ATI's Fundamentals of COTS-Based Systems Engineering
Leveraging Commercial Off-the-Shelf Technology for System Success

Share |


    Technical Training Short On Site Course Quote This three day course provides a systemic overview of how to use Systems Engineering to plan, manage, and execute projects that have significant Commercial-off-the-Shelf (COTS) content. Modern development programs are increasingly characterized by COTS solutions (both hardware and software) in both the military and commercial domains.

    This course focuses on the fundamentals of planning, execution, and follow-through that allow for the delivery of excellent and effective COTS-based systems to ensure the needs of all external and internal stakeholders are met. Participants will learn the necessary adjustments to the fundamental principles of Systems Engineering when dealing with COTS technologies. Numerous examples of COTS systems are presented. Practical information and tools are provided that will help the participants deal with issues that inevitably occur in the real word. Extensive in-class exercises are used to stimulate application of the course material.

    Each student will receive a complete set of lecture notes and an annotated bibliography.



    David D. Walden, ESEP, is an internationally recognized expert in the field of Systems Engineering. He has over 30 years of experience in leadership of systems development as well as in organizational process improvement and quality having worked at McDonnell Douglas and General Dynamics before starting his own consultancy in 2006. He has a BS degree in Electrical Engineering (Valparaiso University) and MS degrees in Electrical Engineering and Computer Science (Washington University in St. Louis) and Management of Technology (University of Minnesota). Mr. Walden is a member of the International Council on Systems Engineering (INCOSE) and is an INCOSE Expert Systems Engineering Professional (ESEP). He is also a Senior Member of the Institute of Electrical and Electronics Engineers (IEEE) and a member of Tau Beta Pi. He is the author or coauthor of over 50 technical reports and professional papers/presentations addressing all aspects of Systems Engineering.
