Pareto – An analysis to determine the minority of equipment that is
causing the majority of the problems. Also known as the 80/20 rule.
Process Flow – A method of visually documenting the stages involved
in performing a certain business procedure
Process Parameters – Are certain measures that refer to status of the
process. In order to obtain effective execution of the process its
parameters should stay under continuous control.
Process Variation – Is the statistical description of natural fluctuations
in process outputs.
Specifications – Physical, chemical, or performance characteristics of
equipment, parts, or work required to meet minimum acceptable
standards
Standard Operating Procedures – Is a set of step-by-step instructions
compiled by an organization to help workers carry out complex
routine operations. SOPs aim to achieve efficiency, quality output and
uniformity of performance, while reducing miscommunication and
failure to comply with industry regulations.
Statistical Process Control – A method of monitoring, controlling and
improving a process through statistical analysis. Its four basic steps
include measuring the process, eliminating variances in the process to
make it consistent, monitoring the process and improving the process
to its best target value.
Total Productive Maintenance (TPM) – Companywide equipment
management program emphasizing operator involvement in
equipment maintenance and continuous improvement in equipment
effectiveness
Value Stream Mapping – Is a lean-management method for analyzing
the current state and designing a future state for the series of events
that take a product or service from its beginning through to the
customer.
Equipment Reliability
Asset Criticality – A measure of the importance of an asset relative to
other assets
Availability (A) – The probability that an asset is capable of performing
its intended function satisfactorily, when needed, in a stated
environment. Availability is a function of reliability and maintainability.
Breakdown Maintenance – A policy whereby no maintenance is done
unless and until an item no longer meets its functional standard, often
when the asset is no longer able to operate
Condition Based Maintenance (CBM) – Repair or restoration of an
asset based on its condition at the time; also known as on-condition
maintenance
Condition Monitoring – The monitoring of equipment performance or
other condition parameters to determine the condition or health of
the equipment or system. Condition-based monitoring is used as part
of a predictive maintenance program to determine the need for
condition-based maintenance.
Failure – Failure is the inability of an asset component to meet its
expected performance. It does not require the asset to be inoperable.
The failure could also mean reduced speed, or not meeting
operational or quality requirements.
Failure Cause – Are defects in design, process, quality, or part
application, which are the underlying cause of a failure or which
initiate a process which leads to failure.
