You can’t even ask them to push a button: Toward ubiquitous, developer-centric, empirical software engineering

Philip Johnson Department of Information and Computer Sciences University of Hawaii

October 31, 2001



Collection and analysis of empirical software project data is central to modern techniques for improving software quality, programmer productivity, and the economics of software project development. Unfortunately, barrierssurrounding the cost, quality, and utility of empirical project data hamper effective collection and application in many software development organizations.

This paper describes Hackystat, an approach to enabling ubiquitous collection and analysis of empirical software project data. The approach rests on three design criteria: data collection and analysis must be developer-centric rather than management-centric; it must be in-process rather than between-process, and it must be non-disruptive—it must not require developers to interrupt their activities to collect and/or analyze data. Hackystat is being implemented via an open source, sensor and web service based architecture. After a developer instruments their commercial development environment tools (such as their compiler, editor, version control system, and so forth) with Hackystat sensors, data is silently and unobtrusively collected and sent to a centralized web service. The web service runs analysis mechanisms over the data and sends email notifications back to a developer when “interesting” changes in their process or product occur.

Our research so far has yielded an initial operational release in daily use with a small set of sensors and analysis mechanisms, and a research agenda for expansion in the tools, the sensor data types, and the analyses. Our research has also identified several critical technical and social barriers, including: the fidelity of the sensors; the coverage of the sensors; the APIs exposed by commercial tools for instrumentation; and the security and privacy considerations required to avoid adoption problems due to the spectre of “Big Brother”.
