The item measures of the TPM pillars and OEE

ConstructItem codeItems
Autonomous Maintenance (AM)AM1In our company, machine operators have given the responsibility/autonomy/for basic maintenance tasks, rather than relying on dedicated maintenance technicians. Operators perform maintenance tasks on their own equipment emphasizing proactive and preventative maintenance
AM2The operators are empowered and able to do simple maintenance tasks (cleaning, lubrication, fixing minor errors, tightening nuts and bolts and safety checks) themselves
AM3Our company tools required to perform routine maintenance, checks, setups, etc., are identified and stored using 6S (sort, set in order, shine/sweep, standardize, sustain and safety) principles
Education and Training (EduT)EdT1In our company, operators are given necessary education and training on maintenance engineering practices timely
EdT2All employees associated with the focus equipment value stream (operators, supervisors, management, quality assurance, engineering, maintenance, etc) received proper training and they have the necessary skills and knowledge
EdT3In our company, all maintenance related training/operating materials are available and accessible to the concerned person
EdT4In our company, maintenance skills gaps are identified, prioritized and filled through training timely
Safety, Health and Environmental Management (SHE)SHE1In our company, there is good maintenance management which avoids accidents during maintenance activities
SHE2In our company, all maintenance activities are environmentally friendly
SHE3Environmental, health and safety (EHS) risk assessment associated with the equipment (machine guarding, electrical hazards, personal protective equipment (PPE) assessments, etc) is reviewed and updated timely
SHE4All operators, mechanics, technicians (and others as appropriate), have been informed of all specific environmental, health and safety (EHS) hazards and associated control measurements that must be maintained
Overall Equipment Effectiveness (OEE)OEE1Our machines produce high quality/defect free/products
OEE2The performance of our machines is very high. Our machines are effective and efficient
OEE3Our machines run for a long time without failure. The availability of our machines is high
Planned Maintenance (PM)PM1In our company, problems are fixed at the right time while they are minor to reduce repair costs
PM2Properly planned maintenance practices are being performed
PM3Preventative maintenance requirements have been established for the equipment at a defined frequency
PM4Critical spare parts have been identified and are stored near the equipment (as appropriate)
PM5There are sufficient signs and labels that play a crucial role in a successful planned maintenance system. For example, every lubrication points have been labeled to identify the type of lubrication that should be used
Early Equipment Management (EEM)EEM1When it's time to choose new equipment or develop new products, we consider previous experiences to make maintenance easier in the new machine
EEM2There is an effort to design our machines for easy, infrequent and inexpensive maintenance
EEM3Life cycle costs are considered in early management process with variable results
EEM4There is an effort to design our machine for safety. For example, an effort to protect an operator from injury during machine breakdown
Quality Maintenance (QM)QM1In our company, cost of poor-quality losses is measured and addressed linking back to the process
QM2In our company, process capability issues are analyzed and investigated timely
QM3In our company, product quality risks are managed timely and appropriately
QM4Existing quality management systems and tools are used to identify and resolve issues affecting the quality factor of OEE
Office TPM (OTPM)OTPM1In our company, administrative workers and managers work in harmony with other employees
OTPM2Our administrative offices are responsive and flexible to respond to changes in our customer requirement and that ensured a strong brand image of the company
OTPM3In our company offices, all tasks completed on time within standard working hours
OTPM4There is clear and consistent communication between managers and employees about strategies and goals of maintenance which builds a strong foundation of manager-employee relationship in our company
OTPM5There is continuous process improvement practice in administrative offices
Focused Improvement (FI)FI1In our company, there are team-based, structured improvement activities, aimed to eliminate or reduce all possible losses to improve safety and productivity and reduce defects and production costs
FI2The maintenance team is proactive, willing to try new methods
FI3There is great effort aiming at creating a continuous improvement culture in maintenance related activities
FI4There is comprehensive loss analysis to measure and analyze the current maintenance related losses contributing to productivity, efficiency or cost loss
FI5In our company, standards established for cleaning, inspection, lubrication and tightening operations
