LESSONS LEARNED
A phrase coined by Joseph Juran to describe a structured approach
to analyzing past experience in an endeavor  and applying the results
of that analysis to improving the quality of future efforts.

LEV
LOW EMISSION VEHICLES

LEVELING
The ability of a plating solution to produce a smooth and luster deposit with a lower surface roughness than the original substrate.

LFG
LANDFILL GAS

LFM
LINEAR FEET PER MINUTE

LFW
LINEAR FRICTION WELDING

LIMITING CURRENT DENSITY
The maximum current density at which satisfactory deposit can be obtained. The current at which the anode
dissolves normally without excess polarization.

LINE GRAPH
This graph is another way to visually display data for purposes of comparison.
Specific items are entered by number  and the data points are then connected
by a line.  Lines make trends and data variations over time easy to track.
An excellent tool for highlighting change.  Can be used for more than one set of data at a time.
