Once upon a time, I started a consulting business providing services to implement large accounting, HR and manufacturing systems, later called ERP. We started the business focussing on Oracle Applications, and then, when PeopleSoft came to Australia we signed up as their first implementation partner here. PeopleSoft was started by Dave Duffield, and moved from an upstart challenger to Oracle and SAP by entering the HR & Payroll market first (now called HCM for Human Capital Management) and then expanding into accounting and other applications. The company was very successful and after a long battle were eventually swallowed by Oracle.
Now Mr. Duffield is back, doing it again with Workday, an ERP application delivered using a SaaS or on-demand model. The company has raised several substantial rounds of capital and already has started accumulating an impressive customer list include some Fortune 500 companies. Interesting, they list on their customer list some of the major SaaS players such as salesforce.com, Xactly and Astadia, who are using Workday for their back office functions.
I am watching with great interest.
