2 Engenharia de Sistemas
Introdução à Engenharia de Sistemas e Integração

3 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.


5 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.

6 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.

8 Role of the Systems Engineer

9 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


11 Systems Engineer Profile

12 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
