OCE to measure the personnel performance？
Two perspectives of people performance are skill and attitude. KPI of skill is OCE (Overall contribution effeciency), or APQMIS，which is the abbreviation of Availability, Performance, Quality, Maitenance and improvement, Sustainability.
Generally, the skill KPI measurement can be deployed according to the steps in the followings:
A, Are the people available?
P, Have people perfromed?
Q, Time used enough?
MI, Production situation improved?
S, Level is suatainable or not?
For example:
A，If we have 100 time units in which the on duty time is 80 units, we can get the availability being 80/100 which equals 80%;
P，After the people is on duty or they come to company or working unit, they take 5 time units to attend training, 2.5 units standing by, 2.5 units preparing work reports and then do the normal activity work, the performance will be: P=(80-5-2.5-2.5)/80=87.5%;
Q，Let us presume the time usage rate being 90%;
MI，If MME before maintenance is 99% with post-Maintenance MME being 94%, then MI is 100%-(99%-94%)=95%;
S，We can use standard deviation to measure the sustainability of the people. For example, if it is 5, then S=(100-5)/100=95%;
so we get that OCE=80%*87.5%*90%*95%*95%=56.86%
We can see that it is very difficult to get a high OCE.
OEE
Before you get stressed out with your company’s productivity or the lack thereof, you have to assess what you’re missing. Every company has it, may it be ineffective marketing strategy, disorderly organization, unproductive equipment etc. If you’re having problems with the hardware or equipment used by the firm for manufacturing then a good system is needed to be put in place. This is the moment when smoothly operating equipment is crucial to make substantial returns for the company.
Many experts believe that a lot of processes employ machines to add value to what clients pay for and this is true in a setting that is widely competitive. For instance, a toy company that produces thousands of products daily for the local and international market requires factory machines to work dependably and at their optimum pace to supply products when customers or the industry needs them. But it’s evident that factories throughout the globe are plagued with equipment problems of one kind or another. So it’s essential that company owners understand and evaluate their business’ Overall Equipment Effectiveness or its OEE. Generally, OEE measures how well the equipment is running. It can specifically show how much of the time the machine is actually doing well and what percentage or portion of the output is of good quality, not just the amount of products or output the machine is turning out.
What’s more, OEE is not just for maintenance anymore since the approach can help predict problems in the future and may allow some monitoring of the equipment’s health as well. It involves a step-by-step computation which is part of the general framework. Of course, if you want to know more about the system and how it mainly works then consulting experienced trainers or consultants is the best way to understand the key components and its application.
OLE
OLE is the abbreviation of overall labor effectiveness which is a very effective performance index to measure the people performance especially for low level persons whose salary is based on working unit such as 0.3 euro per loading one pallete or 0.1 $ per folding one box etc. And the maintemance work is also treated as this theory recently such as 3 $ per motor change or 2100 $ for one third party contract overhall etc. If treat such human resources supplier or department as one unit, we can meaure every human resource effectiveness easily using OLE.
When such a person is hired to maintain the machines effectiveness, for example, mechanical machine effeciency or MME, then the theory time the person can work 100% is hiring time or solar time somebody called. Of couse he has some time to leave for holidays or sickness etc. which is treated as absent time. And he also needs training, feeding and travel etc which is called setup time.
Then OLE of such person is calculated as the followings,
Availability=(Solar time-absent time)/Solar time
Performance=(Solar time-absent time-setup time)/(Solar time-absent time)
Quality=Weighted MME*(Solar time-absent time-setup time-service cost per 000 litre/allowance per time unit)/(Solar time-absent time-setup time)
OLE=A*P*Q

What is PKE?
PKE stands for Process Kaizen Engineering, where
Kaizen= continuous improvements
The PKE is therefore the Engineer for Continuous Improvement.
What is TPM?
TPM is the abbreviation of total productive manufacturing.
It is not just a program. It is a long term production efficiency improvement process to attain a predictable manufacturing environment.
Through total involvement of the entire workforce, the quality of product and machine uptime can be improved by continuously improving the equipment performance. TPM can also reduce total production and maintenance costs.
