Specialization as a <scp>double‐edged</scp> sword: The relationship of scientist specialization with R&D productivity and impact following collaborator change
Bibliographic record
Abstract
Abstract Research Summary Organizational learning studies demonstrate that specialization conditions multiple aspects of firm performance, including productivity and financial returns, through its effect on skill development and coordination. We know little, however, about how specialization may influence a firm's R&D performance, including both R&D productivity and innovation impact. We propose that specialization is a double‐edged sword for R&D performance that can be influenced via changing scientists' collaborators: specialization increases scientist and firm R&D productivity but decreases the impact of innovations, while changing collaborators in a team reverses how specialization relates to productivity and impact. We validate this argument using a long panel (1970–2017) from the biotechnology industry. Specialization and collaborator change may thus serve as mechanisms to manage the trade‐off between productivity and impact in R&D activities. Managerial Summary This article studies how managers in firms may leverage their R&D workers' specialization to optimize their R&D performance. Our study shows that specialization is a double‐edged sword for R&D performance: it facilitates R&D productivity at the detriment of R&D impact, while the trade‐off shifts when collaborators within a scientist's team change. Thus, specialization and collaborator change condition R&D performance, with two implications for strategy. First, a firm's managers can recruit specialists or generalists depending on whether they want to prioritize productivity or impact in R&D activities. Second, job rotation practices that create periodic collaborator change may disrupt R&D productivity, yet invigorate explorative activity and increase the likelihood of impactful innovation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
