abstract: The e-Retail industry has grown rapidly over the last few years and is projected to continue its upward trend as consumers shift from traditional channels to online channels. In March 2010, Forrester Research forecasted that online retail sales will grow by 10% a year for the next 5 years and e-Retail sales will amount to $249 billion by 2014. With intense competition for market share and profits, information systems and technology (IST) sourcing decisions are becoming increasingly important to e-Retail firms to support continued growth and market responsiveness. There are several aspects for e-Retailers to consider when formulating its IST sourcing strategy. Whether to choose make versus buy for technology assets and services has been addressed in both strategy and IS literature (Handfield et al. 1999, Leiblein et al. 2002, Wade and Hulland, 2004). Then there is the follow-up question of selecting a best-of-breed strategy or tighter partnership with a select group of vendors (Clemons et al. 1993, Kauffman and Tsai 2009). Few studies have looked at IST sourcing or proposed models and frameworks for evaluating IST sourcing decisions (Saarinen and Vepsalainen, 1994). Furthermore, these existing studies mainly address the antecedents of the decisions but not so much on their performance effects (Kauffman and Tsai 2009; Smith et al., 1998). The goal of this study is to extend the knowledge of IST sourcing for e-Retailers, a topic which has received limited attention (Kishore et al., 2004), by addressing a core problem: How should an e-Retailer develop and implement its IST sourcing strategy to accommodate the increase in consumer demand and IT complexity but still achieve high performance? The study introduces two theoretical models to examine organizational factors that influence an e-Retailer's IST sourcing strategies of make versus buy and partnership versus best-of-breed. The proposed models are tested using a panel data set of 307 e-Retail firms over the period of 2006 to 2010. The study opens up the black box of internal firm operations by introducing a granular view of IST sourcing decisions at both the value chain and e-Commerce architecture levels and examining the performance impacts of these strategic choices. This in-depth look at IST sourcing has yet to be explored in the literature. / Dissertation/Thesis / Ph.D. Information Management 2012

The textile industry is currently operating in an unsustainable manner that is based on overproduction and wasteful, resource-draining practices. Therefore, recently, the concept of circular economy has been presented as a possible solution and a way forward. Changing linear economy business practices and basing them on the circular economy concept is anticipated to solve social and environmental problems while maintaining economic growth. However, fashion retail value chains essentially depend on the logic of mass production, fast fashion, and linear take-make-dispose models. Presently, circular initiatives in this context are rather limited. This thesis posits that circular business model (CBM) scalability is an important factor in the transition to a circular economy in the fashion retail value chain, and thus, a more sustainable fashion industry. Therefore, the purpose of this thesis is to further the understanding of CBM scalability in the context of fashion retail value chains. This includes expanding the notion of scalability to cover a more holistic perspective that goes beyond increasing production output solely for economic gains. Additionally, this involves enhancing the understanding of the required specific resources and capabilities that CBMs must have or develop to overcome challenges and increase their potential for scalability. Accordingly, this thesis covers three papers that utilise qualitative methods wherein archival material, such as peer reviewed journal articles and industry reports, as well as interviews with practitioners are used. Moreover, the extension of the notion of business model scalability goes beyond the boundary of the organisation and encompasses three different perspectives, namely, efficiency, adaptability, and altruism. In addition to this, three areas that challenge CBM scalability are identified. These challenges stem from different business model design themes and can be described as (i) inefficiency, (ii) lack of know-how and out-of-the-box solutions, and (iii) unfamiliarity resulting in scepticism and dissonance with current practices and policy. Finally, the thesis contributes to the CBM literature by utilising the theoretical lenses of resource-based theory and dynamic capabilities theory to identify resources and dynamic capabilities that are strategically important for scaling CBMs. This thesis expands the notion of scalability by going beyond the boundary of the single organisation as well as including a triple bottom line perspective, thus providing an important addition to the understanding of the scalability of CBMs. / Textilindustrin verkar för närvarande på ett ohållbart sätt som bygger på överproduktion och resurskrävande metoder. Cirkulär ekonomi som koncept, har därför nyligen presenterats som en möjlig lösning på de problem som industrin står inför. Genom att frångå linjära praxis och istället bygga affärsmetoder på cirkulär ekonomi förväntas sociala och miljömässiga problem kunna lösas samtidigt som den ekonomiska tillväxten bibehålls. Modeindustrins värdekedjor bygger dock fortfarande huvudsakligen på massproduktion, fast fashion och linjära take-make-dispose-modeller. Cirkulära initiativ är i detta sammanhang ganska begränsade. Denna avhandling framhäver därför, att skalbarhet av cirkulära affärsmodeller är en viktig faktor i övergången till en cirkulär ekonomi, och därmed en mer hållbar modeindustri. Syftet med denna avhandling är följaktligen att öka förståelsen för skalbarhet av cirkulära affärsmodeller inom modebranschens värdekedjor, med fokus på detaljhandeln. Innefattat i detta är ett utvidgat begrepp av skalbarhet, som inkluderar mer än enbart ökad produktion för ekonomisk vinst. Till detta hör även en ökad förståelse av de specifika resurser och förmågor som cirkulära affärsmodeller måste ha eller utveckla för att övervinna utmaningar och bli mer skalbara. Avhandlingen omfattar tre artiklar som använder kvalitativa metoder där arkivmaterial, såsom refereegranskade journalartiklar och branschrapporter, samt intervjuer med personer verksamma i branschen, används. Resultatet påvisar att cirkulära affärsmodellers skalbarhet går bortom organisationens gränser och omfattar tre olika perspektiv: effektivitet, anpassningsförmåga och altruism. Utöver detta identifieras tre områden som speciellt utmanande för skalbarheten. Dessa utmaningar härrör från två olika designteman av affärsmodeller och kan beskrivas som (i) ineffektivitet, (ii) bristande kunskap och brist på färdiga lösningar, och (iii) obekantskap som resulterar i skepsis och dissonans med nuvarande praxis och policy. Slutligen bidrar avhandlingen till litteraturen om cirkulära affärsmodeller genom att använda resursbaserad teori och dynamiska förmågor-teori för att identifiera resurser och dynamiska förmågor som är strategiskt viktiga för skalbarhet av cirkulära affärsmodeller. Avhandlingen bidrar således till kunskapen om cirkulära affärsmodellers skalbarhet genom att utvidga begreppet till att även innefatta aktiviteter som sträcker sig utanför den enskilda organisationen, samt inkludera ett triple bottom line-perspektiv. / <p>Delvis finansierat av Handelsbankens forskningsstiftelser (Jan Wallander and Tom Hedelius Foundation, Tore Browalds Foundation)</p>
