Usability and database search at the Swedish Employment Service

In this paper we report on a large-scale developmental project (AIS-95, 12,000 users) at the Swedish Labor Market Administration. The project is analyzed from the point of view of achieving good effective productivity in the final work system. Developmental projects of large size pose special problems in this respect. The aim of the project was to replace the current database application system (AF-90, 8000 users) with an improved system. As a background, we first analyzed the problems the employees have when using the current system (AF-90) from the perspectives of functionality, usability and information needs. No systematic attempt was made in the development project to integrate knowledge about users' problems with the AF-90 project into the AIS-95 project. Furthermore, different forms of user participation were tried in the project but still many users reported feeling a lack of influence on the project. Conclusions are given with respect to how some of the deficiencies found in the present project might be avoided in future large-scale projects.

Needs’ elaboration between users,designers and project leaders: Analysis of a design process of a virtual reality-based software

ContextThe participation of users in the design process is recognized as a positive and a necessary element as artifacts suit their needs. Two complementary approaches of users’ involvement co-exist: the user-centered design and the participatory design. These approaches involve learning process from users to designers and vice versa. However, there has no research in design of virtual reality (VR)-based software dealing with how the elaboration of needs is actually distributed in time and among users, designers and project leaders, as well as how it is actually supported by tools and methods.ObjectiveThis paper aims to observe, in a real design project of a virtual reality-based software, how the various stakeholders (users, designers, project leaders) actually participate by sharing and pulling pieces of information from the process of needs elaboration, and how these contributions evolve throughout the decisions made in the course of the project.MethodOur method, based on the observation of the practices in collective design, allows us to collect and analyze the relationship between each possible action (e.g., elicitation), each stakeholder who initiates these actions (e.g., users) and each phase of the design process (e.g., evaluation phase), and the dynamics of the construction of needs.ResultsOur results detail how the elicited needs are dealt with by designers, users and/or project leaders: (1) we show a strong contribution of users in the design, compared to others stakeholders, (2) among the needs elicited by users, most have been validated by the designers, (3) some elicited needs could have been firstly rejected and finally validated and implemented.ConclusionWe identify the reasons which justify and explain our results confronting them to the literature. We underline the conditions have been satisfied in our study in order to involve effectively users in the design of emerging technologies.     

一种改进项目多属性类别划分的推荐算法

针对传统度量相似性方法中忽略项目多属性类别差异的问题,提出一种改进项目多属性类别划分的推荐算法,首先构建项目—用户隶属矩阵挖掘用户间的隶属关系,并创建相似邻居FP-Tree以提取最近邻居集;然后分析用户间共同项目相似性和项目多属性类别划分的差异性,通过权重因子将共同项目和多属性类别融合,构建CNB度量模型度量邻居相似程度;最后对所得相似用户进行降序排列,获取更加精准的相似用户,完成推荐工作。结合医药数据集验证该算法的有效性,结果表明其时间复杂度、推荐准确性和平均精度均值均有较好的提升。     

User commitment and collaboration: Motivational antecedents and project performance

ContextPrior research into the success of information system development projects views user commitment and collaboration as unrelated concepts in models that take either a perspective of mediators or one of processes. This perspective is limiting in that mediators and processes may interact during the course of an information system development project.ObjectiveIn this work, we model both mediators and processes as important to project outcomes and propose that processes will also be impacted by affective mediators, specifically the behavioral mediator of user commitment and the project process of collaboration. The model also allows behavioral antecedents to be considered in relation to the mediation variable, specifically the ability of the users and the extrinsic motivators perceived by the users.MethodA questionnaire containing constructs of collaboration processes, user commitment, abilities, and extrinsic motivation are completed by users in a development project and project success is measured by the IS staff for a matching independent variable. 128 matching pairs were collected and the model analyzed using partial least squares regression.ResultsResults indicate that the affective mediator can be influenced by the tested antecedents showing that IS project managers should be able to choose users with essential abilities and also establish sufficient rewards to employees, even those who may not be direct subordinates. Similarly, collaboration is still important to the success of a project, indicating that procedures to encourage collaboration be installed from the beginning of the project. However, commitment alone is sufficient to predict collaboration, meaning that motivation outside the processes in place may not be necessary to encourage collaboration between the users and IS staff.ConclusionIS researchers should consider both process mediators and affective states in future work when considering the link between antecedent inputs of software projects to the success of outputs. IS managers should promote commitment among users beyond placing collaboration mechanisms in place. This might require project managers have more decision authority in the rewards provided to user participants.     

Wearing two hats: analyst-managers for small software projects

With the evolution of software development, companies have changed their project methodology and are asking IT employees to evolve with them. The business analyst talks to users, ironing out the details of what they wanted and balancing that wish list against what an IT system could economically or practically deliver. The business analyst also ensures that users develop business processes to support the software. The actual task of writing the software falls to a project manager and his team of software developers. Today, companies commonly ask IT managers to assume the business analyst role in addition to their duties as project manager, especially in small projects. This article discusses how IT managers can successfully navigate the thin line between business analyst and project manager.     

Making the Internet accessible for people with cognitive and communication Impairments

This paper provides an overview of the work of the European Union (EU) World Wide Augmentative and Alternative Communication (WWAAC) project, which aims to make the electronic highway more accessible to people with cognitive and communication impairments, in particular those persons using symbols instead of text to communicate. Many of these users will also be users of alternative and augmentative communication (AAC) devices. The appropriateness of guidelines from the World Wide Web Consortium (W3C) are discussed, with the finding that few specific guidelines are available to make Web sites truly accessible and usable for these user groups. We propose that additional guidelines are required in order to facilitate access to Web pages for AAC users. Requirements capture and preliminary evaluation activities within the project have led to the development of draft guidelines that will be refined and validated as the project reaches its final evaluation phase. These draft guidelines are discussed along with other developments needed in this area.     

The relative influence of management control and user–IS personnel interaction on project performance

Research has failed to establish a conclusive link between levels of user involvement and information system project success. Communication and control theories indicate that the quality of interactions between users and inofrmation personnel may serve to better the coordinaton in a project and lead to greater success. A model is developed that directly relates management control to the quality of interaction and project success, with interaction quality as a potential intermediary. These variables provide a more distinct relationship to success as interactions are more structurally defined and controlled. A survey of 196 IS professionals provides evidence that management control techniques improve the quality of user–IS personnel interactions and eventual project success. These formal structures provide guidelines for managers in controlling the critical relations between users and IS personnel.
