Describe the development process of Object oriented methods
Object oriented methods have roots which are strongly anchored back in the 60s, functional and structured methods were first to be used. This is not very uncommon, as functional methods are inspired directly by computer architecture (a proven domain, well known to computer scientists).

Later it was felt which hardware should act as servant of the software which is executed on it rather than imposing the architectural constraints on system development process.
