    Study Notes

    Systems Engineering (SE) Overview

    • SE is an integrated approach to managing complex systems.
    • It focuses on ensuring system components work together to achieve overall goals.
    • SE practitioners use a holistic life cycle approach for successful system projects.
    • SE aims for systems that effectively fulfill their purpose and are resilient to operational issues.

    Definition of Systems Engineering

    • SE is a transdisciplinary, integrative approach for realizing, using, and retiring systems.
    • It leverages systems principles, concepts, and scientific/technological/management methods.
    • Key SE focuses include stakeholder goals, life cycle models, alternative solutions, and verification/validation.
    • SE facilitates integration of different disciplines for successful system development.

    Definition of a System

    • A system is comprised of interacting parts, exhibiting behavior distinct from individual parts.
    • Systems can be physical, conceptual, or a combination of both.
    • Physical systems involve matter, energy, and information.
    • Conceptual systems are abstract, with meaning arising from constituent parts and their interactions.
    • Complete systems include all necessary equipment, documentation, and personnel.

    Engineered Systems

    • Engineered systems are designed to interact with an anticipated environment to achieve specific goals.
    • They can comprise people, products, services, information, processes, and/or natural elements.

    Origins and Evolution of SE

    • SE aspects have existed throughout history but formally emerged in the mid-20th century.
    • Key milestones include Bell Telephone Laboratories' early applications in the 1940s.
    • The need for multidisciplinary teams in analyzing air defense systems (1930s) is an earlier example.
    • The RAND Corporation played a role in developing systems analysis.
    • Formal SE education, including courses at MIT, contributed to its growth.
    • The creation of the professional society, INCOSE, furthered adoption of SE.
    • Incorporation of the international standard, ISO/IEC 15288, established its recognition.

    Importance of Systems Engineering

    • SE aims to deliver the right product/service within budget and time constraints.
    • Effective SE relies on common system understanding/vision among stakeholders.
    • SE use of proven, standard methods ensures continuous, life-cycle approach.
    • Importance of SE is particularly apparent in highly complex systems, like those using commercially available products or system of systems.

    SE in Modern Systems

    • Modern systems typically rely on integrating multiple, independently managed parts/systems, thus increasing complexity.
    • Agile methods and modeling languages like SysML have enabled effective complexity management in SE.
    • Model Based Systems Engineering (MBSE) is becoming increasingly common, particularly in initial design and requirement phases.
    • This adoption of digital engineering (DE) trends is expected by standards organizations.

    SE Value Quantification

    • Studies like Honour (2013) demonstrably show a positive correlation between SE effort and project cost/schedule compliance.
    • A study showed positive ROI for SE, with higher ROI associated with less established use of SE processes.
    • Data shows that optimal SE efforts, as a fraction of total project cost, yield better success.
    • Studies by NDIA, IEEE, and SEI further reinforce the importance of SE for project success.
