Engenharia de Sistemas Introdução à Engenharia de Sistemas e Integração

What is a System? Hall, 1962: A system is a set of objects with relationships between the objects and between their attributes. Kauffman, 1980: A system is a collection of parts which interact with each other to function as a whole. Martin, 1997: A system is a set of integrated end products and their enabling products. Hitchins, 1997: A set of complementary, interacting parts with properties, capabilities and behaviours emerging both from the parts and from their interactions INCOSE, 1998 [International Council on Systems Engineering, non-profit organisation founded in 1990 with over 3500 members in some 35 countries]: Systems Engineering is an interdisciplinary approach and means to enable the realization of successful systems.

What is Systems Engineering? NASA System Engineering Handbook: Systems engineering is "an interdisciplinary approach encompassing the entire technical effort to evolve and verify an integrated and life-cycle balanced set of system people, product, and process solutions that satisfy customer needs.

Objective of Systems Engineering NASA System Engineering Handbook: The objective of systems engineering is to see to it that the system is designed, built, and operated so that it accomplishes its purpose in the most cost-effective way possible, considering performance, cost, schedule, and risk. Cost: The cost of a system is the foregone value of the resources needed to design, build, and operate it. Effectiveness: The effectiveness of a system is a quantitative measure of the degree to which the system's purpose is achieved. Cost-Effectiveness: The cost-effectiveness of a system combines both the cost and the effectiveness of the system in the context of its objectives.

Role of the Systems Engineer

The systems engineer is like the maestro, who knows how the music should sound (the look and function of a design) and has the skills to lead a team in achieving the desired sound (meeting the system requirements). Systems engineers: • Understand the fundamentals of mathematics, physics, and other pertinent sciences, as well as the capabilities of various people and disciplines • Have mastered a technical discipline and learned multiple disciplines • Must understand the end game and overall objectives of the endeavor • Create a vision and approach for attaining the objectives • May be architects or designers • Select and shape the technical issues to be addressed by multidisciplinary teams • Must often interpret and communicate objectives, requirements, system architecture, and design • Are responsible for the design’s technical integrity • Organize and lead multidisciplinary teams • Are responsible for the successful delivery of a complex product or service

Systems Engineer Profile

Technical leadership focuses on a system’s technical design and technical integrity throughout its lifecycle • Systems management focuses on managing the complexity associated with having many technical disciplines, multiple organizations, and hundreds or thousands of people engaged in a highly technical activity
