CFI Glossary: J-Q
JCAHO: Joint Commission for Accreditation of Healthcare Organizations
JIT: Just-In-Time – used to describe a manufacturing or other process in which materials arrive as close as possible to the time required
KPI: Key Performance Indicator – metrics that indicate performance to high priority objectives
Major Vertical Penetrations: Major vertical penetrations includes stairs, elevator shafts, utility tunnels, flues, pipe shafts, vertical ducts and their enclosing walls.
Mean: See definition for average. Mean and average are used interchangeably, and the interpretation is the same.
Median: The middle value in a range of responses is the median. One?half of all respondents will be below this value, while one?half will have a higher value. The median also is known as the 50th percentile. The advantage in using the median is that it is not affected as much by extreme highs or lows in the range of values as is the case with the mean.
MES: Manufacturing Execution System – schedules, tracks, and manages production; helps manage manufacturing labor, quality assurance, and maintenance; collects data generated by factory automation systems and creates production histories.
Metrics: Objective means of measuring performance and effectiveness. Often called Key Performance Indicator (KPI).
MIMOSA: Machinery Information Management Open Systems Alliance: An organization directed to facilitating the development of open exchange of equipment condition, maintenance and lifetime management information.
MTBE: Mean Time Between Events: Defined event used by some organizations to replace failures in reliability calculations (e.g., Mean Time Between Events)
MTBF: Mean Time Between Failure
MTBR: Mean Time Between Repairs
MTTR: Mean Time To Repair
Multi-Use: Used in a report to describe facilities with two or more primary uses, such as a single site that encompasses headquarter offices as well as production or research facilities.
MRO: Maintenance, Repair, Overhaul
NPV: Net Present Value: The current value of future revenue based on the time value of money
O&M: Operations and Maintenance
OEAM: Operating Equipment Asset Management: A comprehensive, fully integrated strategy, process and culture to gain greatest lifetime effectiveness, value, profitability and return from production and manufacturing equipment assets.
OEE: Overall Equipment Effectiveness: A term from Total Productive Maintenance that represents actual output compared to objective calculated from normalized Availability, Yield and Quality.
OEM: Original Equipment Manufacturer
Office Plans:
- Private offices – Enclosed by floor-to-ceiling walls.
- Open plan offices – Spaces divided by movable partitions.
- Bullpen style – Open areas with no partitions.
Open System: Systems from multiple suppliers that are capable of electronic communication (connectivity) and information exchange (interoperability) through published conventions without any proprietary or system-specific links
PdM: Predictive Maintenance: Also Condition Based Maintenance
Percentile: Indicates dispersion of data and a specific percentile identifies where a value lies in relation to other values in’ a range of responses. The 25th percentile is the lower one?fourth point in the range of values in the group. The 50th percentile, also referred to as the median, represents a value of which one?half of the group falls below and one?half falls above. The median is not affected by extreme high or low values whereas the mean could be distorted.
PM: Preventive Maintenance
Post Occupancy Evaluation: A survey taken after project completion to assess end users’ level of satisfaction with the various aspects of the new working environment, as well as to check on the performance against specifications of the major systems (Cotts 1999.)
Proactive Maintenance: Activities and actions applied to equipment prior to and during operation to prevent problems, gain greatest reliability, and minimize failure.
Preventive Maintenance (PM): Maintenance tasks to avoid failure—including inspection, service and/or replacement—conducted at regular, scheduled intervals based on average statistical/anticipated lifetime.
Primary Circulation: The portion of a building that is a public corridor or lobby. It is further defined as space required for access by all occupants on a floor to stairs, elevators, restrooms and building entrances or tenant space entry points on multi-tenant floors.
Prognostics: The ability to predict or forecast the future condition of a component, or system of components, in terms of either failure or degraded condition, so that it can satisfactorily conform to operational requirements (MFPG Forum, September 1999).
Project Management: Project management is the process of planning, organizing and managing tasks and resources to accomplish a well-defined objective, usually within constraints on time, resources or cost.
