Abstract
Data envelopment analysis (DEA) is increasingly used to measure projects' efficiency, as recent research contributions indicate. However, most studies in project management take the axioms and assumptions underlying DEA for granted or do not pay attention to the type of data they are working with. Lack of attention to these important factors leads to selection of inappropriate DEA models and, consequently, produces biased efficiency scores. In this paper, after arguing that DEA is an appropriate model for project efficiency measurement, the economic meaning of its axioms and assumptions is explained. We also explain how different data types require some modifications in the CCR model. As a result, a guideline is presented to help future project management scholars select an appropriate DEA method tailored for their specific situation. Further, to highlight the importance of paying attention to these issues, we empirically demonstrate the high sensitivity of DEA results to the applicability of underlying DEA axioms and assumptions.

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 it
