- S Curve
-
  A display of cumulative costs, labor hours or other quantities plotted against time.
Editor's Note: The name derives from the S-like shape of the curve, flatter at the beginning and end and steeper in the middle, which is typical of most activities (and whole project). The beginning represents a slow, deliberate but accelerating start, while the end represents a deceleration as the work runs out. [D01832]

CPMUSC 176-8 |
- A graphic display of cumulative costs, hours, percentage of work, or other items, plotted over a horizontal time scale, often used to track cost performance for management. Such curves start slowly, accelerate in the middle, and then taper off slowly at the end. The "S" curve is considered to be normal distribution for such work, and essentially reflects the classic "bell" distribution curve. [D06249]

USDoD
QMPP |
- Sampling Plan
- A statement of the sample size or sizes to be used and the associated acceptance and rejection criteria. [D01764]
|
MIL-STD 109A
QMPP |
- Sampling Plan, double
- A specific type of attributes sampling plan in which the inspection of the first sample leads to a decision to accept, to reject, or to take a second sample. The inspection of a second sample, when required, then leads to a decision to accept or reject. [D01765]
|
MIL-STD 105
QMPP |
- Sampling Plan, multi-level
- Continuous. A specific type of sampling plan in which the inspection periods of 100 percent inspection and two or more levels of sampling inspection are alternated with the sampling frequency remaining constant or changing on the basis of the inspection result. [D01766]
|
USDoD
QMPP |
- Sampling Plan, sequential
- A specific type of sampling plan in which the sample units are selected one at a time. After each unit is inspected, the decision is made to accept, reject, or continue inspection until the acceptance or rejection criteria is met. Sampling terminates when the inspection results of the sample units determine that the acceptance or rejection decision can be made. The sample size is not fixed in advance, but depends on actual inspection results. [D01767]

QMPP |
- Sampling Plan, single
- A specific type of sampling plan in which a decision to accept or reject an inspection lot is based on a single sample. [D01768]
|
MIL-STD 105
QMPP |
- Sampling Plan, single-level
- Continuous) A specific type of sampling plan in which the inspection periods of 100 percent inspection and sampling inspection are alternated with the sampling rate remaining constant. [D01769]
