INEERING CHANGE PROPOSAL (ECP) – Army Materiel Command (AMC)
Number: DI-CMAN-81589 Approval Date: 5 October 2000
AMSC Number: A7404 Limitation: None
DTIC Applicable: No GIDEP Applicable: No
Office of Primary Responsibility: AM
Applicable Forms: N/A
Use, Relationships: An Engineering Change Proposal (ECP) provides the documentation in which the engineering change is
described. It includes change impacts to systems, configuration items and associated configuration documentation that are
affected by the proposed change. In addition, it typically describes how the proposed change will be implemented along with
providing estimated schedules and associated costs.
This Data Item Description (DID) contains the content and preparation instructions for the data product resulting from the
work task specified in the contract. This DID is used in conjunction with a Notice of Revision (NOR). A requirement for
NORs, as applicable, should be contractually imposed in conjunction with this DID.
Requirements:
1. R
eference documents.
The applicable issue of any documents cited herein, including their approval dates and dates of
any applicable amendments, notices, and revisions, shall be as specified in the contract.
2. Format and content.
The Engineering Change Proposal shall be prepared in contractor format. The ECP content shall be
in accordance with the contractor’s processes and procedures.
3. Supporting data
. In addition to the information required below, the ECP shall include supporting data. Formal ECPs
shall be supported by drawings and other data (e.g., LSA data, detailed cost proposal data, test data and analyses) as
specified in the contract to justify and describe the change and to determine its total impact including assessments of
changes to system operational employment characteristics. 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 the change into all future production and spare items projected to be procured for the program. Also for all proj
ected
operation and support costs for operation of the total inventory of items by the Government. A summary of any testing
done to validate concepts or new technology to be employed in the proposed engineering change shall be presented in
the supporting data. Details of such test data shall be provided if it is vital to the decision regarding acceptance of th
e
change.
4.
Dis
tribution statement
. The appropriate distribution statement shall be affixed to the ECP in accordance with the
requirements of the contract.
5. Date
. Provide the submittal date of the ECP or of the revision to the ECP.
6. Procuring Activity Number (PAN)
: Provide the PAN of the procuring activity, if known (Army only).
7. DODAAC
. Provide the DODAAC of the procuring activity, if known.
8. Originator name and address
. Provide the name and address of the contractor submitting the ECP.
9. Designate as either Class I or II
. Proposed changes that do not meet the criteria for Class I shall be designated as Class II.
The engineering change shall be Class I if:
a. The Functional Configuration Documentation (FCD) or Allocated Configuration Documentation (ACD) is affected
to the extent that any of the following requirements would be outside specified limits or specified toleran
ces:
(1) Performance.
(2) Reliability, maintainability or survivability.
(3) Weight, balance, moment of inertia.
