Then in 1985 I joined the company and set up the SPSS UK office. For 10 years we used SPSS to do our marketing analysis, invoice our customers (Report writer), enter all customer details (DE) and even calculate the annual salary budget. In the end it was replaced by more normal accounting and CRM systems... but for many years it ran the show.
SPSS changed the way the world looked at data analysis. Instead of handing analysis off to statisticians/programmers, it was possible for normal people to solve their problems by themselves.
