“…Scenarios are an effective means of communication between users and stakeholders when requirements have to be identified from real world experiences (Sutcliffe, 2003). In agile software development methods, they are referred to as user stories (Riedemann and Freitag, 2009). Four researchers were asked to explain to us how they collect and use data at the neighbourhood level for their urban design projects.…”

<p><strong>Abstract.</strong> Urban designers collect information about a city or neighborhood, design improvements so that the city is functional and pleasant to live in, and communicate these improvements to relevant stakeholders. The use of space and the spatial relationships between physical features play a significant role in urban design, therefore much of the information that is collected and manipulated is georeferenced. We followed a scenario-based approach for collecting requirements for urban design projects. Functional and non-functional requirements were categorized into data collection, data storage and management, and data visualization. Subsequently, we reviewed and evaluated open source geospatial tools that can be used for the collection, storage, manipulation and visualization of geospatial data in urban design projects. Based on the evaluation, we propose an open geospatial toolbox for urban design projects. The results are equally applicable for researchers and professionals in other disciplines who collect data at the neighbourhood level.</p>

Engineering system architectures for complex systems involves the tasks of analyzing architectural drivers, identifying architectural concerns, identifying valid architecture candidates, and evaluation of alternatives. One problem to overcome when architecting a system is the identification of valid of architectural candidates. We have developed a step-wise method for performing system architecture analysis and tested it on a subsystem in a project developing a drive system for heavy automotive applications. In this paper we present the complete method of nine steps for engineering an architecture and we elaborate in detail on the procedure to identify architectural candidates based on previously identified architectural drivers. We present a diagram depicting the proposed information model, its concepts and their relationships. In addition, the expectations on such a method as expressed by practitioners have been elicited, and we elaborate on the validity by examining how well the method indicate fulfillment. Our conclusion is that the proposed method does not fail to deliver on any of the needs and this gives an indication of usefulness. When identifying architectural candidates it is important to use proper criteria in the process. Our conclusion is that the practitioners should focus on candidates that affect the system at hand (within system boundaries), and on the candidates that address the architecturally significant system use. This is reflected in our method where we prescribe evaluation of the design candidates by validating that they solve only the right problem and by ensuring that they address the system at hand.

Purpose -The purpose of this paper is to explore and analyze the views of top financial executives on the information systems (IS) in their organizations and to study the critical information technology issues facing organizations. Specifically, it aims to study critical issues over the period 2006 to 2010, as well as the effect of company size on the criticality of issue. Design/methodology/approach -The paper uses an analysis of secondary data obtained from the 2006 and 2010 Financial Executives International (FEI) comprehensive survey-based research on technology issues for financial executives. The study was conducted by the FEI and in conjunction with Computer Sciences Corporation in 2006. Factorial analysis of variance (ANOVA) and other statistical methods are used. Findings -The findings confirm critical issues that are facing organizations today. The study also finds that company size generally does not play a significant role in the criticality of information technology (IT) issues and that generally, there has been variation in the relative importance of issues between 2006 and 2010.Research limitations/implications -The study can be used as a basis for further exploration on critical IT issues, as well as the influences on company size on criticality of issues. It can also serve as a preliminary model to analyze firm IS over time. Limitations of the study include that the only group included in the survey were financial executives and the study is primarily based on US company responses. Practical implications -The findings can be used to guide management teams in emphasizing areas that need attention and are of critical importance to all organizations. The article is extremely topical and useful for practitioners in understanding what are the major issues facing IT today. The longitudinal analysis and size study are particularly important in confirming the importance of the relevant IT issues. Originality/value -The paper analyzes a large current sample set which empirically reviews a cross-section of major corporations, IS departments and their returns. In addition, it begins to explore longitudinal and size effects on critical IT issues
