Submitted in partial fulfillment for Masters in Fashion, Durban University of Technology, Durban, South Africa, 2016. / In my practise-based action research self-study I have developed ways in which to improve my practice as a bridal-gown designer in a highly-competitive and import-driven bridal-gown market. My earnest intent was to improve my practice using action research methods whilst simultaneously developing a solution through critical reflection and practice-based approaches as an economically-sustainable designer of bespoke, cost-effective, competitively-priced bridal gowns. I realised the potential for professional influence and positive economic growth through entrepreneurial thinking, not only for me but for others; it was this which cemented a sense of values in me as an action researcher. I have displayed a healthy marriage between equally important views of practice as theory and the theory as practice. I explored relevant literature that would validate my practice and aid in answering my critical questions, which became evident as validation chapters in my study. Carrying out internships with three bridal gown designers opened my eyes to the real world of business, a sense of theory as practice, where I could see, first-hand, the effects the import industry had on local designers and what they were doing to survive. The conceptualisation of foundational bridal blocks was a solution to save time in my own creative process so that I could produce cost-effective bridal gowns at a competitive price, in a sustainable manner. Once I had explored and created my own interpretation of the foundation block concept that transformed into a small collection of bridal gowns, I used the foundation blocks as a starting point to design bridal gowns for ‘real’ bridal clients. My study is personal in nature; by way of using self-study methods and also the personal ‘one-on-one’ connection I have with my ‘real’ bridal clients. I extended this ‘personal factor’ by holding a public exhibition to which I invited my friends, family, the public and my peers to view and give critical feedback on my work as a bridal gown designer. / M

No / Purpose ¿ To examine the psychometric properties and construct validity of the general decision making style (GDMS) questionnaire in two UK samples. Design/methodology/approach ¿ The GDMS takes the form of a self-report questionnaire which identifies five decision making styles: rational, intuitive, dependent, avoidant, and spontaneous. It was administered to samples of business studies undergraduates in two UK business schools. Analyses included scale reliabilities, test-re-test reliability, and both exploratory and confirmatory factor analyses. Findings ¿ The instrument's internal and temporal consistencies were generally sound. Consistent with earlier studies, analyses undertaken on the two samples independently were generally supportive of a five factor model of decision making style. No relationships with gender or year of study were observed.

Elon saknar ett effektivt system vad gäller artikelplacering på lagret. Inkommande artiklar placeras på de platser där möjligheten finns att ta emot hela den inkommande volymen. Syftet med examensarbetet har två delar. En del är att ta fram en tydlig metod för Elon att använda vid en frekvensläggning samt att genomföra den valda metoden för 12 månader. Den andra delen är att simulera den totala körsträckan för truckförarna före och efter en frekvensläggning för det första kvartalet år 2021 med målet att uppnå en minskad körsträcka på 10 %. Arbetet ska även resultera i en färdig programmeringskod i Python som Elon ska kunna använda vid framtida simuleringar. Arbetet inleddes med en litteratursökning av relevanta metoder och tekniker som ska vara till grund för den frekvensläggning som genomförs i arbetet. De forskningsmetoder som identifierades och valdes var Design Research Methodology samt datainsamlingsteknikerna Litteraturstudie, Dokumentstudie, Intervju och Observation. Efter att en litteraturstudie genomförts valdes metoden ABC-analys som metod för frekvensläggning. Arbetet resulterade i en metod för frekvensläggning som innehåller fem steg som företaget bör följa och som beskrivs djupare i rapporten. ABC-analysen resulterade i att samtliga artiklar på lagret klassificerades i A-, B- eller C-klass efter uttagsfrekvens och ett platsbehov för varje klass beräknades. Den simulerade plockningen efter en frekvensläggning resulterade i en minskad körsträcka på 21,09 %. Arbetet kan utvecklas ytterligare genom att ta hänsyn till vilka portar det körs mer frekvent till, identifiera artiklar som ofta körs tillsammans och placera nära varandra, anpassa lagret efter kampanjvaror och dess tidsperioder samt om möjligt kunna torrköra plockning efter genomförd frekvensläggning i lagrets WMS som då resulterar i en noggrannare simulering. / The company Elon Group AB lacks an effective method when it comes to product placement within the warehouse. As of now incoming products are placed where storage space is available. The purpose of this work can be divided into two parts. One part is to create a method that Elon can use when placing their products using picking frequency, this method will be used in practice during this thesis when placing products using picking frequency for a period of 12 months. The second part of this thesis is to simulate the accumulated distance forklift drivers have driven before and after slotting by picking frequency for a period of 3 months. The goal is to accomplish a 10% decrease in driving distance after slotting has been made. The simulation requires a code in the programming language Python which is part of the thesis. The work started with a literature review to help choose the right methods. The methods that were identified and used were Design Research Methodology, literature study, document study, interviews and observations. After the literature study was made an ABC-analysis was chosen specifically as the method for conducting the slotting. The work resulted in a five step-method. The ABC-analysis resulted in all of the products being given a class (A, B or C) and the required number of storage bins for the different classes were calculated. The simulation showed a decreased driving distance of 21,09 %. The work can develop by taking into account that the exit-ports in practice do not ship out an equal amount of goods, identifying which products that are often picked together and placing them near each other, taking into account campaign products and if possible dryrun the warehouse WMS after slotting to obtain more accurate data.

Due to the global energy crisis there is a vast increase in demand for heat exchangers that reduces the energy consumption during energy transfer between mediums. The current manufacturing process for brazed heat exchangers at the world leading man-ufacturer, Alfa Laval, involves a partial assembly process called Plastic Flange Defor-mation (PFD). The current PFD process is conducted manually and is completely dependent on human presence. The great increasing demand for heat exchangers world wide creates the need for a more efficient and sustainable solution for the PFD process. To meet the capacity increase a higher level of automated process is required. The key areas to investigate in this thesis are quality control and component handling within the PFD process. Concepts for the key areas will be developed and two new concepts for the automated PFD cell will be presented. The used method for this thesis is a combination of the outline of Design Research Methodology (DRM) and the Analytical Hierarchy Approach (AHP) for the decision making process for the final PFD cell concepts. The Developed key area concepts are validated with either physical prototypes or virtually with solid mechanics analysis. The result showed that there exist different solutions and possibilities for handling the large variety of components within the PFD process. The quality controls are solved with a combination of vision systems and actuator motors. The first concept for an automated PFD cell consists of two collaborative robots with specially designed grippers, that allow the robots to handle all the components and perform the quality controls. The cell contains specially designed racks for loading and unloading the pressure plates and frame plates. The second concept is a larger more complex solution with four industrial robots, and with a cycle time half as low as the first concept. Both cells contain the same developed key area concepts. The AHP suggests the second concept with respect to the weighting of the criteria from the stakeholders. The conclusion of this work is that there are opportunities to automate and improve the PFD process using robotics and automated quality controls. The presented concepts can help Alfa Laval meet the increasing demand for heat exchangers in an efficient and sustainable way. / På grund av den globala energikrisen ökar efterfrågan på värmeväxlare som minskar energiförbrukningen genom energiöverföring mellan medium. Alfa Laval är ett världsledande företag som bland annat tillverkar lödda värmeväxlare, där tillverkn-ingsprocessen för närvarande innefattar en delmonteringsprocess som kallas "Plastic Flange Deformation" (PFD). Den nuvarande PFD-processen utförs manuellt och är helt beroende av mänsklig närvaro. Den ökande efterfrågan på värmeväxlare skapar behovet av en mer effektiv och hållbar lösning för PFD-processen. För att möta kapacitetsökningen krävs en högre automatiseringsnivå. De viktigaste områdena att undersöka i denna avhandling är kvalitetskontroll och hantering av komponenter inom PFD-processen. Koncept för dessa områden kommer att utvecklas och två nya koncept för den automatiserade PFD-cellen kommer att presenteras. Metoden som används i denna avhandling är en kombination av Design Research Methodology (DRM) och Analytical Hierarchy Approach (AHP) för beslutsfattandet av de slutliga PFD-cell koncepten. De utvecklade koncepten för nyckelområdena valideras med fysiska prototyper eller virituellt genom hållfasthetsanalys. Resultaten visade att det finns olika lösningar och möjligheter för hantering av den stora variationen av komponenter inom PFD-processen. Kvalitetskontrollerna utförs med en kombination av visionsystem och aktuatorer. Det första konceptet för en automatiserad PFD-cell består av två kollaborativa robotar med speciellt utformade gripare som tillåter robotarna att hantera alla komponenter och utföra kvalitetskontroller. Cellen innehåller speciellt utformade stativ för lastning och avlastning av tryckplattor och stativplattor. Det andra konceptet är en större och mer komplex lösning med fyra industrirobotar och med en cykeltid som är häften så låg som det första konceptet. Båda cellerna innehåller samma utvecklade koncept för nyckelområdena. AHP föreslår det andra konceptet med hänsyn till viktningen av kriterierna från intressenterna. Slutsatsen av detta arbete är att det finns möjligheter att automatisera och förbättra PFD-processen med hjälp av robotteknik och automatiserade kvalitetskontroller. De presenterade koncepten kan hjälpa Alfa Laval att möta den ökande efterfrågan på värmeväxlare på ett effektivt och hållbart sätt.

Large software organizations handle many customer support issues every day in the form of bug reports, feature requests, and general misunderstandings as submitted by customers. Strategies to gather, analyze, and negotiate requirements are comple- mented by efforts to manage customer input after products have been deployed. For the latter, support tickets are key in allowing customers to submit their issues, bug re- ports, and feature requests. Whenever insufficient attention is given to support issues, there is a chance customers will escalate their issues, and escalation to management is time-consuming and expensive, especially for large organizations managing hundreds of customers and thousands of support tickets. This thesis provides a step towards simplifying the job for support analysts and managers, particularly in predicting the risk of escalating support tickets. In a field study at our large industrial partner, IBM, a design science methodology was employed to characterize the support process and data available to IBM analysts in managing escalations. Through iterative cycles of design and evaluation, support analysts’ expert knowledge about their customers was translated into features of a support ticket model to be implemented into a Ma- chine Learning model to predict support ticket escalations. The Machine Learning model was trained and evaluated on over 2.5 million support tickets and 10,000 escalations, obtaining a recall of 79.9% and an 80.8% reduction in the workload for support analysts looking to identify support tickets at risk of escalation. Further on- site evaluations were conducted through a tool developed to implement the Machine Learning techniques in industry, deployed during weekly support-ticket-management meetings. The features developed in the Support Ticket Model are designed to serve as a starting place for organizations interested in implementing the model to predict support ticket escalations, and for future researchers to build on to advance research in Escalation Prediction. / Graduate

The full enforcement of the General Data Protection Regulation (GDPR) that began on May 25, 2018 forced any organization that collects and/or processes personal data from European Union citizens to comply with a series of stringent and comprehensive privacy regulations. Many software organizations struggled to comply with the entirety of the GDPR's regulations both leading up and even after the GDPR deadline. Previous studies on the subject of the GDPR have primarily focused on finding implications for users and organizations using surveys or interviews. However, there is a dearth of in-depth studies that investigate compliance practices and compliance challenges in software organizations. In particular, small and medium enterprises are often neglected in these previous studies, despite small and medium enterprises representing the majority of organizations in the EU. Furthermore, organizations that practice continuous integration have largely been ignored in studies on GDPR compliance. Using design science methodology, we conducted an in-depth study over the span of 20 months regarding GDPR compliance practices and challenges in collaboration with a small, startup organization. Our first step helped identify our collaborator's business problems. Subsequently, we iteratively developed two artifacts to address those business problems: a set of privacy requirements operationalized from GDPR principles, and an automated GDPR tool that tests these GDPR-derived privacy requirements. This design science approach resulted in five implications for research and for practice about ongoing challenges to compliance. For instance, our research reveals that GDPR regulations can be partially operationalized and tested through automated means, which is advantageous for achieving long term compliance. In contrast, more research is needed to create more efficient and effective means to disseminate and manage GDPR knowledge among software developers. / Graduate

According to Dorst and Dijkhuis (1995) the two principal paradigms governing design activity discourse, are Simon's rational problem solving, and Schon's theory of design as a 'reflective conversation with the situation'. The rational problem solving view, that a fixed problem space structures design activity, has reduced the designer to a 'missing person' within design activity research (Dorst & Reymen 2004). This thesis aims to highlight the agency of the designer in structuring and motivating socially situated design activity. Dorst's (2006) framework of 'design paradoxes' suggests that design problems are evolving and unknowable. Design situations are determined through the designer's reinterpretation of the social discourses underpinning design situations, in a similar way to 'problem setting' within 'reflection-in-action' (Schon 1983). While Dorst suggests interpretation relies on intuition, problem setting relies on 'professional artistry' which is 'bounded' by the 'appreciative system' (personal knowledge, values and beliefs) and is essentially 'learnable' (Schon 1983). This thesis explores the correspondence between Schon's theory and contemporary frameworks including 'design paradoxes' (Dorst 2006), 'designerly ways of knowing' (Cross 1982), 'organising principles' (Rowe 1987), and 'creative problem construction' (Mumford et al 2004). It investigates the agency of the designer as evidenced in the use of the 'appreciative system'. This is elucidated using case study analysis of a novice designer, within a tertiary design degree. The case reveals the structured and motivated use of the designer's appreciative system. It indicates the deployment of 'appreciative goals' are fundamental to the 'linking behaviour of designers' (Dorst 2006), enabling design to begin in the absence of 'repertoire' or domain knowledge (Schon 1983), and the acquisition of new repertoire knowledge. These emergent findings offer new pedagogical perspectives both in terms of design expertise, which is normally associated with domain knowledge, and educating domain independent, multidisciplinary designers. Frames or similar 'organising principles' operate in most design fields, and create a 'principle of relevance' for knowledge from multiple domains and disciplines (Buchanan 1992). An awareness and acknowledgement of the objective function of subjective personal and social knowledge is essential in order to locate the 'missing' designer and understand innovative design activity.
