Justification codes corresponding with the criteria
necessary for beneficial engineering changes are listed below. If more than
one of these codes are applicable, the one which is the most descriptive or
significant shall be assigned to the ECP.
a. Interface (Code
B). Code B shall be assigned to an engineering change proposed to eliminate
incompatibility between CIs.
b. Compatibility (Code C). Code C shall be assigned to an engineering change
to correct a deficiency with the following characteristics:
(1) The need for the change has been discovered during the system or item
functional checks or during installation and checkout and is necessary to make
the system or item work.
(2) By assigning the compatibility code the contractor is declaring that the
effort required to accomplish the change is considered to be within the scope of
the existing contract except for changes caused by the Government.
(3) Contractual coverage completing the formal documentation of the
engineering change will not reflect an increase in contract price for the
corrective action in production and to delivered items in-warranty or otherwise
stipulated in the contract.
c. Correction of deficiency (Code D). Code D shall be assigned to an
engineering change which is required to eliminate a deficiency, unless a more
descriptive separate code applies. Such separate codes are used to identify
deficiencies of the nature of safety, interface, or compatibility.
d. Operational or logistics support (Code O). Code O shall be assigned to an
engineering change which will make a significant effectiveness change in
operational capabilities or logistics support.
e. Production stoppage (Code P). Code P shall be assigned to an engineering
change which is required to prevent slippage in an approved production schedule.
This code applies when production to the current configuration documentation
either is impracticable or cannot be accomplished without delay.
f. Cost reduction (Code R). Code R shall be assigned to an engineering change
which will provide a net total life cycle cost savings to the Government, but
which is not being submitted pursuant to the Value Engineering clause of the
contract. The savings in life cycle cost should include all effects on cost and
price for the effort and requirements covered by the contract(s) currently in
effect for this contractor, plus the costs resulting from necessary associated
changes in delivered items, logistics support, and in items produced by others.
When a life cycle cost and/or operation and support cost model has been included
in the contract, the ECP shall also include the costs expected to result from
the implementation of this change into all future production and spare items
projected to be procured for the program and all projected operation and support
costs for operation of the total inventory of items by the Government.
g. Safety (Code S). Code S shall be assigned to an engineering change for
correction of a deficiency which is required primarily to eliminate a hazardous
condition. When this code is assigned, a system hazard analysis per MIL-STD-882
shall be included with the ECP.
h. Value engineering (VE) (Code V). Code V shall be assigned to an
engineering change which will effect a net life cycle cost reduction and which
is submitted pursuant to the VE clause of the contract.
