3SL (Structured Software Systems Limited) was founded in the United Kingdom in 1987 to develop CASE tools. Its founders were all engineers with a Systems Engineering background in the UK naval defence industry.
In 1989, 3SL signed an exclusive distributorship with Yourdon Inc. to allow Yourdon to sell 3SL tools on UNIX platforms branded with the Yourdon name.
This agreement amicably ended in 1992 when 3SL commenced sales and marketing in its own name.
Initially the company marketed Cradle as a CASE tool. Subsequently, however, the product has been expanded to provide a fully integrated Systems Engineering Toolset which supports all engineering disciplines.
The company now has two offices in the United Kingdom in Henley-On-Thames (Oxfordshire) and Barrow-In-Furness (Cumbria).
Cradle is a British product developed and supported in the United Kingdom
We have an ever expanding network of distributors throughout Europe and across the World.
Current UK customers include GEC, GPT, British Aerospace, CAA, British Steel, Royal Ordnance, Defence Research Agency, Scomagg, Siemens, Vickers.
