Broadcast vs. Unicast Review Technology: Does It Matter?
Bibliographic record
Abstract
Code review is the process of having other team members examine changes to a software system in order to evaluate their technical content and quality. Over the years, multiple tools have been proposed to help software developers conduct and manage code reviews. Some software organizations have been migrating from broadcast review technology to a more advanced unicast review approach such as Jira, but it is unclear if these unicast review technology leads to better code reviews. This paper empirically studies review data of five Apache projects that switched from broadcast based code review to unicast based, to understand the impact of review technology on review effectiveness and quality. Results suggest that broadcast based review is twice faster than review done with unicast based review technology. However, unicast's review quality seems to be better than that of the broadcast based. Our findings suggest that the medium (i.e., broadcast or unicast) technology used for code reviews can relate to the effectiveness and quality of reviews activities.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
