A check sheet is a form (document) used to collect data in real time at the location where the data is generated. The data it captures can be quantitative or qualitative. When the information is quantitative, the check sheet is sometimes called a tally sheet. [1] The check sheet is one of the so-called Seven Basic Tools of Quality Control. [2]
Most often a producer supplies a consumer with several items and a decision to accept or reject the items is made by determining the number of defective items in a sample from the lot. The lot is accepted if the number of defects falls below where the acceptance number or otherwise the lot is rejected.

A PMCS is required before a vehicle can be dispatched and before a piece of equipment, such as a weapon, can be issued. A PMCS sheet, as listed above, for vehicles is called a DA 5988E. This sheet is used to write down any deficiency found during the PMCS procedure. [2]
One technique is to fix sample size so that there is a 50% chance of detecting a process shift of a given amount (for example, from 1% defective to 5% defective). If δ is the size of the shift to detect, then the sample size should be set to n ≥ ( 3 δ ) 2 p ¯ ( 1 − p ¯ ) {\displaystyle n\geq \left({\frac {3}{\delta }}\right)^{2}{\bar {p ...
In process improvement efforts, defects per million opportunities or DPMO (or nonconformities per million opportunities (NPMO)) is a measure of process performance.It is defined as
Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system.It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again.
