Master of Science System Engineering and Management (2023), Lecturer, and Teaching Assistant – Massachusetts Institute of Technology (MIT)            


Rob led setting the John Deere Enterprise Systems Engineering strategic direction, developing, and sustaining Systems Engineering methods and tools to ensure rigor in the application and providing advanced expertise in leading Systems Engineering subject matter expert practitioners.  His responsibility also includes managing academic relationships and programs with the Massachusetts Institute of Technology (MIT) and California Technical Institute (Caltech) and maintaining a relationship with INCOSE, the International Council on Systems Engineering, to keep up to date on Systems Engineering developments and provide input to guide the System Engineering initiative though out John Deere.     


Rob Day has over 38 years of experience managing resources to exceed high-performing organizations' goals in System Engineering, System Architecture, System Analysis, Product Design, Six Sigma & Design for Six Sigma, Quality Management, Operations Management, and Project Management. Since joining John Deere in 1998, Rob has held increasingly responsible leadership positions in System Engineering, Product Design, Quality Engineering, Six Sigma services, and Test Engineering at the John Deere Harvester Works, JD Seeding, and in both Corporate and Advanced Technology Divisional organizations. Rob’s global experience includes an assignment as a Quality & Test engineer at the John Deere operations in Zweibrücken, Germany. Rob’s experiences include Global Systems Engineering Manager, Seeding and Tillage, and Manager of Enterprise Six Sigma, Metrology, and Dimensional Management. During this time, Rob has transitioned the enterprise through the design, development, and early execution of new strategies in the above areas and critical innovation projects.


Rob has been an ASQ member since 2002, ASQ CSSBB - 2003 to Current, and a John Deere Ag Division Certified Master Black Belt. There is an evolving capability at Deere in Systems Engineering to improve how we deliver new products and services to the market at an exceptional quality level.  The company has a large body of trained Systems Engineers, pockets of Systems Engineering excellence, and robust EPDP.  However, the Enterprise has much variability on how Systems Engineering is used and integrated into our core processes.  Rob’s Enterprise Systems Engineering lead position was established in 2015 for these reasons.


Before joining John Deere, Rob worked at Hamilton Sundstrand (Formerly Sundstrand Aerospace), a UTC division in Rockford, Illinois, for 12 years, where he held both Design, Test, Systems Engineering and Leadership positions.


He holds a degree in Manufacturing Engineering from Bradley University in Peoria, Illinois, and Graduate Degrees and Certificates from Caltech and MIT in Systems Engineering & Management.


Rob is also an adjunct instructor in the Caltech/John Deere System Engineering Program, jointly developed to connect the academic with the practical application of System Engineering principles.  He holds this as an honor and is humbled by the opportunity to instruct with Caltech.  He also is a teaching assistant, guest lecturer, and adjunct professor in the MITsdm program.  Rob has coached/mentored system development projects for Deere & Company, Chevron, Shell, and numerous others large fortune 500 firms.


Rob holds numerous patents, published papers at MIT, and in July 2019, presented in conjunction with PTC at the INCOSE IS2019.  In 2023 he contributed significantly to the field of system engineering and management with his MIT Thesis on Operational Analysis and Mission Engineering: A strategy and framework to analyze any industrial ecosystem.
