Olivier has an extensive background in electronics, with a special focus on microprocessors. Olivier moved to model-based development more than thirty years ago, first for software engineering, then for systems engineering. He has supported clients in developing rigorous specifications for major rail, automotive, aerospace/defense, medical, and embedded systems projects. During his long career in model-based development, Olivier has had the opportunity to work for several of the companies that have produced top model-based development tools. This experience has given him a nuanced understanding of the strengths and weaknesses of each tool, as well as a strong understanding of where users run into difficulties understanding the tools and the modeling languages. He spends much of his time teaching the top SysML tools as well as teaching the Arcadia method and the open source Capella tool that supports it. He also coaches clients in developing their in-house tool methodologies, creates animated training materials, and serves as a mentor to senior product architects. He draws on his deep model-based development experience to help clients develop language and tools best practices all the way through the systems engineering "V" cycle - from the initial concept to field deployment and disposal. Olivier is a frequent conference speaker and serves clients worldwide - Europe, North America, Asia, and Australia. He lives near Paris.
