A CSI is any ship part, assembly, or support equipment containing a critical characteristic whose failure, malfunction, or absence may cause a catastrophic or critical failure resulting in loss or serious damage to the ship, or unacceptable risk of personal injury or loss of life. This instruction defines associated CSI terminology for use in supporting processes by various commands and organizations involved in this program. It also addresses requirements governing the initial determination of item criticality (and subsequent changes in determination), unique coding for visibility of items so designated, and the supplier evaluation and qualification processes supporting procurement and refurbishment of CSIs. Minimum requirements for life-cycle management of non-nuclear replenishment items meeting the definition of CSI are provided. Supplemental requirements are detailed for the generation of technical data packages and proposed changes in support of Configuration Management programs including the recognition of authority to act on waivers and deviations pertaining to CSIs.
