About this file
This document contains two parts: an attachment analyzing the failure modes and effects of a media converter component through a Failure Modes, Effects and Criticality Analysis (FMECA), and a draft Request for Proposal (RFP) for the Integrated Battle Command System (IBCS) Low Rate Initial Production/Full Rate Production (LRIP/FRP) hardware segment.
The FMECA attachment analyzes four potential failure modes for a media converter component used in an E069 shelter: does not operate, intermittent operation, degraded functional operation, and no failures. It assigns severity classifications and calculates failure rates both with and without considering redundant emergency operation centers (EOCs).
The draft RFP seeks hardware production for IBCS, including maintaining approved software/firmware updates and authority to operate on existing hardware. Engineering changes may be required for obsolescence, new capabilities, and export considerations. The RFP is from the Department of the Army Materiel Command Contracting Command at Redstone Arsenal for an unspecified dollar value and period of performance. No response is currently being solicited as this is a draft for comment only.
