- Context Mapping: Life Expectancy - I was at a client recently, a large insurance and banking company. The organization is over 200 years old. Some of the software is only slightly younger: they first started automating some 40 years ago. Some of the people I spoke with, have been around almost as long. They have, depending on who you’re asking, 600 applications in production. The majority is written in Java and COBOL. [Mathias Verraes]
