Requirements can change in various ways during the course of a project, and the effect of change on the outcome can differ widely. In this paper we study the effect of different patterns of requirements discovery on a software project. Using a validated model of software process we show that the effect on the total effort, the completion time and the workforce deployment patterns can be counter intuitive as different patterns of change impact software project dynamics in different ways. The insight into the relationship between requirements discovery pattern and project outcome can help managers decide appropriate risk mitigation policy and workforce augmentation plan.","PeriodicalId":211759,"journal":{"name":"2009 42nd Hawaii International Conference on System Sciences","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124370452","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}

The first examines the factors influencing an individual's decision to accept a new technology. The second stream deals with the impact of culture on the development and use of information technology; and the third stream is directed toward the transfer of information technology from one country or context into another. While these three streams have attempted to theorize and empirically explain the factors influencing information technology adoption within a new environment, they have largely been used separately and tested within the context of advanced economies. In this paper we attempt to integrate all three in examining the introduction of telemedicine technology in medically underserved communities. The results suggest that the interaction effects of the factors derived from all theories provide a better explanation of technology introduction in medically underserved communities.","PeriodicalId":211759,"journal":{"name":"2009 42nd Hawaii International Conference on System Sciences","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114352093","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}

In order to reduce their maintenance cost of internal IT clusters, many hard- and software providers reconsider to offer these resources in grid and cloud markets. However, participants in these markets bear some uncertainties and risks which can be hedged against by resource reservation. In this work we analyze the use of real options traded at an additional contract market, to efficiently manage economical issues arising from the realization of a flexible resource reservation scheme. We derive the necessary conditions that even risk neutral agents have incentives to participate in such a market, as it increases their expected utility.","PeriodicalId":211759,"journal":{"name":"2009 42nd Hawaii International Conference on System Sciences","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115059159","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}

The question for this paper is whether distributed, offshored teams can consistently achieve the same level of performance. In particular, can a team establish a localized velocity and quality and then maintain or increase that velocity and quality when distributing teams across continents. Since 2006, Xebia (Netherlands) started localized projects with half Dutch and half Indian team members. After establishing localized hyperproductivity, they move the Indian members of the team to India and show the same velocity with fully distributed teams. After running XP engineering practices inside many distributed Scrum projects, Xebia has systematically productized a model for high performance, distributed, offshore teams with one of the lowest defect rates in the industry.","PeriodicalId":211759,"journal":{"name":"2009 42nd Hawaii International Conference on System Sciences","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116943896","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}

Structural equation modeling is applied to conceptualize and test the model. This model uses latent and observable variables and the application tests the hypothesis that technology use can be accounted for in a multidimensional model composed of four factors: Government Support/Legal Framework/Openness, Investment in Business and Technology, Socioeconomic Level, and Technology Utilization. Findings indicate a critical pathway of influences between the factors of government support/legal framework/openness, socio-economic level, and technology utilization. The results are important because they model complex path relationships between factors identified in the literature, but not previously available for SEM analysis. The paper suggests policy steps for national governments of developed and developing nations especially for policies stressing investment in ICT, strengthening of R and D, societal openness, a strong legal system, prioritization of ICT, and betterment of education.","PeriodicalId":211759,"journal":{"name":"2009 42nd Hawaii International Conference on System Sciences","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117008002","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}

This work contributes to outsourcing research by investigating the role of relational governance and its drivers for achieving more successful outsourcing relationships. We focus on the impact of a particular contextual variable which describes the importance of the outsourcing deal to the vendor, thereby turning the traditional perspective of resource dependency theory on outsourcing upside down. Using a case study approach, we show the significance of the importance of a deal between an IT outsourcing provider and its client to both the relationship quality and overall outsourcing success. Clients whose relative deal sizes are large compared to the provider's portfolio or who offer a strategic advantage to the provider are more likely to receive sound service quality and have a better IT outsourcing relationship.","PeriodicalId":211759,"journal":{"name":"2009 42nd Hawaii International Conference on System Sciences","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116015520","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}

The big success of established services like Facebook, Twitter or YouTube accelerates the transformation of the whole web. Next generation services are characterized by strong social interaction and collaboration tools. Significantly affected by this movement, conventional commerce platforms and online shops are gradually substituted by social shopping communities. Social commerce allows consumers to collaborate online, to exchange information about products and to get advice from trusted individuals. This paper introduces a scalable social software service model for an online shopping community built under consideration of existing best practice services. The model combines features of social networking, online shopping and social commerce sites. We present comparative analyses of these three service categories, significant showcases as well as the creation process of the model itself. The designed framework serves as basis for both service developers and researchers.","PeriodicalId":211759,"journal":{"name":"2009 42nd Hawaii International Conference on System Sciences","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123471597","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}

To this aim we surveyed the retail advisory operations of Germany's largest banks. We find that standardization enhances efficiency, quality and control of the advisory process. Additionally, IT intensity on its own shows positive effects on efficiency and quality as well, while it leads to more customer facing time needed for a single customer. Also, the interaction effect with process standardization is relevant. We conclude that IT creates business value through facilitating process standardization and process control. Our results strongly indicate that managers have to look carefully at the type of the processes before standardizing it.","PeriodicalId":211759,"journal":{"name":"2009 42nd Hawaii International Conference on System Sciences","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128626136","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}
