Stephen J. Mellor (born 1952) is a British computer scientist, developer of the Shlaer–Mellor method and Executable UML, and signatory to the Agile Manifesto.


Mellor received a BA in computer science from the University of Essex in 1974, and started working at CERN in Geneva, Switzerland as a programmer in BCPL. In 1977 he became software engineer at the Lawrence Berkeley Laboratory, and in 1982 consultant at Yourdon, Inc..[1]

At Yourdon in cooperation with Paul Ward they developed the Ward–Mellor method, and published the book-series Structured Development for Real Time Systems in 1985. Together with Sally Shlaer he founded Project Technology in 1985. That company was acquired by Mentor Graphics in 2004.[1] Mellor stayed as chief scientist of the Embedded Systems Division at Mentor Graphics for another two years, and is self-employed since 2006.

Since 1998 Mellor has contributed to the Object Management Group, chairing the consortium that added executable actions to the UML, and the specification of model-driven architecture (MDA). He is also chairing the advisory board of the IEEE Software magazine.[2] Since 2013, Mellor has served as CTO for the Industrial Internet Consortium.[3]
