All rights reserved. 6/11/2015 Raytheon’s Pre-COTS Process System View The results were highly capable systems, uniquely optimized; some are still around Operational View Significant engineering effort expended in operations analysis, acquiring domain expertise by hiring, training, and practice. Analysis and modeling tools used extensively Technical View Components and subsystems are designed and implemented specifically for unique sets of requirements. Significant reuse of software and architecture within narrow domain But software is always modified to fit operational needs Prior to the widespread availability of reliable COTS components and architecture frameworks, the operations view and concepts drove Raytheon’s architecture strategy. -Operational needs defined requirements -Requirements determined architecture and design -Design got implemented from scratch or modification of similar domain specific component Operational Architecture Proprietary Technical Architecture System Architecture...

All rights reserved. 6/11/2015 Transitioning to a COTS Architecture Process System View Many systems have successfully incorporated some COTS by: -significant work behind the scenes to make things fit -forcing the operations to fit the general model. Neither method makes the best use of the architecture-based approach Operational View However, the advent of COTS disintegrated the linear, closely coupled relationship between the operations view and the technical Generalized capabilities often do not fit domain specific operational needs well Technical View Increasing effort devoted to working- around “features” of COTS. The ball peen hammer approach to integration Drive towards COTS, common, open architectures pushed by: -Increasing complexity, sizes, numbers; -The ongoing information technology revolution places extraordinary demands on systems. -Desire for more advanced features -Economics -Healthy competition Operational Architecture Common/COTS Technical Architecture System Architecture...

All rights reserved. 6/11/2015 Research Opportunities n Raytheon is committed to the architecture based development strategy and to the use of COTS architectures and components n We see continuing challenges in matching general-purpose COTS to the operational imperatives of our domain specific products n Refinement of techniques for mapping operational requirements to architecture solutions will be highly beneficial, for example — Refinement of existing Software Quality Engineering Methods — Development of new, situational, operational-context-based modeling techniques

All rights reserved. 6/11/2015 Situational Logic and Modeling n Situational logic is a fairly recent extension to logic that provides means to model and operate processes in context n The research objective is to develop means to employ situational knowledge and context information in reasoning about architecture alternatives n Situational, i.e., contextual models may provide: — Means to incorporate operational view into effective system models earlier in the development lifecycle — Such operational models could draw attention to the environmental or processing features that impact COTS selection — This would provide the means to measure qualitative distances between operational and technical solution spaces n Note “Situation” has high relevance in Raytheon C3I systems: — Situation Display, Situational Awareness are key operational concepts — Changes in situation, rather than mode or state, tend to be the performance drivers and suitability
