FlexSIG-Flexible software inspection groupware

The objective of this research is to design and build a groupware system which will allow members of a distributed group more flexibility in performing software inspection. Software inspection, which is part of non-execution based testing in software development, is a group activity. The groupware system aims to provide a system that will improve acceptability of groupware and improve software quality by providing a software inspection tool that is flexible and adaptable. The groupware system provide a flexible structure for software inspection meetings. The groupware system will extend the structure of the software inspection meeting itself, allowing software inspection meetings to use all four quadrant of the space-time matrix: face-to-face, distributed synchronous, distributed asynchronous, and same place-different time. This will open up new working possibilities. The flexibility and adaptability of the system allows work to switch rapidly between synchronous and asynchronous interaction. A model for a flexible groupware system was developed. The model was developed based on review of the literature and questionnaires. A prototype based on the model was built using java and WWW technology. To test the effectiveness of the system, an evaluation was conducted. Questionnaires was used to gather response from the users. The evaluations ascertained that the model developed is flexible and adaptable to the different working modes, and the system is capable of supporting several different models of the software inspection process.

Categorically speaking:reflecting AEC/FM participants' requirements in Groupware

Groupware allows participants in an AEC/FM project to timely share relevant electronic project information at near real-time speed. One challenge of existing groupware tools is the varying information categorization needs of different AEC/FM project participants within the same groupware environment. This paper introduces initial results of a survey of several AEC/FM companies' project information categorizations. These initial results reveal differences in the ways AEC/FM project participants organize project information within each company. These differences will result in the need for a comprehensive information categorization solution when companies move their organized company specific project information to a project-wide repository in groupware. In the future, as a result of this research, a comprehensive project categorization scheme will be introduced which would allow participant-specific views of the AEC/FM project information to be rendered.

Integrating security services into computer supported cooperative work

This research describes the development of a groupware system which adds security services to a Computer Supported Cooperative Work system operating over the Internet. The security services use cryptographic techniques to provide a secure access control service and an information protection service. These security services are implemented as a protection layer for the groupware system. These layers are called External Security Layer (ESL) and Internal Security Layer (ISL) respectively. The security services are sufficiently flexible to allow the groupware system to operate in both synchronous and asynchronous modes. The groupware system developed - known as Secure Software Inspection Groupware (SecureSIG) - provides security for a distributed group performing software inspection. SecureSIG extends previous work on developing flexible software inspection groupware (FlexSIG) Sahibuddin, 1999). The SecureSIG model extends the FlexSIG model, and the prototype system was added to the FlexSIG prototype. The prototype was built by integrating existing software, communication and cryptography tools and technology. Java Cryptography Extension (JCE) and Internet technology were used to build the prototype. To test the suitability and transparency of the system, an evaluation was conducted. A questionnaire was used to assess user acceptability.

Assessing the motivation of MDs to use computer-based support at the point-of-care in the emergency department

A significant body of research investigates the acceptance of computer-based support (including devices and applications ranging from e-mail to specialized clinical systems, like PACS) among clinicians. Much of this research has focused on measuring the usability of systems using characteristics related to the clarity of interactions and ease of use. We propose that an important attribute of any clinical computer-based support tool is the intrinsic motivation of the end-user (i.e. a clinician) to use the system in practice. In this paper we present the results of a study that investigated factors motivating medical doctors (MDs) to use computer-based support. Our results demonstrate that MDs value computer-based support, find it useful and easy to use, however, uptake is hindered by perceived incompetence, and pressure and tension associated with using technology.
