Abstract
The objective of this paper is to identify tools and methodologies to increase productivity in commercial steel fabrication shops. The effectiveness of these tools and methodologies has been demonstrated through a case study in a Canadian steel fabrication shop. Three different productivity improvement concepts were identified as suitable for the steel fabrication environment. Lean, Six Sigma, and the Theory of Constraints (TOC). Lean was retained as being the most suitable to steel fabrication due to its low cost, focus on quality, and built in continuous improvement process. In the case study, Lean tools were identified and applied to address three top productivity issues. A baseline was established for existing productivity for a fitting station over a period of two weeks. Selected tools were implemented, and a session was conducted to educate the workers on the new processes and tools. Lastly, the productivity was recalculated, the results were analyzed, and recommendations were made.

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
