AADL/ACVIP User Days 2021 was hosted by the Software Engineering Institute (SEI) and held virtually on February 3-4, 2021. AADL/ACVIP User Days is a free two-day virtual forum to present the latest on the Architecture Analysis and Design Language (AADL), the Architecture-Centric Virtual Integration Process (ACVIP), and associated tools.

This presentation by Garrett Thurston was given virtually at AADL/ACVIP User Days 2021. Frequently the concept of ACVIP is discussed in the context of system-level timing concerns at the architecture level. This presentation will discuss the phase-gate evolution of timing analysis and scheduleability early in the lifecycle at the architecture level and then we will take some time to dive into conducting the same kind of analysis, again-pre-implementation but at the design level. In this later case, many design decisions of the integrated compute topology elements of the aircraft, weapons system or system of systems have been determined. It is important to contain technical debt by again analyzing that the design-level AADL-enabled ACVIP analysis demonstrate consistency with the architecture or resolve any inconsistencies. I will also briefly touch upon scheduleability concepts of acquisition and modular open system approaches temporal statutory aspects including concerns outlined in DoDI 5000.88.

Dr. Garrett Thurston has worked in the aerospace and defense sectors for 35 years, working on and managing Air Force, ONR, DARPA, DoE, and NASA programs, including collaborations with national labs. His current areas of work include large-scale digital transformation, mission-forward innovation, model-based acquisition, platform families, product lines, and modular open systems approaches. Garrett's initial thinking precipitated Dassault Systemes' acquisition of No Magic, a global solutions company focused on model-based systems engineering and architecture modeling for software and system of systems.

In addition, Garrett has worked on transforming the way that model-based digital transformation is engaged and conducted at the extended enterprise level; evolving a legacy consulting approach of spreadsheets and PowerPoint to true model-based systems engineering (MBSE) approaches, utilizing Unified Architecture Framework (UAF) constructs, mapping strategic and business architecture transformation challenges to business solution architecture transitional elements. Garrett has also conducted extensive work in developing value-based methods of assessment as a means of charting roadmaps, plans, and execution.
