Operational Capability Advancement Through Open Architecture Application - Flipbook - Page 12
For the strategy to be successful, there needs
to be direction through a chain of authority
and a set of relationships that exists to
ensure that architecture management across
the enterprise is enabled. This includes
technical support to capability assessments
and decision-making at the top, which in
turn generates sets of requirements through
the organization to ensure that ultimately,
requirements are placed on the platform
programs, ensuring the programs deliver
systems that more effectively contribute to the
overarching mission capability.

Currently, there is too much assumption on extant systems at the capability assessment level without suf昀椀cient technical insight into the
art of the possible. The resulting technical requirements that drive the platform programs are formulated at the program level and are
not likely to consider a wider cooperative approach with pan-program consideration cognizant of the wider mission capability. Likewise,
it is for the programs to determine how they are going to achieve non-functional considerations such as assurance, accreditation,
con昀椀guration, and system architecture 昀氀exibility.
It is our position that OA expertise should be involved in the mission capability assessment and wargaming exercises. Experts who
understand the operational environment and have expertise in advanced systems engineering can help shape the acquisition strategy
and technical requirements at a high level in the enterprise. The resulting 昀氀eet of systems will be more robust, more collaborative, and
ultimately more effective – thus reducing operation risk to the war昀椀ghter and maximizing the chance of mission success.
