Interactive EasyFlow
Easyflow was one of the first diagramming and flow charting software packages available for personal computers. It was produced by HavenTree Software Limited of Kingston, Ontario Canada. HavenTree's mark on history for its product, which was subsequently renamed Interactive Easyflow, is its notable plain-English license.
History
HavenTree was formed in 1981. Easyflow, a DOS-based software package, was the initial name of the company'sflagship offering, which was non-interactive and introduced in 1983. "EasyFlow-Plus" was announced in 1984. Interactive EasyFlow - so named to distinguish it from the preceding products - was offered from 1985 until the early 1990s, when the company dropped the "Interactive" adjective in favour of simply "HavenTree EasyFlow". It offered the software for sale until it filed for protection under Canada's Bankruptcy and Insolvency Act in April 1996. The assets of the company were purchased by SPSS Inc. in 1998.
