When I was in South Africa last fall, a systems engineer told me about an organization called INCOSE. I was not familiar with it but he told me that they had many of the same goals as the IIBA so I decided to take a look.
Some information from their website:
The International Council on Systems Engineering (INCOSE) is a not-for-profit membership organization founded to develop and disseminate the interdisciplinary principles and practices that enable the realization of successful systems.
Advance the state of the art and practice of systems engineering in industry, academia, and government by promoting interdisciplinary, scalable approaches to produce technologically appropriate solutions that meet societal needs.
What is Systems Engineering?
Systems Engineering is an interdisciplinary approach and means to enable the realization of successful systems. It focuses on defining customer needs and required functionality early in the development cycle, documenting requirements, then proceeding with design synthesis and system validation while considering the complete problem . . .
This organization was founded in 1990 and has over 5000 members worldwide. They have numerous chapters, a body of knowledge and a certification program. I reviewed the body of knowledge (G2SEbok) and it contains many of the same topics as the BABOK.
So the question is “What is the difference between a BA and a Systems Engineer?”
