| Term | Definition |
|---|---|
| Valid Requirements |
Procedures, specifications, plans or policies which meet the needs of the customer(s) and are current, realistic, understandable, measurable, achievable and compatible with other requirements. When conformed to, valid requirements yield quality. |
| Value Added |
Activities or work essential to ensure a product or service meets the needs of the customer. |
| Value engineering |
a total approach to design that achieves improved performance and quality by stressing simplicity and integration of design and manufacturing techniques. |
| Values |
Principles or qualities which are worthwhile and govern the operation of total quality management. |
| VAR |
a Value-Added Reseller. |
| Variable |
A factor that can be altered, measured, or controlled. |
| Variable data |
Numerical information that can be changed during application operation. It includes timer and counter accumulated values, thumbwheel settings, and arithmetic results. |
| Variation |
Periodic or sporadic changes or deviations within a process. |
| Varistor |
A two-electrode semiconductor device with a voltage-dependant non-linear resistance that drops markedly as the applied voltage is increased. It is used to suppress transient voltage surges. |
| VBA |
Visual basic for applications |
| VDT |
Video Display Terminal. |
| Vector |
A quantity that denotes both magnitude and direction. Vectors are commonly represented by a line segment with an arrow; the length represents the magnitude; the orientation in space and the placement of the arrow at one end of the line represents the direction. |
| Vector quantity |
A quantity that denotes both magnitude and direction in relation to a given frame of reference. Examples of quantities that are vectors are displacement, velocity, force, and magnetic intensity. |
| Velocity |
A vector quantity that denotes both magnitude (e.g., speed) and direction in relation to a given frame of reference. |
| Velocity loop |
A feedback control loop in which the controlled parameter is motor velocity. Usually uses a tachometer for a feedback device. |
