Definition
Work orders generated for changes to be made to the system during or after initial production and fielding.
General/Information/Narrative
Modification is any alteration, conversion, or modernization of an end item or component of an end item, which in any way changes or improves the original purpose or operational capacity in relation to effectiveness, efficiency, reliability, or safety of that item. This includes, but is not limited to: conversions, field fixes, retrofits, remanufactures, redesigns, upgrades, extended service programs, engineering changes, software revisions, system enhancement programs, service life extension programs, system improvement programs, product improvement programs, preplanned product improvements, modifications developed and applied by contractors as part of a prime vendor support (PVS) or contractor logistics support (CLS) agreements, horizontal technology integration (HTI), continuous technology refreshments (CTR), technology insertions, and all other terms used to describe modifications.
If a system is out of production and fielded (DD Form 250 has been signed), modifications will be applied using the MWO process. All ECPs must be developed into an MWO for application to these systems. If an item is to be modified using CTR, the guidelines, as set forth in paragraph 3–6, AR 750-10, govern its integration.
When the MATDEV convenes a Configuration Control Board (CCB) to review the modification and it is approved, the LCMC MWO coordinator will assign a materiel change number (MCN). The CCB decision will then be the authorization for the publication control officer to assign a valid MWO number. Both the materiel change and MWO numbers will be recorded in the MMIS and the MATDEV’s MWO database.
