Study Notes

What is a System?

A system is a combination of resources—human, material, equipment, software, etc.—integrated to meet specific operational requirements.
Systems are formed by interdependent elements that function collectively as a unified whole.
They consist of equipment, skills, and techniques that support operational roles.
A system's main purpose is to satisfy a stated need or objective through interrelated components.

General Characteristics of Systems

Systems combine various resources effectively to achieve objectives.
They operate within a hierarchical structure, influenced by higher-level systems.
Systems can be broken down into subsystems and components, which must be understood for design.
Every system must have a purpose, termed as its "mission," to provide solutions to business problems.

Classifications of Systems

Natural vs. Human-made Systems:
- Natural systems occur through natural processes.
- Human-made systems involve human intervention and may include modifications to natural systems.
Physical vs. Conceptual Systems:
- Physical systems have real components.
- Conceptual systems are represented by symbols and abstract models.
Static vs. Dynamic Systems:
- Static systems have structure without activity, such as a bridge.
- Dynamic systems have both structure and interaction, like a school system.
Open vs. Closed Systems:
- Closed systems do not significantly interact with their environment.
- Open systems exchange information and materials with their environment, critical for globalization and collaboration.

Trends Impacting Systems

Increased international competition driven by better communication and transportation.
Greater reliance on outsourcing and procurement of commercial off-the-shelf (COTS) items.
A declining number of manufacturers, leading to the need for reliable component sources.
Rising life cycle costs of systems, emphasizing the operational and support costs alongside acquisition costs.

What is Systems Engineering?

An interdisciplinary approach aimed at successful system realization by addressing customer needs and functionality early in the development cycle.
It involves a top-down, iterative process, including requirements analysis, functional analysis, design synthesis, and validation.
Ensures integration of all aspects of a project or system for optimal functionality over its life cycle.

Systems Engineering Processes

Encompasses various stages: conceptual design, preliminary design, detailed design and testing, production, utilization, and eventual retirement of systems.

Systems Engineering Management

Involves oversight of systems engineering processes, including monitoring, directing, and reporting.
Key functions include technical reviews, risk management, configuration management, and integration management.

Systems Engineering Tools

Tools range from techniques and processes to information systems and standards, including requirements management and analytical tools.

Systems engineering interacts with diverse fields such as project management, quality assurance, hardware and software engineering, and human factors engineering.

Traits & Attributes of a Successful Systems Engineer

Effective problem solver with a willingness to face challenges.
Well-rounded technical knowledge with broad interests.
Analytical and creative thinker with strong communication and leadership skills.
