Study Notes
Requirements Discovery and Understanding
- Interactions with stakeholders help identify system requirements and reveal domain requirements.
- Documentation reviews also assist in uncovering relevant requirements.
Requirements Classification and Organization
- Unstructured requirements are grouped into coherent clusters for easier analysis.
- Organized requirements facilitate clearer understanding and communication among stakeholders.
Requirements Prioritization and Negotiation
- Conflicting requirements from multiple stakeholders must be negotiated and prioritized.
- Stakeholder meetings often required to reach agreements on compromise requirements.
Viewpoints in Requirements Gathering
- A viewpoint collects and organizes requirements from stakeholders with common interests.
- Each viewpoint contributes unique system requirements from various stakeholder perspectives.
Iterative Requirements Elicitation Process
- The process of requirements elicitation involves continual feedback between discovery, analysis, and documentation.
- Understanding of requirements improves with each iteration until a final requirements document is produced.
Ethnographic Analysis in Requirements Gathering
- Ethnography aids in understanding existing systems but may not foster innovation.
- Innovations from ethnographic studies are less applicable for broader organizational or domain requirements.
Stories and Scenarios
- Real-life examples, such as stories and scenarios, help capture system requirements effectively.
- These narratives facilitate discussions and make abstract requirements more relatable for stakeholders.
Example: Uploading Photos to KidsTakePics
- Users upload photos saved on tablets or laptops after logging in, selecting project names, and inputting keywords.
- The system generates notifications for moderators when new content is uploaded and informs users of the upload status.
Graphical Notations and Specifications
- Graphical models, like UML use case and sequence diagrams, define functional system requirements.
- Mathematical specifications can clarify requirements but may be inaccessible to customers.
System Requirements versus User Requirements
- System requirements detail how software engineers will implement user requirements, serving as a blueprint for design.
- While primarily focusing on external behaviors, some design insights may be necessary for complex systems.
Structured Language and Requirements Specification
- Structured language notations help impose uniformity and reduce ambiguity in requirements.
- Templates and structured forms guide the creation and management of system requirements.
Key Elements in Functional Requirements Specification
- Specifications should clearly describe functions, inputs, outputs, and their respective origins and destinations.
- A well-defined structured format for functional requirements improves clarity and understanding among all stakeholders.
