Life cycle. A generic term covering all phases of acquisition,
operation, and logistics support of an item, beginning with concept definition
and continuing through disposal of the item.
Life cycle cost. The total cost to the Government of acquisition and
ownership of that system over its life cycle. It includes the cost of
development, acquisition, support, and where applicable, disposal.
Manufacturer's code. See "Commercial and Government Entity (CAGE) code".
Materiel. A generic term covering systems, equipment, stores, supplies,
and spares, including related documentation, manuals, computer hardware, and
Non-conformance. The failure of a unit or product to conform to
Non-developmental item is a broad generic term that covers material available
from a wide variety of sources with little or no development effort required by
the Government. NDIs include:
a. Items obtained from a domestic or
foreign commercial marketplace.
b. Items already developed and in use by
the Services, other Defense activities, and Government agencies.
already developed by foreign governments which can be supplied in accordance
with mutual defense cooperation agreements and Federal and DoD acquisition
Non-recurring costs. As applied to ECPs, these are one time costs, which
will be incurred if an engineering change is approved and which are independent
of the quantity of items changed, such as cost of redesign, special tooling, or
Notice of Revision (NOR). A document used to define revisions to
drawings, associated lists, or other referenced documents which require revision
after Engineering Change Proposal approval.
Original. The current design activity document or digital data file(s)
Physical characteristics. Quantitative and qualitative expressions of
material features, such as composition, dimensions, finishes, form, fit, and
their respective tolerances.
Physical Configuration Audit (PCA). The formal examination of the
"as-built" configuration of a configuration item against its technical
documentation to establish or verify the configuration item's product baseline.
Product Baseline (PBL). The initially approved documentatiOn describing
all of the necessary functional and physical characteristics of the
configuration item and the selected functional and physical characteristics
designated for production acceptance testing and tests necessary for support of
the configuration item. In addition to this documentation, the product baseline
of a configuration item may consist of the actual equipment and software.
Product Configuration Documentation
(PCD). The approved product baseline
plus approved changes.
Release. The designation by the contractor that a document is complete
and suitable for use. Release means that the document is subject to the
contractor's configuration control procedures.
Repair. See MIL-STD-1520.
Replacement item. See MIL-STD-280.
Retrofit. The incorporation of new design parts resulting from an
approved engineering change to an item's current approved product configuration
documentation into already accepted and/or operational items.
Rework. See MIL-STD-1520.
Software. See "Computer software" in DoD-STD-2167.
Specification. See MIL-STD-961.
A document used to propose, transmit, and record changes to a specification.
Substitute item. See MIL-STD-280.
Support equipment. Equipment and computer software required to maintain,
test, or operate an item or facility in its intended environment.
Survivability. The capability of a system to avoid or withstand a
hostile environment without suffering an abortive impairment of its ability to
accomplish its designated mission.
System. See MIL-STD-280.
Technical data is recorded information (regardless of the form or method
of recording) of a scientific or technical nature (including computer software
documentation) relating to supplies procured by an agency. Technical data does
not include computer software or financial, administrative, cost or pricing, or
management data or other information incidental to contract
a. Technical data is required to define and document an
engineering design or product configuration (sufficient to allow duplication of
the original items) and is used to support production, engineering, and
b. A technical data package should include all
engineering drawings, associated lists, process descriptions, and other
documents which define the physical geometry, material composition, performance
characteristics, manufacture, assembly, and acceptance test
c. Technical data which provides instructions for the
installation, operation, maintenance, training, and support of a system or
equipment can be formatted into a technical manual.
(1) A technical
manual normally includes operation and maintenance instructions, parts lists or
parts breakdown, and related technical information or procedures exclusive of
(2) This data may be presented in any form
(e.g., hard copy, audio and visual displays, magnetic tape, disks, or other
(3) Technical orders that meet the criteria of this
definition may also be classified as technical manuals. (Title 10, United States
Code, Section 2302, "Definitions")
Technical data package. See "Technical data".
Technical documentation. See "Technical data".
Technical reviews. A series of system engineering
activities by which the technical progress on a project is assessed relative to
its technical or contractual requirements. The reviews are conducted at logical
transition points in the development effort to identify and correct problems
resulting from the work completed thus far before the problems can disrupt or
delay the technical progress. The reviews provide a method for the contractor
and Government to determine that the development of a configuration item and its
documentation have met contract requirements.
All types of maintenance and operator training hardware, devices, audio-visual
training aids, and related software which:
a. Are used to train
maintenance and operator personnel by depicting, simulating, or portraying the
operational or maintenance characteristics of an item or facility.
b. Are kept consistent
in design, construction, and configuration with such items in order to
provide required training capability.
Unit. See MIL-STD-280.
Version. An identified and documented body of software. Modifications to
a version of software (resulting in a new version) require configuration
management actions by either the contractor, the Government, or both.
Waiver. A written authorization to accept an item, which during
manufacture, or after having been submitted for Government inspection or
acceptance, is found to depart from specified requirements, but nevertheless is
considered suitable for use "as is" or after repair by an approved method.
