Abstract
During a 12-year period (2011-23), the number of staff in the Clinical Engineering (CE) Department at the Children's Hospital of Eastern Ontario (CHEO) increased from five to more than 20 biomedical equipment technicians/technologists. However, despite this increase in staff, processes did not evolve and procedures that used modern technological and shipping advances were not implemented. The absence of standardized procurement and inventory processes for parts created discrepancies between on-hand inventory and the computerized maintenance management system (CMMS). Owing to inaccurate CMMS information and unsystematic parts documentation, time and money were wasted. This situation led to a lack of confidence in CMMS data, causing staff disengagement, loss of accountability, and limited parts tracking. The current article describes a project that used Lean methodologies and use of the define, measure, analyze, improve, and control structure, including tools such as interviews, a survey, process mapping, and Gemba walks, to create a list of prioritized problems. A total of 16 problems were formulated, four of which were identified as prerequisites to be implemented regardless of prioritization. The four prerequisites described the scope of each problem and potential solutions. The goal of this process was to create a workflow that could save time and money while improving the morale of stakeholders involved in the parts procurement and inventory process.

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
