Abstract
Service managers require precise enough measures of service performance to make particular decisions. Generalizability theory (G-theory) has begun to be used to design service assessment studies for decision making. However, initial applications address a limited range of decisions and may underestimate the amount of data needed for decision making if the variance due to the hidden-occasions (time-of-observation) facet is substantial. This study uses test-retest mystery shopping data to investigate the variance due to the main and interaction effects of test occasions and the consequences of ignoring them for different managerial decisions. Accounting for the hidden-occasions facet reveals a need to collect more than twice as many data when benchmarking services and over 10 times as many data to segment service assessors on the basis of their evaluative responses. Thus, accounting for variation due to occasions is crucial for G-theory applications to deliver assessment data of the required quality.

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.
