Impact of C07 on weights

Item IDDimension–Pillar and item focusEffect on cluster percentiles (α)Effect on entropy (β)Effect on SHAP relevance (γ)Implication for qjt+1
ID3D-PM: use of IoT devices and real-time sensors for equipment health monitoringWidens the gap between upper and lower quantiles due to C07’s low adoptionHigh dispersion preservedHigh SHAP, as it strongly contributes to the Digital deficitPotential weight increase (emerging differentiator)
ID5G-MP: energy monitoring and improvement actions in maintenance operationsReinforces a low lower-quartile, confirming systematic underperformanceModerate entropy (stable weakness across firms)Moderate SHAP as a persistent negative driverSlight weight increase (still discriminative)
ID12D-OTM: cross-functional use of digital tools in operations and teamworkConvergence of scores around the upper quantilesEntropy decreases (practice becoming standard)Low SHAP, as it no longer explains maturity differencesLikely weight decrease (no longer informative)
ID18G-FI: integration of eco-efficiency criteria in inspection and quality routinesIncreases heterogeneity in the central and upper quantilesEntropy increases (diverging adoption patterns)High SHAP for explaining the Green deficitPotential weight increase (key indicator of G maturity)
ID22H-T&E: frequency and coverage of operator training and education in maintenance-related tasksUpper quantiles further consolidated at high valuesLow entropy (uniform good practice across the cluster)Low SHAP, as it rarely drives maturity differencesLikely weight decrease (mature, non-discriminative item)
