OEE Integration – Part V

Defining overall equipment effectiveness (OEE) criteria as part of the scope of work or purchase order agreement is quickly becoming standard practice throughout the automotive industry and manufacturing in general. OEE Assessments OEE criteria should be performed for every new purchase.  Often times, a high speed machine may be incorporated into a mixed technology production environment.  It is also possible that the […]

OEE Integration – Part IV

OEE and APQP – New Equipment / Program / Process Launch In parts I – III we discussed the role of leadership to define policies and procedures.  We also discussed developing the infrastructure of your team through training and development.  However, this still doesn’t put OEE at the forefront of your company.  If the goal of your company is to achieve world class […]

Upcoming Topics for March 2009

We have received several topic requests that we will work on for the month of March, 2009.  If you have a topic that you would like to see featured on our site, send an e-mail to LeanExecution@gmail.com. OEE on the Shop Floor – Measurement:  What should we be measuring to make OEE practical at the shop floor level.  What factors […]

OEE and Capacity Management

Capacity – Available or Required? From a scheduling perspective it is very easy to determine how much capacity (or time) will be required to manufacture a minimum quantity of parts.  However, it is not just a matter of multiplying the Standard Cycle Time by the Quantity of Parts and dividing by the part or process OEE %. As you may recall, the availability component of […]

Availability and OEE

What is Availability? In its simplest form, availability measures the uptime of a machine or process against the planned production time.  As one of the factors of Overall Equipment Efficiency (OEE), Availability is expressed as a percentage.  The uptime is calculated by taking the difference between the planned production time and total duration of the downtime events that occurred during the planned production period. We […]

Variance, Waste, and OEE

Variance is Waste. Variation and OEE are complementary metrics that need to be considered together.

OEE and Standardized Work

Overall Equipment Efficiency (OEE):  Standardized Work After you start collecting OEE data for your processes, you may notice significant variance between departments, shifts, and even employees performing the work.  Of the many aspects that you will be inclined to investigate, standardized work should be one of them. Making sure that all employees are executing a process or sequence of processes […]

Practical OEE – How To Calculate and Use Weighted OEE

We have presented the methods of calculating OEE for a process and also demonstrated how weighted OEE is calculated for multiple processes.  Our next challenge is to determine how this data can be used to make sure we are targeting the right processes for improvement. Over the next few posts, we will show you how to calculate weighted OEE factors for each process.  […]

Weighted OEE: How To Calculate Total Plant OEE

In this post we will present a simple method to calculate a truly weighted OEE, including weighted factors Availability, Performance, and Quality. The QUICK weighted OEE method: Recalling our original definition of OEE, we are measuring how effectively our planned production time (net available time) is used to make a quality (saleable) product.  The weighted OEE then is the total time […]

How to Calculate OEE – The Real OEE Formula with Examples

A lot of time and effort is wasted collecting and analyzing data and the results.  Fortunately, Overall Equipment Effectiveness, or OEE, is one of those metrics that is easily calculated and can be applied to any process, department, or the entire organization. We have created  a number of Excel spreadsheets that are immediately available from our FREE Downloads page or from the […]
