classes. In this survey we also tried to discover what types of features are needed for class diagram simplification tools.","PeriodicalId":123055,"journal":{"name":"EESSMod '12","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133483586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thereby, accuracy, i.e., the amount of correctly performed tasks divided by the number of total tasks, is usually used to assess performance. Even though accuracy is widely adopted, it is connected to two often overlooked problems. First, accuracy is a rather insensitive measure. Second, for tasks of low complexity, the measurement of accuracy may be distorted by peculiarities of the human mind. In order to tackle these problems, we propose to additionally assess the subject's mental effort, i.e., the mental resources required to perform a task. In particular, we show how aforementioned problems connected to accuracy can be resolved, that mental effort is a valid measure of performance and how mental effort can easily be assessed in empirical research.","PeriodicalId":123055,"journal":{"name":"EESSMod '12","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123436299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Micro-businesses also have several resource restrictions. These ambiguities and constraints make software research and development difficult in the micro-business domain. Component-based development offers advantages for the software of micro-businesses. The reuse of components for common requirements minimizes resource consumption in their software projects. This paper provides a working definition for micro-businesses, observations of their behavior, working micro-business behavior patterns, and examples of real world applications on how the patterns help in software development through requirements. The micro-business behavior patterns are associated with components that will be used later on in the development of micro-business software systems.","PeriodicalId":123055,"journal":{"name":"EESSMod '12","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128945435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have defined the Feature Assembly Modelling, a feature modelling technique that allows to model variability in software adopting a multi perspective approach. Furthermore, the approach allows modelling software by combining both variability and reusability, i.e. we have developed an approach to take reusability into account while defining new software. To support the approach, we have also developed an information retrieval framework that provides an interactive visualization of the feature models. The visualization allows users to explore and query the existing models. In this paper, we report on our experience in introducing this variability modelling approach into a small-scale software company. This experience was very useful for both parties. The company was able to uncover the structure of their software and the modelling exercise provided them better insight in their products. For us, it has helped to better understand the needs of companies, to evaluate the usability of our Feature Assembly approach and the associated learning curve, as well as revealing its current limitations. Moreover, as we are aware of the fact that classical feature modelling is not yet a practice adopted by companies, it was interesting to see that our approach was well accepted and appreciated by the company.","PeriodicalId":123055,"journal":{"name":"EESSMod '12","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116569682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
