System Development Phases

• System Design: analyzes and interprets the business of the proposed system by studying the user requirements document.
• Module Design: divides the system into manageable components, also known as Low-Level Design.
• System Testing: evaluates the system to ensure it meets its requirements and performs as expected.

System Engineering

• Systems Engineering: an interdisciplinary field that focuses on complex system design, integration, and management.
• It considers a system's needs, functionalities, performance, risks, and stakeholders, as well as its technical and non-technical components.

System Characteristics

• Robustness: the capacity to operate in the face of internal or external factors.
• Durability: the amount of time a system may run its specified program, usually quantified as service life.
• Flexibility/Adaptability: the system's capacity to adjust to new roles or responsibilities or to operate at a different degree of efficiency.
• Maintainability: the act of keeping the system running, including the amount of time and money needed, likelihood of failure, and quantity of spare parts needed.

Requirements Analysis

• Requirements Allocation: determines the needs for various system components, including subsystems, interfaces, and components, based on their roles, capabilities, and limitations.
• Analyzing Requirements: examines the collected requirements to ensure they are complete, consistent, and feasible.
• Documenting Requirements: creates a comprehensive and unambiguous requirements specification document that serves as a basis for system design and development.

System Modeling and Design

• System Modeling: creates a simplified representation of a system to understand its behavior and performance.
• Architecture Design: includes the list of modules, a synopsis of each module's operation, interface map, dependencies, database tables, architectural diagrams, and technological details.

Testing and Validation

• Unit Testing: develops plans during the module design phase to eliminate bugs in code or unit level.
• Validation: uses a dynamic analysis approach, and code execution is used for testing to ensure the software satisfies the client's needs and expectations.

Systems Classification

• Dynamic Systems: capable of action or change.
• Simple Systems: consist of a few parts and a direct structure, fully knowable and predictable.
• Natural Systems: biological classification based upon morphological and anatomical relationships and affinities.
