The basis for validation is a set of requirements that provide the success criteria for a system or system element. The mission requirements are provided in the Mission Requirements Document (MRD), an applicable document. |
|
| Variance |
|
An authorization for temporary relief in advance from a specific requirement and is requested during the formulation/planning/design stages of a program/project operation to address expected situations. |
|
| Verification |
|
The process of determining that the deliverable item meets specified requirements, using methods such as test, demonstration, analysis, and inspection. |
|
| Verification Basis |
|
The basis of verification is a description and definition, for each requirement, of the method used to verify that requirement has been achieved, e.g. by test, analysis, design, inspection and/or a combination of methods. |
|
| Verification by Analysis |
|
The use of mathematical models and analytical techniques to predict the suitability of design and compliance with a requirement, when the subject item is not available or suitable for testing. |
|
| Verification by Demonstration |
|
The observation of an item in use under specific, controlled conditions in order to determine if it satisfies a requirement, without the detailed data collection and analysis that is part of testing. |
|
| Verification by Inspection |
|
The visual examination of a item in order to determine if it satisfies a requirement. |
|
| Verification by Test |
|
The use of an item under specific, controlled conditions in order to obtain detailed data and/or information that can be evaluated to determine if the item satisfies a requirement. |
