Contents: Section 4 (of Technical Processes)
- Technical Processes and Supporting Activities
- Needs and Requirements
- Summary of Technical Processes
Technical Process and Supporting Activities
- The technical processes are invoked throughout the system life cycle.
- Definition: Define the requirements and produce effective system products and services.
Technical Processes
- Enable Systems Engineers to coordinate interactions between engineering specialists, stakeholders, operators, and other relevant parties.
- Address societal expectations and legislated requirements.
- Drive system solutions with desired capabilities within performance, environment, external interfaces, and design constraints.
Needs and Requirements
- Technical processes begin with developing needs and then requirements.
Needs
- Are things that are wanted or required.
- Often describe lacking capabilities desired by stakeholders.
- Three contexts:
- Projects involving internal customers.
- Development under contracts with external entities.
- Entrepreneurial development anticipating future sales.
Requirements
- Formal structured statements that can be verified and validated.
- May have multiple requirements defined for a single need.
Architecture Definition
- Overview of process
- Elaboration
Description (Architecture Definition)
- System architecture & design activities enable the creation of global solutions based on principles, concepts, and properties.
- Addresses problem/opportunity by defining system requirements.
Description (Architecture Definition) (2)
- Addresses high-level system structure, concepts, properties, and characteristics.
- Focuses on technology, physical, structural, environmental, and operational properties.
Description (Architecture Definition)(3)
- Deals with architecture definition; aggregates and insights from requirements; and consideration of suitability, viability, and affordability.
- Uses architectural descriptions, feasibility analysis, balance trades, and vetted requirements.
Description (Architecture Definition) (4)
- Architecture definition is a process creating views and models to assess alternative architectures.
- This process optimizes for balance and appropriate risk level.
Description (Architecture Definition) (5)
- Architecture definition is iterative, requiring participation of systems engineers and specialists with system domain knowledge. Process continues and is recursively applied.

- Experts perform models, simulations, and analysis.
Design Definition
- Overview, elaboration, related content.
Design Definition -- Purpose, Description, Inputs/Outputs, and Process Activities
