“…This result is similar to recent results in software development [22,23] which also point out that there is a difference between the coordination efforts of professionals. This raises the question of how current tools for sysadmins should be designed: currently they are designed assuming that the collaborative effort of individuals is very similar, which is not the case.…”

In this paper we describe the results of an empirical study about the information needs of system administrators. This study is based on an electronic survey with more than 200 systems administrators, or sysadmins, working on incident management in a large scale IT service delivery organization. The survey covered their information needs in both complex and routine situations. The results of the survey described in this paper go beyond previous work on system administrators by presenting a much more complex picture, suggesting that sysadmins make low usage of knowledge management tools; largely adopt personal communication and collaboration tools; and finally, need to gather information about customers from a complex set of stakeholders. The system administrators also indicated in our survey that the most useful sources of information in handling complex incidents are: (i) the customer; (ii) the customer account team; and (iii) other employees who were experts both in the customer and in particular aspects of the delivery of services. This study indicates that knowledge management in IT service factories is very challenging and possibly should evolve from the often adopted passive model to a dynamic knowledge management style emphasizing both knowledge reusability through information technologies and knowledge sharing through informal discussions among employees.

“…Today, software development is influenced in myriad ways by how developers talk, and what they talk about. With distributed teams developing and maintaining many software systems today (Cataldo and Herbsleb 2008), developer interaction is facilitated by collaborative development environments that capture details of discussion around development activities (Costa et al 2011). Mining such data offers an interesting opportunity to examine implications of the sentiments reflected in developer comments.…”

On negative results when using sentiment analysis tools for software engineering research

Recent years have seen an increasing attention to social aspects of software engineering, including studies of emotions and sentiments experienced and expressed by the software developers. Most of these studies reuse existing sentiment analysis tools such as SENTISTRENGTH and NLTK. However, these tools have been trained on product reviews and movie reviews and, therefore, their results might not be applicable in the software engineering domain. In this paper we study whether the sentiment analysis tools agree with the sentiment recognized by human evaluators (as reported in an earlier study) as well as with each other. Furthermore, we evaluate the impact of the choice of a sentiment analysis tool on software engineering studies by conducting a simple study of differences in issue resolution times for positive, negative and neutral texts. We repeat the study for seven datasets (issue trackers and STACK OVERFLOW questions) and different sentiment analysis tools and observe that the disagreement between the tools can lead to diverging conclusions. Finally, we perform two replications of previously published studies and observe that the results of those studies cannot be confirmed when a different sentiment analysis tool is used.

“…Case studies have found that: parallel changes are a leading cause of defects (one study in a telecommunication system found 98 developers to be working in parallel on the same artifact [21]), coordination issues in distributed development lead to code integration problems [23], developers have difficulty in identifying their impact networkchanges that may impact them or changes that may be impacted [24], and developers spend significant portion of their time in coordinating their efforts [9], [20].…”

Abstract-Software conflicts arising because of conflicting changes are a regular occurrence and delay projects. The main precept of workspace awareness tools has been to identify potential conflicts early, while changes are still small and easier to resolve. However, in this approach conflicts still occur and require developer time and effort to resolve. We present a novel conflict minimization technique that proactively identifies potential conflicts, encodes them as constraints, and solves the constraint space to recommend a set of conflict-minimal development paths for the team. Here we present a study of four open source projects to characterize the distribution of conflicts and their resolution efforts. We then explain our conflict minimization technique and the design and implementation of this technique in our prototype, Cassandra. We show that Cassandra would have successfully avoided a majority of conflicts in the four open source test subjects. We demonstrate the efficiency of our approach by applying the technique to a simulated set of scenarios with higher than normal incidence of conflicts.
