Study Notes

Systems Engineering (SE) Overview

SE is a multidisciplinary field focused on creating, using, and retiring engineered systems.
It aims for efficient and effective system performance, integrating all components' actions.
SE uses "systems thinking" to understand how system parts interact.
Key SE activities include defining stakeholder needs, creating life-cycle models, assessing solutions, designing, verifying, and validating systems.
SE practitioners are facilitators, integrating technical and management expertise.
A major focus is risk management, like schedule delays or budget overruns.
A system is a collection of interacting parts that display behaviors not found in individual parts. Systems can be physical, conceptual, or both.
Engineered systems are designed to interact with their environment to fulfill intended purposes.

Importance of Systems Engineering

SE ensures successful delivery of products and services, especially in complex projects.
It aligns stakeholder needs with technical solutions, aiming for on-time, within-budget, and high-performance projects.
Key reasons for SE value include managing complexity of integrated systems.
SE also reduces risk and improves efficiency/timelines with approaches like Model-Based Systems Engineering (MBSE).
Early risk management in SE reduces lifecycle costs, managing over 80% during early design phases.
Critical in complex industries like aerospace, defense, and infrastructure. Enhances reliability and adaptability.

Systems Concepts

System of Interest (SoI): The primary focus of SE efforts, surrounded by the system environment (users, external systems, enabling systems).
System Boundary: Defines what belongs to the system vs. its environment. Crucial for understanding interactions.
Emergence: New properties or behaviors arising from interactions between system components, not present in individual parts (e.g., system safety, resilience).
System States and Modes: Variations in system operation influencing functionality and performance.
Interfacing and Enabling Systems: Interfacing systems directly interact with the SoI; enabling systems support the SoI operation. SE manages these crucial interactions.

Systems Engineering Foundations

Uncertainty Management: Two types of uncertainty:
- Epistemic: Knowledge gaps/incomplete information (can be reduced).
- Aleatory: Inherent randomness/variability (managed, not eliminated).
Cognitive Bias: SE emphasizes objective evaluation processes to mitigate biases like confirmation bias and anchoring.
Principles and Heuristics: Sound SE practices like balancing technical/business goals, integrating stakeholder inputs, using iterative development cycles.
