This Systems Engineering book is mostly concerned with the systems architecture, the development, and the management of the people involved; the system engineering practitioners who work on their own, and those who work in groups to design the systems applicable to users, in multi-national corporations, academia, and government departments. Based on the contents, training courses can be prepared to suit the candidates, mainly workshops concerned with human-computer interactions, and systems development. In systems engineering, the major theme is the responsibility to the system user, and the company; to help with their problems and requirements in designing and developing a system. The book covers systems engineering, and emergent technologies as a service given to all types of businesses, in most environments and as a tool at work.
