Glossary of TPM terms

Asset Care Programme: A systematic approach to keeping equipment in ’as
new’ condition. This consists of carrying out routine activities such as: cleaning
and inspection (carried out by the operator and sometimes called Operator
Asset Care or Autonomous Maintenance), checking and monitoring (sometimes
called Condition Based Monitoring), preventative maintenance and servicing
(sometimes called Maintainer Asset Care).
Availability: The actual run time of a machine as a percentage of its planned
run time.
Best of the Best: An OEE figure calculated by multiplying the best weekly
availability, the best weekly performance and the best weekly quality rates
for a machine over a period, e.g. of typically one month.
CAN D0/5S: Five common sense principles of workplace organization
(arrangement, neatness, cleaning, order and discipline). CAN DO is the western
equivalent of the Japanese 5Ss.
Condition Appraisal: The assessment of the condition of a machine’s
components as a first step to undertaking the refurbishment plan and improving
the OEE. This must involve carrying out a deep clean as part of the assessment.
Condition Cycle: The second stage of the TPM Improvement Plan, which
includes criticality assessment, condition appraisal, refurbishment plan and
the asset care programme.
Core Team: These are the mixed shift based teams comprising operators and
maintainers and a Team leader. These teams work through the 9 Step TPM
Improvement Plan on their Pilot Projects typically over a 12 to 16 week
period.
Criticality Assessment: An evaluation of each of the machine’s components
against set criteria and their likely impact on production, safety, environment
and cost.
Five Whys: Asking ‘Why?‘ five times to try to get to the root cause of the
problem.
Four Milestones: This is the progression the organization goes through over
a period of approximately 4-6 years as they embark on the TPM Process.
These have been recognized as discrete phases that organizations go through
as they transform themselves. The 4 Milestones are:

1. Introduction
2. Refine Best Practice and Standardize
3. Build Capability
4. Zero Losses
