Business processes describe a set of tasks for accomplishing business objectives of an organization. Business applications automate business processes to improve the productivity of business users. Nowadays, the business environment changes fast due to rapid market growth and technological innovations. Business processes are continuously updated to reflect new business initiatives. Business applications are frequently evolved to add features to meet new requirements and fix defects. Quite often, business processes and business applications evolve independently without direct reference to each other. Over time, it becomes more and more challenging to maintain the consistency between a business application and the corresponding business processes. Moreover, the existing development approaches rely on software developers’ craftsmanship to design and implement business applications. Such a development paradigm is inefficient and leads to inconsistency between business processes and business applications. To facilitate the alignment between business applications and business processes, we present an approach that automatically generates software architecture and code skeletons of business applications from business processes. We identify architectural components from business processes by analyzing dependencies among tasks. To verify the achievement of quality requirements, we extend a set of existing product metrics to automatically evaluate the quality of the generated software architecture designs. Eventually, we apply refactoring strategies, such as software architectural styles or design patterns, to optimize the generated software architecture designs and resolve identified quality problems. Moreover, we also present an approach to automatically refine software architecture to design models and code skeletons of business applications. The effectiveness of our proposed approach is illustrated through case studies. / Thesis (Ph.D, Electrical & Computer Engineering) -- Queen's University, 2011-01-30 00:06:34.77

Den här rapporten redovisar produktionsprocessen för en re-design av en webbsida. Kommunikations-byrån Åkesson & Currys webbsida har funnits i över fem år. I dagsläget tycker inte företaget att webbsidan representerar vilka de är, därför var ett led i produktionsprocessen att undersöka hur de ser på sin identitet. Målet var att med en ny vision av Åkesson & Currys identitet producera ett designförslag över en webbsida som presenterar dem på ett representativt sätt. Re-designen ska möjliggöra att användaren blir intresserad av byrån och gärna initierar till en ny kontakt med Åkesson & Curry efter ett besök på webbsidan. Rapporten beskriver mitt tillvägagångssätt genom intervjuer, kravhantering, personas och scenarios. Metoderna har lett till att jag fått en bra grund att stå på när jag utvecklat färgpalett, logotyp och producerat designförslag. Utvecklingen skedde i programmen Adobe Illustrator och Adobe InDesign. Resultatet blev en webbsida som är ljus, varm och intressant – motsatsen till Åkesson & Currys nuvarande webbsida. / This report describes the production process during a re-design of a website. The communications agency Åkesson & Currys website has existed for over five years. In these days the company does not think that the website represents who they are. The aim for me was to examine how they look upon their identity. The goal was to enable a new vision of Åkesson & Curry's identity and come up with design sketches of a website that presents them in a right manner. The re-design enables the user to become interested in the agency and desire to initiate a contact with Åkesson & Curry. The report describes my approach through interviews, lists of goals, personas and scenarios. These methods have led me to a solid starting point when developing the colour palette, logotype and producing the design sketches. The development was done in the programs Adobe Illustrator and Adobe InDesign. The result was a website that is clean, warm and attractive – the opposite of Åkesson & Curry's current website.

Fast fashion retailers have faced a difficulty in translating in-store experiences to online experiences. Although online shopping is increasing, the in-store shopping is still very important for a superior shopping experience. Technology has had a major impact in making multichanneling retail more consistent, although there are gaps that technology can not fill. This study attempted to measure how consistent the customer experiences were online and in-store. Shopping experiences were measured with different concepts such as: flow, usability, interactivity, atmospherics and tactility. These concepts were measured separately in-store and online, in order to be compared. The purpose was to find out which concept is inconsistent so the authors could make recommendations for improvement to fast fashion retailers. The research approach was a mixed method approach and the chosen research design was cross sectional, using quantitative research to corroborate qualitative research findings. The results from a quantitative questionnaire of 263 experienced fast fashion consumers in Sweden show that the consistency varies between the concepts. The qualitative study was done at two occasions on a sample of six interviewees in each focus group, and gave a deeper understanding for why the shopping experience was or wasn't consistent. The qualitative results varied amongst the individuals and show that reasons for being inconsistent are intrusive salesmen, insufficient size measuring tools, long queues, lack of tactility and the most interesting of all: making better return and ordering policies. The future lies in making it easier to order online, in order for the consumer to be able to experience the product in real life, through staff-free fitting rooms and showrooms and such, rather than making the experience better online. The future seems to lie in solving the reverse of the start point of this study, namely translating online to in-store experiences.

Problem: Designing the user experience is a growing trend in product design; however this trend has not greatly benefited people with impairments and disabilities. There are no practical tools to broadly assist with this issue. There is a need for standardized measures to quantify impairment, a model to predict how designs may perform and a need for data regarding how people with impairments interact with consumer technology. Purpose: To conduct a usability analysis with an industry partner on their powered wheelchair controller using participants with varying impairments. The industry partner was seeking better insight into the benefits of formal user testing. Method: Forty consenting adults were given a score representing their level of impairment using six measures from the International Classification of Functioning (ICF). These measures were identified by the researcher to affect interaction with a device. Performance was measured by time taken to complete tasks, errors made, reported task difficulty and reported controller usability. Results: Performance was reduced in participants with a higher ICF score and age. An ICF score less than or equal to 2 was 117 times more likely to not complete the tasks, greater than or equal to 3 was not able to complete the experiment. Age >50 years took an average 79 seconds longer than <35 years to complete a task and reported greater difficulty, more errors and a lower usability for the controller. Implications: Low to moderate levels of impairment has a significantly negative effect on the usability of common devices. Difficulties were mostly cognitive with participants unable to create an accurate mental model of the system. Participants with lower performance tended to be overly optimistic about their abilities. Mistakes were the greatest source of error followed by lapses and almost no reported or observed slip errors. Original Contribution: The ICF has never been used as a metric for usability testing. This study successfully applied the ICF alongside other measures to prove its validity. Based on the results and current literature the Task Process Model was created to provide a simple and practical way to describe the interaction of people completing a task of basic to moderate complexity.

Many countries have formulated their eHealth visions and billions of dollars have been spent on supporting the eHealth development throughout the world. An important part of the development is the electronic patient record (EPR). To enable sharing and increase cooperation between care providers, most Swedish county councils have decided to use a region-wide EPR. The health professionals often experience numerous problems and consider the region-wide EPR to be too generic and require them to tailor their practices instead of the system evolving towards supporting their needs. The aim of the PhD research is to gain knowledge of adoption when deploying and using region-wide health IT systems. This is accomplished by studying, analysing and reflecting upon what region-wide health IT systems are and how professionals use them in their practice. In the research a grounded theory method has been used, which means that the empirical data, not theories and hypotheses, have driven the research process. The data-gathering methods have been interviews, observations, participating in meetings, questionnaires, seminars and conducting literature reviews. In order to be able to improve the adoption, a set of four key principles has been identified: (1) Evolving systems-Engaged users, (2) Treat IT deployment and usage as part of organisational development, (3) Identify, respect and support differences, and (4) Identify what must be customised and what can be centralised. These four principles challenge the traditional way of developing enterprise-wide IT and emphasise the importance that users must engage in the development, procurement and deployment process to identify their similar and unique needs and procedures. It is crucial that both the similarities and uniqueness are respected and supported. The similarities can be supported by a centralised, standardised solution, while uniqueness requires a customised solution. In order to accomplish that, the IT deployment and usage needs to be treated as an important part of the on-going organisational development, and the IT systems must evolve, i.e., be continuously developed in order to engage the users to participate.

Users are increasingly expected to manage complex privacy settings in their normal online interactions. From shopping to social networks, users make decisions about sharing their personal information with corporations and contacts, frequently with little assistance. Current solutions require customers to read long documents or go out of their way to manage complex settings buried deep in the management interfaces, all of which lead to little or no actual control. The goal of this work is to help people cope with the shifting privacy landscape. While our work looks at many aspects of how users make decisions regarding their privacy, this dissertation focuses on two specific areas: the current state of web privacy policies and mobile phone application permissions. We explored consumers' current understanding of privacy in these domains, and then used that knowledge to iteratively design and test more comprehensible information displays. These prototyped information displays should not be seen as final commercially-ready solutions, but as examples of privacy notices that can help users think about, cope with, and make decisions regarding their data privacy. We conclude with a series of design suggestions motivated by our findings.

This thesis presents the development and evaluation of a computerized physician-parent decision support tool for a neonatal intensive care unit (NICU), known as Physician and Parent Decision Support (PPADS). The NICU is a specialized hospital unit that treats very-ill neonates. Many difficult care decisions are made daily for this vulnerable population. The PPADS tool aims to augment current NICU decision-making by helping parents and physicians make more informed decisions, improving physician-parent communication, increasing parent decision-making satisfaction, decreasing conflict, and increasing decision efficiency. The development of the PPADS tool followed a five-step methodology: assessing the clinical environment, establishing the design criteria, developing the system design, implementing the system, and performing usability testing. Usability testing of the PPADS tool was performed on neonatologists and on parents of neonates who have graduated (survived) from a tertiary level NICU. The usability testing demonstrated the usefulness and ease of use of the tool.

In this thesis, we present a tool that is an extension of the NAVIRE Framework and used in remote environment exploration and navigation. It is available for end users on everyday devices such as desktops and mobile devices. The tool offers the characteristic of being cross-platform and easy to use and manipulate. Cubic panoramas that are generated by the NAVIRE Framework are loaded in the tool and rendered in 3D space on the user’s device. The 3D panoramas are interactive by allowing the user to view the scene in all direction, move from one scene to another or through interaction with augmented objects. The tool is geared to be interactive in the most natural and intuitive fashion using the inputs available in the different devices of the end-user.
