Abstract

fetched live from OpenAlex

Obtaining an accurate characterization of pre-release changes, especially those related to fault corrections, can give indications for the quality of the software development process and its product. The resulting indications can then be leveraged to identify areas for quality improvement within software development organizations. Towards this objective, we studied the evolution of the source code modules in an industrial enterprise resource planning software system spanning a time period of two years from the initial creation of the source code modules to the release of the software product. In this paper, we describe our case study process, and present the frequency distributions of pre-release changes and faults along with lessons learned from the case study. Overall, we found that (a) only 22% of pre-release changes contribute new functionality to the system under development; the remaining majority of the pre-release changes are either fault corrections or code clean-ups (b) over 72% of pre-release faults are propagated from upper-stream requirements and design activities (c) fault classes that are the target of most fault detection tools have a low frequency.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
