MIL-HDBK-1390
5.7.2.4 P&D/O&S phases. In the P&D and O&S phases, the design is fixed and there are limited
opportunities for tradeoffs or further optimization of the design. A LORA may be applicable if unanticipated
circumstances arise that require design changes be made to the system/equipment. A LORA may also be conducted
for update purposes to adjust LORA decisions based on field experience or evaluations on ECPs and PIPs.

5.7.3 Previously performed analyses. Previously conducted analyses can impact LORA activity selection.
These analyses may include other LORAs, PSAs, and other related systems engineering analyses, or work already
accomplished. The previous work should be assessed for accuracy, reliability, and operational similarities and
differences. If the documented results of the previous work are adequate, the analysis may only require updating as
opposed to conducting a new analysis. Program documents may also prescribe objectives or constraints which tend
to bind the scope of the LORA effort.
Decision making. Since LORAs are performed iteratively, the final analysis should verify the results
5.8
of the earlier analyses or recommend a change based upon finalized input data. The LORA and associated results
will be used to influence the repair or discard decisions made on materiel, and these decisions will, in turn, provide
repair or discard recommendations to the equipment designer. Also, the LORA provides input to the procuring
activity so that proper IPS decisions may be reached. Implementation of the LORA decisions should allow for the
proper funding, scheduling, and deployment of the necessary/required support resources to meet operational
readiness objectives. The goal is that those resources may be in place for the system or equipment when fielded.
