LORA process during the acquisition life cycle. The LORA process involves a group of three
systematic and comprehensive evaluations (i.e., economic, noneconomic, and sensitivity evaluations), that when
conducted on an iterative basis throughout all phases of the system/equipment life cycle, arrive at level of
repair/discard alternatives that satisfy sustainment objectives. Through these iterative evaluation processes, a
maintenance and support concept for the system/equipment which is effective, yet economical, can be established.
This is often accomplished by influencing the system's design for supportability. The LORA process should
integrate design, operations, performance, cost, readiness, and product support characteristics to assist in identifying
and refining the maintenance and support concept for the system/equipment. The level of detail and timing of the
analyses and activities to be performed should be tailored to each system/equipment. These factors will be
responsive to program schedules, milestones, risks, and the ability to influence the system design.
