Study Notes

Needs are capabilities or desires for a system, arising in various contexts of SE, including internal projects, external agreements, and entrepreneurship.
Requirements are formal statements that can be verified and validated, derived from needs.
Business or mission analysis process:
- Begins with enterprise business vision, strategies, and goals.
- Transforms needs into business requirements, captured in a Business Requirements Specification (BRS).
Stakeholder needs and requirements definition process:
- Guided by enterprise ConOps and system preliminary OpsCon.
- Elicits stakeholder needs and transforms them into formal stakeholder requirements, captured in a Stakeholder Requirements Specification (StRS).
System requirements definition process:
- Transforms stakeholder requirements into system requirements, captured in a System Requirements Specification (SyRS).
Architecture definition process:
- Establishes alternative system architectures and selects one.
Business or mission analysis process overview:
- Defines the business or mission problem or opportunity.
- Characterizes solution space and identifies potential solution classes.
- ISO/IEC/IEEE 15288 process per ISO/IEC/IEEE 6.4.1.1.
The Stakeholder Needs and Requirements Definition process aims to define stakeholder requirements for a system that caters to the needs of users and other stakeholders in a defined environment.
Successful projects rely on meeting the requirements of all stakeholders throughout the system's lifecycle.
Stakeholders include users, operators, decision-makers, regulatory bodies, and society at large, among others.
Inputs and outputs for the process are listed in Figure 4.4 and include stakeholder needs, operational concept, validation criteria, and stakeholder requirements, among others.
Preparing for the stakeholder needs and requirements definition includes determining stakeholders, eliciting stakeholder needs, and defining the operational concept.
The stakeholder needs are defined through the elicitation process from identified stakeholders, and the operational concept is developed, which includes identifying operational scenarios, system interactions, and constraints.
The stakeholder requirements are transformed from needs by considering scenarios, interactions, constraints, and critical qualities.
Validation criteria for stakeholder requirements, such as measures of effectiveness (MOEs) and measures of suitability (MOSs), are defined to determine the operational success of the solution.
Analyzing stakeholder requirements helps to identify potential issues, and stakeholder requirements are managed throughout the process.
