Do Not Be Misled by O.E.E.

Measure of Equipment Effectiveness Often Misused

By Robert M. Williamson, president of Strategic Work Systems

Overall equipment effectiveness (O.E.E.) has been used as one of the more important "maintenance metrics" since Total Productive Maintenance (TPM) came to the U.S. in the late 1980s. O.E.E. is the primary measure used in TPM to identify and quantify the major equipment-related losses and a metric for rating "equipment effectiveness." O.E.E. has become widely used in many plants with or without the elements of TPM in place since the early years of TPM to quantify equipment effectiveness losses. This usage has also caused some confusion and has led to many misuses of the O.E.E. percentage calculation.

Detective Maintenance

When we think about maintenance strategies, the words predictive, preventive, corrective, and breakdown spring to mind. There is however an important class of tasks that we do to ensure that our equipment and Plant remains safe and productive. These tasks are based on a Detective Maintenance strategy. They help us win our licence-to-operate and ensure long term viability. With machinery and Plants becoming increasingly more complex, the proportion of such tasks in the total maintenance program is growing.

Managing a business efficiently means that we have to manage risks well. In turn, this requires that our safety devices and systems work on demand. It is possible to arrive logically at the required availability of the items in question and find suitable detective maintenance strategies. While analysis is relatively easy, there are several hurdles in implementing their results. These challenges can be met by a range of solutions. They are not universal and need to be tailored to each situation.

The word pro-active is very popular, especially in the maintenance context. Detective Maintenance strategies are pro-active. More importantly, they are essential to long term success.


Where do we end our probe in Root Cause Analysis?

One of the biggest confusion in an attempt to perform a thorough Root Cause Analysis is understanding how deep should we pursue our analysis or simply stated, where do we stop our investigation in performing a Root Cause Analysis? Going to deep will lead us to the bible, Timothy 6:10, For the love of money is a root of all evil and going to shallow will allow the problem to recur again and again.

Maintenance Inventory and Purchasing

The inventory and purchasing staff have the largest impact on maintenance productivity than any other support group.

An interesting statement; but how does inventory and purchasing affect the maintenance organization?

How High, How Far and How Fast —Assess Your Organization

What improvements is your organization pursuing? It is likely that your management has spent a lot of time reviewing best practices and evaluating which ones can provide the needed performance improvements. But has any effort been expended to determine which of these best practices are "doable" within your organization?

Managing the Complete Motor System

Modern management practices often do not take into account the importance of motor systems maintenance and management requirements. Through efforts in cost control, many industrial and commercial firms reduce maintenance staffs, take least cost approaches to corrective actions and sacrifice preventive maintenance programs.

Road to Gold

Hamilton Sunstrand quest to achieve UTC's Ace Gold Status by Steven Piazza, Hamilton Sunstrand (Winner Uptime Magazine PdM Program of Year Award Best Ultrasound Program for 2007)

The maintenance aspect of our jobs would be easy if we could have the advanced knowledge of machinery and equipment failures. By closely predicting the life cycle of parts and equipment it would be simple to schedule the repairs and the replacement of equipment and manufacturing systems. As we all know, accurate and timely scheduling team up to drive the effectiveness and efficiency of our maintenance resources.

Inventory Management Strategies

By Randy Walker

1) Introduction to Inventory Management

For Facilities Maintenance Organizations, the quickest and most substantial "hard dollar" returns are achieved through the Inventory and Purchasing modules. Even in Equipment-centric Organizations, where the emphasis is on uptime and asset efficiency, the savings from improved materials management can be sufficiently large to cover the cost of purchasing and implementing a CMMS project.
