Rise to Success

Duffield began his career at IBM as a marketing representative and systems engineer. In 1968, he left IBM to found Information Associates, which developed software for university exam scheduling. Later, he founded Integral Systems, a human resources management systems vendor. In 1979, Duffield started Business Software Corporation, providing real-time human resources and payroll applications. However, his most significant achievements came with PeopleSoft, founded in 1987, which became the world's second-largest application software company before being acquired by Oracle in 2005. In 2005, Duffield co-founded Workday, Inc., which provides cloud-based human capital management and financial management software.

His ability to identify market needs and deliver innovative software solutions has been pivotal to his success. PeopleSoft's client-server HRMS application suite was a groundbreaking innovation.
