OEC TPM Maturity Diagnostic Toolkit (PowerPoint PPT Deck & Excel Workbook)

Stop trophy-hunting and start transforming. Evaluate your shopfloor reality objectively with a rigorous, JIPM-aligned diagnostic built to eliminate score inflation and chart a calibrated roadmap to sustainable TPM excellence.

This toolkit is optimized for a half-day (4-hour) collaborative session with 6–8 key cross-functional team members:

• Hour 1: Calibration & Alignment – Core purpose briefing, rubric walkthrough, and strategic assignment of peer-pillar scoring matrices.

• Hour 2: Consensus Scoring Session – Cross-functional review of the pillars using the PPTX rubric; entry of raw consensus data directly into the Excel tool.

• Hour 3: Shopfloor Verification Walk – Execution of mandatory "absence of evidence" walks on random machines to resolve any scoring conflicts of $\ge$ 2 levels.

• Hour 4: Strategic Action Planning – Mapping out prioritized gap-closure plans using the automated radar dashboard and the prioritized sequencing engine.

Glossary of Key Terms

• JIPM: Japan Institute of Plant Maintenance, the world's premier awarding and certification body for TPM excellence.

• Pillar Imbalance: A sharp visual variance on the evaluation radar chart indicating uneven deployment, where certain technical pillars lag significantly behind others.

• Score Drift: An artificial, unearned inflation of maturity scores over time that fails to correlate with an improvement in physical operational results (e.g., OEE or breakdown frequency).

• Absence of Evidence: A strict shopfloor verification protocol focusing on identifying missing standards or live defects on random machinery, rather than relying on manicured "model areas."

• Maintenance Dojo: A dedicated, hands-on shopfloor training station or skill-simulation lab used to bridge the gap between classroom concepts and practical, physical maintenance mastery for operators and technicians.

• CBM & TBM: Condition-Based Maintenance (actions triggered by real-time machine health indicators and diagnostics) and Time-Based Maintenance (preventaCan you increase tive actions performed at fixed calendar or runtime intervals).

• MP Information (Maintenance Prevention): Technical design and operational data collected from existing equipment failures, utilized during the Early Management (EM) phase to design new machinery that is inherently reliable, safe, and easy to maintain.

Frequently Asked Questions

1. Does the OEC TPM Maturity Diagnostic replace the official JIPM self-checklist? No. It does not replace the official JIPM checklist C or self-checklist. Instead, it serves as a rigorous strategic precursor. While the official JIPM documents focus heavily on compliance auditing, this diagnostic serves as an independent development tool engineered to build a calibrated, actionable improvement roadmap before you invite external auditors.

2. Can this diagnostic be used across multiple manufacturing sites? Yes. Because the toolkit establishes a standardized 4-level rubric across all 40 dimensions, it is an ideal corporate benchmarking tool for multi-site operations directors to evaluate, compare, and track TPM maturity consistently across different plants.

3. Is there detailed guidance provided to the assessors on how to conduct the assessment based on the diagnostic fairly and properly? Yes, the toolkit contains a dedicated companion document—Guidelines for Assessors—designed to eliminate individual bias and cross-functional scoring inflation.

4. Can individual team members fill out the assessment separately? Yes, team members can complete the assessment independently as a pre-work exercise, but the tool is explicitly engineered to be finalized through a collaborative, cross-functional workshop. Individual scoring often suffers from localized bias; true site calibration only occurs when the steering committee aligns and establishes a single consensus score per dimension.

5. How does the toolkit handle disagreements in scoring during a workshop? The toolkit includes a built-in facilitation safeguard: if team members have a scoring disagreement of two or more levels, it triggers a mandatory shopfloor verification walk. Assessors leave the conference room to audit a random machine and interview frontline operators to find physical evidence, resolving the conflict objectively.

6. Is there a summary score table and an automated radar chart included? Yes. The Excel Scoring & Dashboard Tool contains a dedicated "Pillar Summary" tab. As soon as you select your maturity levels on the Score Entry sheet, a consolidated summary table and a high-resolution radar chart update automatically to visually highlight "pillar imbalance" for your leadership briefings.

7. What is the Achievement Sheet and how do JIPM award applicants use it correctly? The Achievement Sheet is a mandatory JIPM document required at the time of award application. It serves as a data-driven verification layer that prevents plants from claiming high maturity based solely on governance structures or meeting frequencies.

8. What software is required to run the toolkit? The presentation files are delivered in Microsoft PowerPoint (PPTX) format, and the scoring engine is built in Microsoft Excel (XLSX). No custom plug-ins or external software installations are required.
