More than 200 maintenance best practices evaluations structured in 8 categories and 40 areas, enabling to maintenance strengths and weaknesses in a detailed and a consolidated view
One axis of the assessment is to idenfity the level of Maintenance " Integrated Preventive Maturity" not only in the direct "Preventive Maturity Level" but in all the related areas (starting by the strategy...)

Brief description of the questionnaire
The assessment covers all maintenance, from basic and corrective maintenance to full preventive maintenance at the strategic, tactical and operational levels, as well as the dimensions related to people, external resources and procurement in the following areas:
Strategy and improvement
- Maintenance strategy (corrective vs preventive, cost vs reliability...): does the strategy address the right topics (type of maintenance, objectives, outsourcing...), whether defined on site or centrally (if multi-site company) and how is it communicated?
- Outside in: is there active monitoring of maintenance methods outside the company?
- Strategic and improvement plans: are there plans for implementing the strategy or improving maintenance, how are they defined and what are their contents?
Preventive maturity level :
- Definition and application of the maintenance policy: how is the maintenance policy effectively defined and applied? What analyses and methodologies are used to define it? Is it well adapted to the type of equipment?
- Critical analysis of the equipment: is the critical analysis of the equipment carried out regularly using the correct methods and statistical analyses (MTBF, MTTR...)? Are the objectives clear?
- Total Productive Maintenance: Are the principles of TPM clear, implemented and monitored?
- Reliability program: Does the maintenance policy answer the 7 questions of reliability-centered maintenance? What is the level of competence and experience of maintenance personnel on reliability enhancement methods?
- Predictive and planned maintenance: Is there predictive maintenance and how is it monitored? Is it based on reliable mathematical models? How is the planned maintenance plan constructed and does it contain elements other than regulatory?
- Root cause analysis: are these analyses conducted regularly with the right methodologies and based on historical data?
Daily operations (and management):
- Technical data management: is there a complete, up-to-date and hierarchical nomenclature of equipment and sub-equipment?
- Standard procedures for corrective and preventive measures: are there standardised procedures, with the right level of detail and up-to-date? Are standard times defined?
- 5S : Is the 5S methodology being used effectively?
- Work request content and system: Is the work request process clearly defined from start to finish, from the initial request to the handover of equipment to production, with clear roles and responsibilities and a validation/prioritisation mechanism?
- Computer Maintenance Management System (CMMS): Is a CMMS used and for which functions?
Planning and priorities
- Daily, weekly and medium-term planning (for corrective and preventive maintenance): how are the different intervention schedules established, executed and monitored?
- Priorities and application of rules: have priority rules been defined according to the maintenance policy, the criticality of the equipment, the type of incident? Are they applied?
- Planned shutdown: how are major maintenance shutdowns planned and executed (a few hours to 2-3 days, excluding "major shutdowns")
- Planning ratio: what are the proportions of planned operations?
- Maintenance objectives, KPI and dashboard: how are objectives and indicators defined and are they consolidated in a dashboard? How are they reviewed?
- Cost management: which costs are monitored and how?
- Management meetings: Are maintenance management meetings effective and do they allow the right decisions to be made and actions to be monitored?
- Transfer to production: are the new equipments put into production with a procedure allowing their proper functioning and control by the production?
- Technical project management: Are projects managed with effective project methodologies?
- Investment process and decision: is the investment process formalized, with clearly defined steps? Does the decision-making mechanism allow rational and informed decisions?
- Design for maintainability: is maintainability taken into account when designing or purchasing new equipment?
Spare parts and tools
- Spare parts inventory policy and management: is the policy defined and implemented? Are the management parameters known and monitored to avoid shortages or excessive stocks?
- Procurement process: Is the procurement process clearly defined, with the right responsibilities, criteria and decision levels?
- Tool management: how are individual or collective tools managed?
Organisation and people
- Organisation: are the roles and responsibilities clear between the different members of the maintenance team, the production teams, the engineering... ? Is maintenance-production cooperation good?
- Internal skills: is the level of competence of the different maintenance members sufficient and how are the skills managed and developed?
- Subcontractor management: how are subcontractors managed and monitored since the tender phase?
