adequately describe what is to be accomplished. It shall be phrased in
definitive language such that, if it is repeated in the contractual document
authorizing the change, it will provide the authorization desired. A
description as to which part of the item or system is being changed shall be
provided. Supplemental drawings and sketches shall be provided to the extent
necessary to clearly portray the proposed change. If the proposed change is an
interim solution, it shall be so stated. If additional space is needed, use
continuation pages for details but provide an overview in this block.

replacing the existing ECP in its entirety, or provides change pages to the
D.5.1.20 Block 20. Need for change. Enter an explanation of the need for
the change to include specifically identifying the benefit of the change to
the Government. The nature of the defect, failure, incident, malfunction, etc.
substantiating the need for the change-shall be described in detail. Full
utilization shall be made of available failure data. If a new capability is to
be provided, improvements in range, speed, performance, endurance, striking
power, defensive or offensive capabilities, etc. shall be described in
quantitative terms. Correspondence establishing requirements for the change
and any testing accomplished prior to the submission shall be identified and
summarized. If the ECP is needed to correct maintenance/ logistics problems,
that fact will be included with sufficient detail to identify the issues. If
the ECP is being submitted as a response to a request for ECP or Government
direction, cite that authority herein. Additional pages may be added as
D.5.1.21 Block 21. Production effectivity by serial number.
a. For hardware, enter the contractor's estimated production effectivity
point for the production items including serial number, or other item
identification (e.g., block or lot number) as approved by the Government. In
determining the effectivity point for the proposed change, the contractor
shall consider, in addition to the time factors, the availability of all
support elements affected and the most economical point of introduction
consistent with all the salient factors involved. The earliest production
incorporation is not necessarily the singular or most important factor in the
establishment of a proposed change effectivity point. The effectivity point
will be based on concurrent availability of all logistics support elements and
materials affected by the change to the item.
b. For CSCI's, identify the CSCI version number into which the change will
be incorporated. Where applicable, the effectivity of the end item CI and
vehicle (aircraft, tank, ship, etc.) into which the capability represented by
the new version of the software is proposed to be incorporated, shall also be
provided. If the impact of the ECP merits the release of a new software
version, Block 21 of the ECP submittal shall include a recommendation to this
effect. Serial numbers may be used in lieu of version numbers if approved by
D.5.1.22 Block 22. Effect on production delivery schedule. State the
estimated delivery schedule of items incorporating the change, either in terms
of days after contractual approval, or by specific dates contingent upon
contractual approval by a specified date. If there will be no effect on the
delivery schedule, so state. For a complex ECP, or for related ECPs, this
delivery date will be repeated on the milestone chart together with the
schedule for other interrelated actions.
D.5.1.23 Block 23. Retrofit.
D.184.108.40.206 Block 23a. Recommended item effectivity. When the contractor
recommends that the engineering change be accomplished in accepted items by
retrofit (see Block 43), the quantities and serial (or lot) numbers of
accepted items in which the change will be incorporated by retrofit shall be
entered in Block 23a, or in a referenced enclosure. Such statement regarding
items currently in production shall be based upon the estimated approval date
of the ECP.
