Itdoes not take account of equipment costs and profits, and so it is not a goodmeasure for comparing machines or systems, or for comparing the effect ofequipment deterioration over time. OEE is only a part of the Life Cycle RiskCost/Profit perspective. Within those inherent limitations the OEE concept is usefulfor monitoring equipment effectiveness and performance.http://www.bin95.com/9

SAMPLE of Total ProductiveMaintenance Training Power Point soldby BIN95.comTotal Productive Maintenance is operator driven reliability:The Operators’ Creed of TPM – Keep it clean Keep it lubricated Monitor for degradation Maintain it before production is affected Simplify and improve itBreakdownsSetup nsZEROStoppagesZEROOperators are likely to recognise before anyone else that a machine needs to bereplaced or overhauled, or a system modified.David Sherwin, Maintenance and Reliability Professor, tells us that machinedeterioration is slowed under TPM by the primary care given to the machine by itsoperator. The operator can delay the need for maintenance by focusing on keyequipment health factors. TPM does not exclude Preventive Maintenance (PM) bytechnicians, in fact it is required, but there is no specific strategy for it within TPM,and it is almost bound to be neglected if the factory gets too busy, which is justwhen it is most needed. To address this risk the PM work is planned and scheduledby the maintenance group.http://www.bin95.com/12

SAMPLE of Total ProductiveMaintenance Training Power Point soldby BIN95.com7 Visual Quality Management Tools forTPM Problem SolvingIn a TPM program the Team are always looking to ‘see’ what causes the problems so thatthey know when it is time to act, and know what problem needs to be fixed. The sevenvisual quality control tools help to identify relationships and notice interactions between arange of factors that affect the problem. You come to understand better what to do.www.lifetime-reliability.comWhen solving a problem it is necessary to know what to do and what is, or is not,working. The 7 quality control tools shown on the slide let us view a problem in anumber of ways to help pinpoint the issues. They are used by the TPM team toanalyse the factors that have the greatest influence on a problem and to focus theirefforts for the highest payback when fixing the problem.http://www.bin95.com/46

SAMPLE of Total ProductiveMaintenance Training Power Point soldby BIN95.comProviding the whole ‘TPM Mix’Vision Targets Team . Processes . Measurementwww.lifetime-reliability.comHopefully you are now more aware of what TPM will require of you and yourorganization. It has more to do with managing change and challenging mindsetsthan introducing a new way to run your operation. In time your productionequipment will be managed by the people on the ‘shopfloor’, while managers will bemore focused on developing new business opportunities. In order for this to happenthe people now running your plant and equipment will need to learn how to run theirmachines well. More importantly they will need to learn how to improve theproduction equipment so it can perform at highest productivity and efficiency. TPMis a process to let people master the skill they need to do that.http://www.bin95.com/58

The ‘no cost’ measures are the ‘early wins’ in Bill’s case study.We’ll only get Walt’s support if he can see the benefit of TPM.In that case we need to make justification a high priority in our planning.www.lifetime-reliability.comThe bullet points from the ‘Change Management Matrix’ become the requirementsand actions to be undertaken and achieved as the plan to make TPM part of normalbusiness practice unfolds.http://www.bin95.com/82
