OEE Calculation Errors

Database Errors We agree that collecting and tracking OEE data is a task best suited for a database, however, all the bells and whistles of an OEE system don’t serve much purpose if the calculations are wrong.  Before you make a significant investment in your OEE data collection, tracking, and monitoring system, make sure the system you plan to purchase […]

OEE and LEAN

Incorporating and tracking performance using Lean metrics doesn’t make a company Lean any more than tracking weight puts you on a diet.  Measurements are like decisions, nothing changes unless actions are taken. How does this apply to OEE?  How does OEE apply to LEAN?  As we’ve mentioned in previous posts, many companies invest a significant amount of time, money, and effort to develop exorbitant […]

OEE Measurement Error

How many times have you, or someone you know, challenged the measurement process or method used to collect the data because the numbers just “don’t make sense” or “can’t be right”? It is imperative to have integrity in the data collection process to minimize the effect of phantom improvements through measurement method changes.  Switching from a manual recording system to […]

OEE For Dedicated – Single Part – Processes

OEE For Dedicated – Single Part – Processes Definition:  Dedicated – Single Part – Process:  A process that produces a single product or slight variations on a theme and does not require significant tooling or equipment changeover events. A single part process is the easiest application for a OEE pilot project.  The single part process also makes it easier to demonstrate […]

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.

Problem Solving with OEE – Measuring Success

OEE in Perspective As mentioned in our previous posts, OEE is a terrific metric for measuring and monitoring ongoing performance in your operation.  However, like many metrics, it can become the focus rather than the gage of performance it is intended to be. The objective of measuring OEE is to identify opportunities where improvements can be made or to determine whether the changes to your […]

OEE for Multiple Parts – Single Machine (Multipart Processes)

How to Calculate OEE for Single Machine and Multiple Parts. Flexible manufacturing provides the advantage of producing many different parts on the same piece of equipment.  The same is true for processes such as stamping presses, molding machines, or machining operations. The first question most often asked is, “How do we calculate OEE for a piece of equipment that is capable of manufacturing multiple […]
