Study Notes
Requirements Labeling Methods
- Hierarchical numbering is a simple and compact method, but numeric labels don't provide information about the intent of a requirement.
- Cons of hierarchical numbering: labels can grow to many digits, and word processors don't generate persistent labels.
- Mitigation: number major sections hierarchically and identify individual functional requirements with a short text code followed by a sequence number (e.g., Section 3.5 Editor Functions has ED-1, ED-2… etc.).
Hierarchical Textual Tags
- Tags are structured, meaningful, and unaffected by adding, deleting, or moving other requirements (e.g., Print.ConfirmCopies).
User Interfaces and the SRS
- Incorporating user interface designs in the SRS has both benefits (makes requirements tangible) and drawbacks (can make the SRS large and scare people).
- Don't expect developers to derive underlying functionality and data relationships from screen shots.
SRS Readability Tips
- Use an appropriate template to organize information.
- Label and style sections, subsections, and individual requirements consistently.
- Use visual emphasis (bold, underline, italics, color, and fonts) consistently.
- Create a table of contents to help readers find information.
- Number all figures and tables, give them captions, and refer to them by number.
Requirements Labeling Methods – Sequence Number
- Pros: easy to retain a unique identifier, doesn't imply any order.
- Cons: doesn't provide logical or hierarchical grouping of related requirements.
Requirements Specification
- The result of requirements development is a documented agreement among stakeholders about the product to be built.
- The vision & scope document contains business requirements, and user requirements can be captured in the form of use cases.
- Functional and nonfunctional requirements are often stored in a software requirements specification (SRS).
SRS
- The SRS states the functions, characteristics, and constraints of a software system.
- It should describe the system's behaviors under various conditions and desired system qualities.
- It is the basis for project planning, design, and coding, as well as system testing and user documentation.
SRS Audience
- A single requirements deliverable cannot meet the needs of all audiences.
- Different models are created to cater to different audiences (e.g., business objectives, high-level big picture, user's perspective, or detailed requirements).
Labeling Requirements
- Every requirement needs a unique and persistent identifier.
- This helps refer to specific requirements in change requests, modification history, or requirements traceability matrix.
