OpenProposal: Towards Collaborative End-User Participation in Requirements Management By Usage of Visual Requirement Specifications
15th IEEE International Requirements Engineering Conference (RE 2007), 2007Co-Authors: Asarnusch RashidAbstract:Even though end-User Participation in requirements engineering (RE) is important, it is not frequently used at present. Reasons can be found in the large expenditure of time for organizing and carrying out surveys as well as in the time it takes to understand the Users' requirements. This research is supposed to contribute to this problem by presenting the OpenProposal approach for distributed User Participation using visual requirement specifications and outlining the research agenda for developing and evaluating methods and tools for collaborative endUser Participation in Requirements Management.

visual requirement specification in end User Participation
2006 First International Workshop on Multimedia Requirements Engineering (MERE'06 - RE'06 Workshop), 2006Co-Authors: Asarnusch Rashid, David Meder, Jan Wiesenberger, Astrid BehmAbstract:End-User Participation in requirements engineering (RE) is important, but not frequently used at the moment. Reasons are the large expenditure of time for organizing and carrying out surveys as well as the time it takes to understand the Users? requirements and to formulate them textually. But even textually formulated requirements are not sufficient, as Users are no experts, do not have enough time beside their job to model complex requirements and describe their requirements properly. It is therefore necessary to formulate the requirements visually. Actual methods are too complex and inefficient, because they need training and can?t be integrated into the day-to-day business of end-Users. Thus, Users should be able to annotate their ideas directly on their screen and submit them to a web based collaboration platform. The main goal is to obtain complete requirements and, simultaneously, to save the time of all stakeholders in the whole development process.

User Participation in urban green spaces for the people or the parks
Urban Forestry & Urban Greening, 2015Co-Authors: Hanna Fors, Julie Froik Molin, Melissa Anna Murphy, Cecil Konijnendijk C Van Den BoschAbstract:The provision and administration of high quality urban public green spaces intertwines issues of planning, design, management and maintenance with governance. The benefits of such spaces are often tied to social justice, public health and recreation, biodiversity and helping cities to deal with climate change. International policies and changes in public administration have encouraged User Participation across multiple phases of green space development. Although sceptics towards Participation are easily found supporting arguments sometimes stand without critique, not questioning how Participation affects the physical quality of green spaces. This literature review surveyed empirical scientific studies seeking to answer the following research question: How does research to date reflect over User Participation's contribution to public urban green space quality? The review includes 31 articles from peer-reviewed scientific journals and finds an array of arguments used to support and attribute potential benefits to Participation. However, analysing what has been empirically tested in these articles shows an even and general lack of proof for these arguments, implying that many arguments for Participation are taken for granted. A particularly large disparity was found between the discussing and testing of many arguments regarding how Participation may directly benefit urban green spaces. Rather than assessing the physical outputs of Participation, most of the empirical studies tested process benefits to Users and administrators. Due to the discovered predominance of these process-driven studies, it remains unclear whether Participation actually improves green spaces, or if it is just for the benefit of the people involved. The gap in scientific knowledge found here calls for a re-focus to case level research, empirically testing where the actual benefits of Participation lie and how Participation processes might best lead to high quality green spaces in practice.

User Participation in information systems security risk management
MIS Quarterly, 2010Co-Authors: Janine L Spears, Henri BarkiAbstract:This paper examines User Participation in information systems security risk management and its influence in the context of regulatory compliance via a multi-method study at the organizational level. First, eleven informants across five organizations were interviewed to gain an understanding of the types of activities and security controls in which Users participated as part of Sarbanes-Oxley compliance, along with associated outcomes. A research model was developed based on the findings of the qualitative study and extant User Participation theories in the systems development literature. Analysis of the data collected in a questionnaire survey of 228 members of ISACA, a professional association specialized in information technology governance, audit, and security, supported the research model. The findings of the two studies converged and indicated that User Participation contributed to improved security control performance through greater awareness, greater alignment between IS security risk management and the business environment, and improved control development. While the IS security literature often portrays Users as the weak link in security, the current study suggests that Users may be an important resource to IS security by providing needed business knowledge that contributes to more effective security measures. User Participation is also a means to engage Users in protecting sensitive information in their business processes.

linking it implementation and acceptance via the construct of psychological ownership of information technology
Journal of Information Technology, 2008Co-Authors: Henri Barki, Guy Pare, Claude SicotteAbstract:The present paper proposes psychological ownership of IT (POIT) as a construct that can provide a much needed linkage between the IT implementation and IT acceptance research streams. To assess this idea, a research model was developed where POIT was hypothesized to mediate the influence of User Participation on perceived usefulness (PU) and perceived ease of use (PEOU). This model was tested with questionnaire data collected from 91 physicians who were using a newly implemented clinical information system across a network of medical clinics. The results of partial least square analysis of the data indicated that POIT was a significant mediator of the influence of User Participation on PU and PEOU, providing strong support for the research model.

Communication as a dimension of User Participation
IEEE Transactions on Professional Communication, 2001Co-Authors: Jon Hartwick, Henri BarkiAbstract:User Participation is defined as the extent to which Users or their representatives carry out assignments and perform various activities and behaviors during the system development process. This work has identified three dimensions of User Participation: responsibility, the User-IS (information system) relationship and hands-on activity. However, this 3D view of User Participation does not capture an important aspect of Participation: the communication between Users and with various stakeholders. This paper replicates and extends past research by proposing the addition of a fourth dimension: communication activity. Data collected from 324 Users drawn from 162 IS development teams were used to replicate our three dimensions and to examine evidence for the construct validity of the new dimension. Consistent with expectations, strong evidence was found suggesting that communication activity needs to be considered as a fourth dimension of User Participation.

Measuring User Participation, User involvement, and User attitude
MIS Quarterly, 1994Co-Authors: Henri Barki, Jon HartwickAbstract:Defining User Participation as the activities performed by Users during systems development, User involvement as the importance and personal relevance of a system to its User, and User attitude as the affective evaluation of a system by the User, this study aims to: (1) develop separate measures of User Participation, User involvement, and User attitude, (2) identify key dimensions of each construct, and (3) investigate the relationships among them. Responses from Users in organizations developing new information systems were used to create an overall scale measuring User Participation (along with three subscales reflecting the dimensions of responsibility, User-IS relationship, and hands-on activities), an overall scale measuring User involvement (along with two subscales reflecting the dimensions of importance and personal relevance), and a scale measuring User attitude. Analysis of the data provides evidence for the reliability and validity of the three constructs and their dimensions. User Participation has long been considered a key variable in the successful development of information systems. However, past research has failed to clearly demonstrate its benefits. The measures developed in this study provide a useful starting point for deciphering the precise nature of the relationship among User Participation, involvement, and attitude during systems implementation.

Explaining the Role of User Participation in Information System Use
Management Science, 1994Co-Authors: Jon Hartwick, Henri BarkiAbstract:Even though User Participation in information system development has long been considered to be a critical factor in achieving system success, research has failed to clearly demonstrate its benefits. This paper proposes User involvement as an intervening variable between User Participation and system use. Embedding the constructs of Participation and involvement into the theoretical framework of Fishbein and Ajzen, a model is developed and tested in a field study of information system projects. Several key findings emerge from the study. User Participation and User involvement represent two distinct constructs, with Participation leading to involvement, and involvement mediating the relationship between Participation and system use. The critical dimension of User Participation is overall responsibility. The role of User Participation and involvement is different, depending upon whether system use is mandatory or voluntary.

measuring the impact of User Participation in agricultural and natural resource management research
Agricultural Systems, 2003Co-Authors: Nancy L Johnson, Nina Lilja, Jacqueline Anne AshbyAbstract:Abstract Persistent poverty and environmental degradation demand a constant effort to improve the effectiveness and impact of agricultural and natural resource management research. Participatory research methods have developed as a way to help researchers better target their work towards the needs and constraints of specific stakeholder groups. Participatory research may also strengthen the capacity of participants to initiate a continuous process of innovation. The capacity of farmers and other end Users of technologies to innovate may be particularly important in poor, marginal environments where conditions are highly variable. This paper assesses the impact of using participatory methods in three agricultural research projects which have a natural resource management focus. Mixed methods are used to assess technological, economic, human, and social impacts and the cost implications of incorporating beneficiaries into the research process. User Participation was found to influence priorities and practices within and beyond the specific projects studied. Participation led to more relevant technologies and greater economic impacts, especially when Participation was early in the research process. Impacts on farmer capacity were high when farmers worked intensively with researchers over a period of time. Use of participatory methods changes research costs. When farmers took over tasks that were previously done by researchers, some of the research costs were transferred to farmers. When participatory methods were combined with conventional on-farm research, there were also start-up costs, because researchers and farmers needed to learn new research methods. However these additional one-time costs were not significant in terms of total research costs.

User Participation in watershed management and research
Water Policy, 2002Co-Authors: Nancy L Johnson, Helle Munk Ravnborg, Olaf Westermann, Kirsten ProbstAbstract:Abstract Many watershed development projects around the world have performed poorly because they failed to take into account the needs, constraints, and practices of local people. Participatory watershed management—in which Users help to define problems, set priorities, select technologies and policies, and monitor and evaluate impacts—is expected to improve performance. User Participation in watershed management raises new questions for watershed research, including how to design appropriate mechanisms for organizing stakeholders and facilitating collective action. Management of a complex system such as a watershed may also require User Participation in the research process itself.

User Participation in fisheries management lessons drawn from international experiences
Marine Policy, 1995Co-Authors: Svein Jentoft, Bonnie J. MccayAbstract:Abstract This paper summarizes the findings of two partly overlapping comparative international projects on government-industry interaction in fisheries management in the seven Nordic countries, the USA, Canada, Spain, France and New Zealand. Fisheries management agencies often rely on inputs from User groups in planning, implementation and enforcement of regulatory systems. User involvement in fisheries management is a controversial subject in most of the countries represented here. Too much or too little involvement seem equally problematic. The issue is not so much if and why User groups should be involved, as how, which is basically a political question. User Participation is a means through which Users are empowered, and there is always a possibility that some will win while others will lose or be left out entirely. However, the question of how User groups should be incorporated in the management process is also a question of institutional design. In this respect, great diversity is demonstrated in our case studies. This suggests that the question of how Users should be involved has many possible answers - none of them easy.
