Karunakaran, Arvind and Purao, Sandeep (2011): Templating in practice. In: Proceedings of the 2011 iConference 2011. pp. 694-696. Available online
'Templates' are pervasive within all the spheres of organizations. They are considered to represent, among other things, rules, routines and best practices accumulated from the past. Despite their ubiquity within many organizations, little is known about these templates. Through this research-in-progress study, we try to investigate why and how these templates are created, how they are used and appropriated in practice, and how they become intrinsic to everyday organizing. We use the term "templating" to elaborate upon the sociomaterial dynamics that underpin the creation, categorization, use/non-use, and appropriation of templates. Initial results suggest that templates may be more than mere records of 'procedural know-hows' within the organization. They may represent a materiality that is enmeshed in the fabric of organizational practices, often inseparable from the conditions of their creation and use. From the gained descriptive insights, we are in the process of developing a platform called ReKon that is composed of 'fine-grain project template chunks' which facilitates user-led recombinations.

Evaluating collaborative systems remains a significant challenge. Most evaluation methods approach the problem from one of two extremes: focused evaluation of specific system features, or broad ethnographic investigations of system use in context. In this paper, we develop and demonstrate a middle ground for evaluation: explicit reflections on scenarios of system use coupled with analysis of the consequences of these use scenarios, represented as claims. Extending prior work in scenario-based design and claims analysis, we develop a framework for a multi-perspective, multi-level evaluation of collaborative systems called SWIMs: scenario walkthrough and inspection methods. This approach is centered on the capture, aggregation, and analysis of users' reflections on system support for specific scenarios. We argue that this approach not only provides the contextual sensitivity and use centricity of ethnographic techniques, but also sufficient structure for method replication, which is common to more feature-based evaluation techniques. We demonstrate with an extensive field study how SWIMs can be used for summative assessment of system performance and organizational contributions, and formative assessment to guide system and feature re-design. Results from the field study provide preliminary indications of the method's effectiveness and suggest directions for future research.

We report on the use of scenario-based methods for evaluating collaborative systems. We describe the method, the case study where it was applied, and provide results of its efficacy in the field. The results suggest that scenario-based evaluation is effective in helping to focus evaluation efforts and in identifying the range of technical, human, organizational and other contextual factors that impact system success. The method also helps identify specific actions, for example, prescriptions for design to enhance system effectiveness. However, we found the method somewhat less useful for identifying the measurable benefits gained from a CSCW implementation, which was one of our primary goals. We discuss challenges faced applying the technique, suggest recommendations for future research, and point to implications for practice.
