6 TPM-A Route to World-Class Performance

To the machine or process
0 Ineffective raw material and tool marshalling
0 Lack of forklift and/or forklift driver availability
0 Inadequate access to the machine or process

From the machine or process

0 Inadequate take-off /take-away facilities (i.e. track reliability)
0 Upstream/downstream bottlenecks
0 Poor shift handover arrangements
Finally, the value chain OEE measure is a senior management key performance
indicator, typically aimed at highlighting the following.

Suppliers

0 Poor procurement procedures
0 Poor quality and/or lack of consistency of incoming materials/
components

Customers

0 Lack of responsiveness to customer call-off changes
In our experience, part of the essential planning and scoping stage prior to
TPM implementation is a detailed assessment of the three OEE levels outlined
above. Do not be surprised if well over half of your lost opportunity costs or
costs of non-conformity lie outside the machine or process OEE.
In reality, overall equipment effectiveness measures how well a company’s
production process or individual piece of equipment performs against its
potential. Through the best of best calculation, it also indicates a realistic and
achievable target for improvement.
Not only that, but due to the linkages with the hidden losses, it identifies
the technique which can best address the type of problem. (Each loss has a
different TPM approach to resolving it.)
The outcome of a low OEE is a reactive management style. Here the root
cause of many of the unplanned events throughout the organization can be
traced back to the production process. As OEE is raised through TPM,
opportunities are presented to drive out waste and improve customer service.
The route to TPM encourages teamwork and cross-functional learning. As
such, TPM provides a mechanism to deliver change when directed correctly,
which can have a powerful impact on company-wide perceptions and attitudes.
An improving OEE indicates:
how successful the organization is at achieving what it sets out to do;
0 success in establishing a continuous improvement habit;
buy-in to the company vision and values;
