The output of this initial segment should be an integrated Operational Requirements Document (ORD) which reflects an operational and support concept that the user finds acceptable. Following this initial segment, the primary focus of supportability analyses should be on examining the user’s operational and readiness requirements using guidance provided in the Mission Needs Statement and the ORD.
The output of the Requirements Analysis segment should identify key issues or supportability “factors” that should be considered when operational needs are later translated into supportability requirements. Supportability factors are those operational needs which, by their nature, impose requirements on the support system and thus affect system supportability. Supportability factors may include deployment, mobility, mission frequency and duration, human capability and limitations, and anticipated service life.
During the Functional Analysis/Allocation (FA/A) segment, these factors and other operational needs which affect supportability should be analyzed to establish initial supportability constraints. Deployment Planned deployment scenarios establish the geographical and environmental conditions in which a system must be operated and sustained. Different operating environments impose different design characteristics on a product. These characteristics directly affect the types of support required and the environmental conditions under which the support must be provided.
For example, just as planned deployment to an arctic environment will require a product design which can function under conditions of extreme cold, maintenance and operational support activities such as repair or refueling will have to be performed under the same conditions. Product designs should reflect the operational need to perform support functions in environmentally suitable clothing (e.g., arctic clothing, chemical protective clothing, etc.). Mobility A unit’s mobility requirements establish planned modes of transport and time constraints which must be accommodated by the transportability characteristics of a product.
A product which is to be transported by specific modes of transport such as rail, sea, or air, and within each mode, by specific means (C130, C5A, European rail carriers, etc.) must be evaluated to ensure that it’s design characteristics allow transport by the planned mode or means. Time constraints, such as 24-hour rapid deployment, impose further considerations to ensure that the product can be prepared for transport within the established time. If, for example, a product must be sectionalized for transport by a designated means such as a C130 aircraft, then the product must be capable of sectionalization, and 5-3
