What influences the speed of prototyping? An empirical investigation of twenty software startups

It is essential for startups to quickly experiment business ideas by building tangible prototypes and collecting user feedback on them. As prototyping is an inevitable part of learning for early stage software startups, how fast startups can learn depends on how fast they can prototype. Despite of the importance, there is a lack of research about prototyping in software startups. In this study, we aimed at understanding what are factors influencing different types of prototyping activities. We conducted a multiple case study on twenty European software startups. The results are two folds, firstly we propose a prototype-centric learning model in early stage software startups. Secondly, we identify factors occur as barriers but also facilitators for prototyping in early stage software startups. The factors are grouped into (1) artifacts, (2) team competence, (3) collaboration, (4) customer and (5) process dimensions. To speed up a startups progress at the early stage, it is important to incorporate the learning objective into a well-defined collaborative approach of prototypingComment: This is the author's version of the work.

Teachers' adoption of inquiry-based learning activities : the importance of beliefs about education, the self, and the context

Even though studies have shown that the impact of professional development on inquiry-based learning (IBL) tends to remain limited when it fails to consider teachers' beliefs, there is little known about how these beliefs influence teachers' adoption of IBL. In answer to this issue, the present study offers a framework that explains teachers' use of IBL through three constitutive dimensions of beliefs systems, covering the constructs of education, the self, and the context. This framework is empirically investigated through a survey study with 536 secondary school history teachers. The resulting data are used to estimate a structural equation model (SEM), which indicates that the framework is able to explain a relatively large portion (38%) of the variance in teachers' decision to implement IBL. Based on the findings, the implications for professional development and research on teachers' use of IBL in general, and within history education in particular, are discussed

Report of the user requirements and web based access for eResearch workshops

The User Requirements and Web Based Access for eResearch Workshop, organized jointly by NeSC and NCeSS, was held on 19 May 2006. The aim was to identify lessons learned from e-Science projects that would contribute to our capacity to make Grid infrastructures and tools usable and accessible for diverse user communities. Its focus was on providing an opportunity for a pragmatic discussion between e-Science end users and tool builders in order to understand usability challenges, technological options, community-specific content and needs, and methodologies for design and development. We invited members of six UK e-Science projects and one US project, trying as far as possible to pair a user and developer from each project in order to discuss their contrasting perspectives and experiences. Three breakout group sessions covered the topics of user-developer relations, commodification, and functionality. There was also extensive post-meeting discussion, summarized here. Additional information on the workshop, including the agenda, participant list, and talk slides, can be found online at http://www.nesc.ac.uk/esi/events/685/ Reference: NeSC report UKeS-2006-07 available from http://www.nesc.ac.uk/technical_papers/UKeS-2006-07.pd

Owner challenges on major projects: The case of UK government

Many studies agree that owner organisations are important for successful project organising, but they tend to focus on particular aspects of project organising rather than providing a holistic analysis of owners as organisations. Our objective is to collect evidence of the full range of challenges public sector owners face in managing their major projects. After reviewing the literature on owner organisations, we carry out a case survey of 26 major projects to identify the principal challenges using a content analysis of UK National Audit Office Value for Money reports. Our original contribution is that the findings provide the first comprehensive picture of the full range of challenges of project organising faced by owner organisations. These findings push us theoretically to extend the scope of research in project organising to identify an extended core set of dynamic capabilities for project owner organisations to address these challenges

Knowledge management in the voluntary sector: A focus on sharing project know-how and expertise

Voluntary sector organisations are operated principally by volunteers who are not obliged to share their knowledge, as might be expected in a for profit company, with a greater consequent loss of knowledge should individuals leave. This research examines how a volunteer-led organisation, the Campaign for Real Ale (CAMRA), acquires, stores and shares its project knowledge in the context of event management. Three annual CAMRA festivals of different sizes and maturity were selected to see how volunteers' knowledge is managed in the process of organising their festivals. Key festival officers were interviewed and focus groups, comprising of festival volunteers, were conducted. While the maturity of a festival and its size seemed to influence the ways in which knowledge was managed there were some commonalities between festivals. Evident was a strong master-apprentice model of learning with little formal training or record keeping except, that is, where legislation and accountability in treasury and health and safety functions were necessary. Trust between volunteers and their need to know and to share information appeared to be dependent, in part, on their perception and confidence in the success of the overarching project organisation, and this helped shape volunteers' knowledge sharing practices. Whilst there was evidence of a laissez-faire approach to codification and the sharing of knowledge, this was less so when volunteers recognised a genuine lack of knowledge which would hinder the success of their festival. The analysis also highlighted factors related to the sharing of knowledge that, it is suggested, have not been identified in the for-profit sector

Back to practice, a decade of research in E-government

E-government is a multidisciplinary field of research based initially on empirical insights from practice. Efforts to theoretically found the field have opened perspectives from multiple research domains. The goal of this chapter is to review evolution of the e-government field from an institutional and an academic point of view. Our position is that e-government is an emergent multidisciplinary field of research in which focus on practice is a prominent characteristic. Each chapter of the book is then briefly presented and is positioned according to a vision of the e-government domain of research.E-government, Case study, E-administration, Public domain

Supporting Defect Causal Analysis in Practice with Cross-Company Data on Causes of Requirements Engineering Problems

[Context] Defect Causal Analysis (DCA) represents an efficient practice to improve software processes. While knowledge on cause-effect relations is helpful to support DCA, collecting cause-effect data may require significant effort and time. [Goal] We propose and evaluate a new DCA approach that uses cross-company data to support the practical application of DCA. [Method] We collected cross-company data on causes of requirements engineering problems from 74 Brazilian organizations and built a Bayesian network. Our DCA approach uses the diagnostic inference of the Bayesian network to support DCA sessions. We evaluated our approach by applying a model for technology transfer to industry and conducted three consecutive evaluations: (i) in academia, (ii) with industry representatives of the Fraunhofer Project Center at UFBA, and (iii) in an industrial case study at the Brazilian National Development Bank (BNDES). [Results] We received positive feedback in all three evaluations and the cross-company data was considered helpful for determining main causes. [Conclusions] Our results strengthen our confidence in that supporting DCA with cross-company data is promising and should be further investigated.Comment: 10 pages, 8 figures, accepted for the 39th International Conference on Software Engineering (ICSE'17

Profiling Corruption Perception in Africa: the Role of Religion, Gender, Education and Age

This study investigates attitude towards corruption and the role of gender, religion, education and age using a Nigerian survey data. It also seeks to establish how attitudes towards corruption relates to some other reported ethical measures such as Islamic work ethics, money ethic and corruption perception. Over 3800 questionnaires were administered with 1833 or about 48% response rate. Results revealed no significant gender differences in corruption but women reported being more religious. Also Christians rated the incidence of corruption as higher than Muslims although the sample size skews significantly in favour of the former. Older and more educated people also rated corruption incidence higher
