Systems Engineering : The Art of Simplifying the Complexity

Systems Engineering (SE) 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, and
then proceeding with design synthesis and system validation
while considering the complete problem: operations, cost and
schedule, performance, training and support, test, manufacturing,
and disposal.

SE considers both the business and the technical needs of all
customers with the goal of providing a quality product that meets
the user needs.
