Abstract. This paper describes an online co-creation study done via an online co-creation platform Owela as well as shares industrial experiences and lessons learnt about the study. The Owela study was conducted in order to provide a deeper  understanding of users’ perceptions of cloud services and their security. By utilising  the online co-creation platform it was possible to get quick and easy contact to  geographically distributed cloud service users. For the company Owela offered an  efficient way to apply online user participation while for the end users Owela enabled  convenient participation in various co-creation activities regardless of time and place.  As an end result of the study the voice of the cloud service users was turned into  several new business ideas.

Abstract— How do organizations know they are designing products and services that  their customers will value? This paper describes the initial results of the first four  stages of a methodology for integrating customer Values in Experience design (ViEx).  The theory of universal value structure was adapted to examine customer  values in two contexts: online interaction (N=725) and shopping experience (N=742).  The principle component analysis was used to identify the values structure in each  context. The components represented persona dimensions and their relative order of  importance characterized individual customers. The commonalities of the persona  dimensions preferences were analyzed and customers were grouped by dimension  preferences. Finally, the valuesbased persona descriptions were developed and  complemented with demographic data and information from context-specific questions. The paper concludes with application of methodology to differentiation  strategies in highly competitive business environments such as the cloud. The  research also contributes to the discussion of values in context.

Article: User Experience Design Goes Agile in Lean Transformation - A Case Study

Published by: AriTurunen Last modified: 2012.09.17

This paper describes the results of a single-case case study, exploring the role of user experience (UX) work in agile software development. The case study company is a large multinational telecommunication company undergoing a lean transformation process. In this case, lean transformation includes the adoption of agile software development practices. Transformation to agile practices had taken place one year prior to the analysis. The analysis is based on documentation analysis and semi-structured interviews of seven software development professionals. The results show that there were difficulties integrating UX design and software engineering work in an agile and iterative manner. The transition process succeeded in shifting UX and related documentation to a central planning role. The roles of the UX designers in the teams were still under re-definition. There was also a clear need to establish new ways of collaboration between UX professionals and software designers.

Abstract
Compared to desktop devices, mobile devices have inherent constraints such as  limited processing power, memory, and battery capacity. With the proliferation of  resource-hungry applications, researchers are looking for new solutions to address  these limitations. One such solution is mobile cloud computing (MCC), which uses  cloud infrastructure to enhance the capabilities of mobile devices. This paper focuses  on a related, emerging technology called mobile computation offloading (MCO),  where the emphasis is on dynamically offloading computation from native applications running on mobile devices to outside surrogates such as cloud infrastructure. We use  an exploratory approach to evaluate the business potential of MCO by identifying  critical factors that influence the technology evolution of MCO. We base this  evaluation on a literature review of MCO and utilize a research framework derived  from the existing literature on technology evolution and MCO.

Abstract—Cloud computing improves utilization and flexibility of allocating computing  resources while reducing the infrastructural costs. However, cloud technology is still  proprietary in many cases and is tainted by security issues rooted in the multi-tenant  environment of the cloud. For instance, the virtual machines of two competing  companies could be served by the same underlying host machine in an Infrastructure  as a Service (IaaS) type of cloud and this represents a security threat  to be addressed. As a solution to this multi-tenancy problem, the Host Identity  Protocol (HIP) offers a standardized way to authenticate and protect data flows  between tenants belonging to the same security domain. In this paper, we have  experimented with HIP in order to address the multi-tenant challenges for public and  hybrid IaaS clouds. In our design, developers and administrators can access cloud  services directly over HIP, whereas consumers access the cloud without HIP using a  reverse HTTP proxy. The proxy also acts as a load balancer for a distributed test  service deployed both in an EC2 public cloud and a private cloud. The performance of  the system offers efficiency comparable to SSL and essentially utilizes the same  cryptographic algorithms with similar processing costs. Consequently, this implies that the proposed scheme is a viable alternative to mitigate some of the privacy issues  related to multi-tenancy within a single data center and to secure communications  between two clouds in the case of a hybrid cloud.
