Our submission to the NIER (New Ideas and Emerging Results) track at ICSE 2010 has been accepted!
In this paper, Peggy and I explore the idea that the use of tags in task management systems could lead to the introduction of new task categories. This research was prompted by the observation that the software development team in one of our Jazz case studies used tags such as linux and windows to indicate that a particular task was specific to an operating system. During the replication of our study a year later, we observed that the team didn’t use these tags anymore, instead the category Operating System had been made a field in every task.
Looking at this phenomenon in more detail, we found that there were other instances: Tags such as testing and selfhosting had been replaced by a How Found category, and tags such as eclipse, firefox and ie had been replaced by a Client category.
Based on these preliminary insights, we pose the following research questions:
RQ How can tagging play a role in bridging lightweight task management and heavyweight task management?
- What role do tags play in the adoption of new task categories?
- How can data on the use of tags help determine the right balance between lightweight and heavyweight task organization?
- How is software developers’ use of tags for task organization different from the tag use of users outside of software development?
We have focused on the first sub question for the NIER paper, but the positive comments from our reviewers encouraged us to keep working on this research. Looking beyond Jazz, a very interesting case is given by the way labels are implemented in Google Code (see: http://code.google.com/p/support/wiki/IssueTracker#Labels). Their concept of labels is similar to social tagging in other task management systems. However, the Google Code issue tracker goes beyond basic labels to support key-value labels. Key-value labels contain one or more dashes, and the part before the first dash is considered to be a field name while the part after that dash is considered to be the value. For each project, a list of predefined labels and their meaning can be specified. Studying how developers make use of this approach is on top of our to-do list.
This is the preliminary abstract of our NIER paper:
In collaborative software development projects, tasks are often used as a mechanism to coordinate and track shared development work. Modern development environments provide explicit support for task management where tasks are typically organized and managed through predefined categories. Although there have been many studies that analyze data available from task management systems, there has been relatively little work on the design of task management tools. In this paper we explore how tagging with freely assigned keywords provides developers with a lightweight mechanism to further categorize and annotate development tasks. We investigate how tags that are frequently used over a long period of time reveal the need for additional predefined categories of keywords in task management tool support. Finally, we suggest future work to explore how integrated lightweight tool features in a development environment may improve software development practices.
