xiv Glossary of TPM terms
At each Milestone there will be audits to establish your capability in
transforming the business and further planning to take into account the future
changes required to meet customer and market needs, as well as the
organization’s needs. For each milestone your management team will have
defined goals and targets as Pillar Champions, that should be realized having
reached each of the milestone stages.
Improvement Zone (IZ): This is a geographical area where the First Line
Managers and their teams apply the basic techniques of TPM and CANDO/
5s. This area is a manageable but representative portion of the process or
plant which when improved, will provide an important contribution to the
business.
Key Contact: These are support personnel, usually from the functional
departments like Finance, Design, Engineering, Laboratory, or individuals
with specialist knowledge. They will gradually get involved either with an
improvement project for themselves or using their specialist knowledge to
support an improvement team. Their aim is to support organizational learning
and problem resolution using the tools of TPM.
Maintainability: This refers to how easy it is to gain access to the equipment
and the particular skills needed to diagnose a problem.
Measurement Cycle: The first stage of a TPM Improvement Plan, consisting
of collecting equipment history, calculating the OEE and assessing the Six
Losses.
Minor Stoppage: When a machine is stopped for a relatively short period
(e.g. to clear a blockage) and then re-started without the need for any repair.
A minor stop therefore causes an Operator to have to interfere with the
process, but does not require the attendance of a Maintenance Technician.
Nine Step TPM Improvement Plan: This is a set of steps the Core Teams
progressively go through when analysing the Pilot Plant/ Area. It enables
them to understand the equipment, measure the problems, analyse then fix
the condition of the equipment and lastly pass on specific technical or support
issues still to be resolved. By doing so the teams will improve the equipment,
but more importantly they will discover the real reasons why the equipment
is in the condition we see it and why it’s not performing in the way we would
want. Some of these issues can be fixed quickly and some are more long term.
Only the critical plant and equipment will be subject to the 9 Step Improvement
Plan.
OEE A measure used in TPM to calculate the percentage of actual effectiveness
of the equipment. Taking into consideration the availability of the equipment,
the performance rate when running and the quality rate of the manufactured
product measured over a period of time (days, weeks or months). The difference
between the current OEE and its maximum potential is the current cost of
non-conformity. Sometimes called the ‘hidden factory’.
Operational Improvements: Improvement activities which result in increasing
