Ken Hewitt


Ken Hewitt, Manager

More than 40 years of diversified experience and expertise in Information Systems and Information Technology. As a user in the manufacturing industry I applied Information Systems to improve product quality and reliability. As a salesman, I educated customers and prospects in how to make best use of and integrate their computer hardware, software and netware with their business and decision flows. During this time, I was able to learn how successful businesses operated.

Over the last decade, as a litigation consultant, I continue to use my deep industry and Information Technology experience and expertise, and strong statistical/mathematical, and analytical skills to drill down, uncover, and determine what technical and human factors, decisions taken (or not), people, misunderstandings, deviations from good industry systems development life cycles (SDLCs) methodologies, poor project management, bad estimating assumptions, sketchy test regimens and more, are, in fact, the real root causes leading to systems and IT project failure -- and if so, how each party contributed to those failings. I continue to write specific parts of WSRcg’s Expert Reports and Findings when asked.
