MBSE Infusion Questions § How do you measure infusion progress? – Number of programs using MBSE as a mechanism for performing SE functions § What is the nature of the organization for which your are infusing MBSE – Each business unit within Raytheon has its own MBSE initiatives, but we are working to leverage efforts across business units and implement a companywide strategy – MBSE focuses mostly on SE and SW at the moment, but we have other activities in other disciplines that we are working to coordinate (such as mechanical design, electrical design, manufacturing, etc) – Product range from weapon systems, sensors, radars, command control systems, Cyber Systems, etc… – Primary customers are U. S. government agencies, with an expanding presence in international military and commercial markets. Work concentrates on the full lifecycle from concept definition through sustainment. 2/28/2021 2

MBSE Infusion Questions § What enablers and barriers in your environment – Enablers: corporate cross-business unit collaboration mechanisms, vendor relationships (e. g. , IBM), internal funding mechanism – Barriers: § “not the way we do business”, § “show me the ROI”, § "fear of receiving Do. DAF instead of specifications“, § early experiences with immature tool sets, non-integrated tool sets, § lack of modeling competencies, § difficulty in integrating MBE techniques into long running legacy programs, § the need to fund MBE activities "up front" with value that's realized late in the program or on later efforts, § difficulty in reusing modeled resources from one discipline or activity in the next steps. – Biggest barrier is our own ability to clearly make the business case § What primary MBSE value do you communicate to for your stakeholders to obtain their involvement/commitment. Do you try to measure this value? – Reduced cycle time, reduced development cost, – reduced rework (especially during integration & test) due to early identification of errors and disconnects due to better communications (customer and cross-team) and more effective analysis of alternatives, – potential for increased re-use – We have not been successful in measuring this value 2/28/2021 3
