Specialist (rank)
U.S. Army
Trades and specialties (1902–1920)
In 1920, the Army rank and pay system received a major overhaul. All enlisted and non-commissioned ranks were reduced from 128 different insignias and several pay grades to only seven rank insignias and seven pay grades, which were numbered in seniority from seventh grade (lowest) to first grade (highest). The second grade had two rank titles: first sergeant, which was three stripes, two rockers, and a lozenge (diamond) in the middle; and technical sergeant, which was three stripes and two rockers. By World War II, the rank of first sergeant had been elevated to first grade and a third rocker was added, with the lozenge in the center to distinguish it from master sergeant. The wearing of specialist badges inset in rank insignia was abolished, and a generic system of chevrons and arcs replaced them.
Statistical process control
The application of statistical techniques to control a process. The term "statistical quality control" is often used interchangeably with "statistical process control."
SPC
Storm Prediction Center. A national forecast center in Norman, Oklahoma, which is part of
NCEP . The SPC is responsible for providing short-term forecast guidance for severe
convection , excessive rainfall (flash flooding) and severe winter weather over the contiguous United States.
Statistical Process Control (SPC)
The term Statistical Process Control (SPC) is typically used in context of manufacturing processes (although it may also pertain to services and other activities), and it denotes statistical methods used to monitor and improve the quality of the respective operations. By gathering information about the various stages of the process and performing statistical analysis on that information, the SPC engineer is able to take necessary action (often preventive) to ensure that the overall process stays in-control and to allow the product to meet all desired specifications. SPC involves monitoring processes, identifying problem areas, recommending methods to reduce variation and verifying that they work, optimizing the process, assessing the reliability of parts, and other analytic operations. SPC uses such basic statistical quality control methods as quality control charts (Sheward, Pareto, and others), capability analysis, gage repeatability/reproducibility analysis, and reliability analysis. However, also specialized experimental methods (
DOE ) and other advanced statistical techniques are often part of global SPC systems. Important components of effective, modern SPC systems are real-time access to data and facilities to document and respond to incoming QC data on-line, efficient central QC
data warehousing , and
groupware facilities allowing QC engineers to share data and reports (see also
Enterprise SPC ).
