This paper describes a pilot study using a WWW-based Group Support System (GSS) to facilitate students learning Soft Systems Methodology (SSM). The students were each given fictitious stakeholder roles to play in a hypothetical, but realistic situation. The instructors acted as the facilitators of the process. The students were asked to represent the interests of their fictitious role. The use of the GSS allowed them to remain anonymous to the other students, while still interacting at a deep level. Students discussed each other's perspectives, raised issues, and created and discussed SSM products, including rich pictures, root definitions, and conceptual models. The students were surveyed afterwards and also wrote papers critiquing their experience. This paper describes the process used, the results obtained from the student surveys and reports, as well as the instructors' experiences and impressions. We further describe planned future research, including discussion of the possibility of using this method to support distance education.
Soft Systems Methodology is a general method for investigating and learning about a problem situation, then taking suitable action to improve on the situation. SSM is useful in situations with conflict among stakeholders or where the goals of a system are uncertain and/or debatable. Generally, the person applying SSM guides the problem stakeholders to use the SSM techniques themselves, so that they determine and implement their own solutions. A SSM practitioner must teach SSM concepts to the stakeholders.
GSS can be defined as "interactive computer-based environments which support concerted and coordinated team effort toward completion of joint tasks" (Nunamaker et al, 1996). GSS commonly support meetings and group decision making using tools for brainstorming, ranking, voting, and/or structuring discussions (posting messages/assertions and attaching comments to messages, comments to comments, etc). Teaching and learning are also common group activities that GSS can support. GSS have been proposed as a way to facilitate the group processes in SSM (Galliers et al, 1991, Travis et al, 1996), including in situations where the stakeholders are too widely distributed to meet face to face (Venable and Travis, 1996a, b). A large part of the difficulty in applying SSM to a distributed group of stakeholders via a distributed GSS is in conveying the SSM concepts in essentially a distance-learning situation.
The author recently ran a pilot study researching the use of a to support the distributed application of SSM (Venable and Travis, 1998b). The pilot study involved 46 third year students/participants, presenting a good opportunity to investigate additional questions about the usefulness of a GSS to enhance teaching and learning about both SSM and GSS.

As an assignment for a 3rd year IS project unit, the students were required to participate in the study and then to write two reports afterwards: a summary of the findings of the fictional SSM investigation and a critique of the study. The participants were surveyed before and afterwards, to get a baseline on their demographics and prior experience with SSM and GSS, as well as to get quantitative data about their subjective ratings of their experiences.
The WAFIS home page introduced the project and described how the fictional study would be conducted (Venable and Travis, 1998a). The home page contained links to other pages about forests and to a page that informed the participants about what the current activity was. The home page also linked to web pages explaining SSM, including the various stages and techniques involved (Travis and Venable, 1998). Finally, the home page linked to DiscussionWeb.
DiscussionWeb provides facilities for structured discussion, brainstorming, ranking, and voting. It is relatively simple and easy to learn using a built-in tutorial. Anyone with a web browser can use it. We organised the discussions and posted informative messages to DiscussionWeb where all participants had easy access to them.
The planned process was to guide the participants through the first four stages of SSM and to get them to use the different SSM techniques, using the web pages as a guide. Each participant could ask questions at any time via DiscussionWeb. All of the participants could then read the answers. The planned activities included raising issues and using SSM techniques, including rich pictures, CATWOE, root definitions, and conceptual models. Participants drew rich pictures and conceptual models using a drawing package or PowerPoint or by hand-drawing and scanning the drawing. Each contribution was then uploaded, linked, and discussed via DiscussionWeb. We also planned to use the decision support tools (ranking and voting) to try to reach consensus on a single root definition and conceptual model.
In this way, the students would all get first hand experience using the SSM techniques, seeing how others used the techniques, and discussing and critiquing how they were used. Additionally, they would see how stakeholders perceived the situation differently, and how GSS might be used to help address the difficulties in reaching agreement. Finally, they (and we, the researchers) would see how a web-based GSS might be used to support SSM where the stakeholders could not see each other face to face.
There was a substantial level of participation, as evidenced from the statistics given below:
|Learned a lot about SSM
Learned a lot about GSS
Learned by reading SSM pages
Learned by creating and posting
Learned from others' contributions
Learned from others' comments
Learned by writing outcome summary
Learned by writing critical report
Fictional role playing is a good way to learn
Fun creating rich picture
Fun to play my fictional role
Enjoyed reading others' perspectives
Many comments were also positive, noting things like how the experience was enjoyable and a nice break from other ways of learning. We also received many useful suggestions for improvements and reports of problems.
Our immediate plans are to make some improvements to the facilities and to run another study while teaching SSM. Once we are satisfied with the results, we hope to try it out for distance education and real application of SSM with distributed stakeholders.
