Key differences among TPM maturity models
| Features | Shaaban and Awni (2014) | Alidrisi (2020) | Proposed HDG TPM 5.0 model |
|---|---|---|---|
| Maturity levels | 3 stages (Pilot, Deployment, Continuous Improvement) | 5 levels (Basic to World Class) | 5 levels extended to HDG multidimensional structure |
| Focus areas | TPM pillars | TPM pillars | TPM pillars + HDG dimensions |
| Digital dimension | Not addressed | Not addressed | Explicitly modelled across all pillars |
| Human dimension | Limited | Limited (AM only) | Explicitly modelled across all pillars |
| Green dimension | Not considered | Not considered | Explicitly modelled across all pillars |
| Scoring logic | Qualitative categorisation | Quantitative per pillar | Three-layer scoring: Overall→ HDG (2D)→ TPM pillars on HDG space (3D) |
| Normalisation | Implicit; based on qualitative expert judgement | Firm-specific bounds (non-comparable) | Cluster-referenced, comparable across firms |
| Weighting mechanism | Static | Static fuzzy linguistic weights | Contextual weighting (sector*size*item relevance) + dynamic updates |
| Benchmarking logic | Not defined (case-based insights only) | Global ranking | Cluster-specific, context sensitive |
| Explainability | None | None | Integrated |
| Qualitative input | Not systematically included | None | NLP-driven analysis, drift detection |
| Operator interface | N/A | N/A | Interactive dashboard and chatbot |
| Improvement recommendations | General advice | Implicit logic | Data-driven (based on cluster frontrunners' practices), dimension- and pillar-specific |
