Purpose
Functional requirements state what the system must be able to do. The requirements provide:
- Parameters for designing the system.
- Criteria for testing the system (used in initial release and future iterations and upgrades).
- Planning guidelines for developing the system (improve existing or add new functionality).
- Documentation for standards compliance (link requirements to relevant international or national descriptive standards)
- A framework for structuring user-end documentation (step-by-step procedures for how to do things in the system).
Organization
Functional requirements are organized hierarchically, with high-level requirements broken down into sub- and sub-sub-requirements. To facilitate cross-references and links, each requirement has been assigned an alpha-numeric code: the alpha prefix designates the type of requirement (FR = functional requirement), the number establishes its position in the hierarchy. Six main functional requirements have been identified:
- FR-1 Implement a system of control
- FR-2 Add / edit content
- FR-3 Translate content
- FR-4 Access content
- FR-5 Import / export content
- FR-6 Administer the system
Information
Each functional requirement includes some or all of the following information:
- Requirement number (FR-x.x.x, unique tracking number assigned to requirement).
- Requirement name: descriptive name assigned to requirement.
- Specification: brief description of requirement; users of the application must be able to do X, the system must be able to do X.
- Source quotations: links to standards or other documents: why must the applicable be able to do X?
- Associated metadata requirements: what data must the application capture in order to be able to do X?
- Associated quality requirements: what design and interface features must the application have to do X well?
- Associated technical requirements: what system architecture, hardware / software configurations, and programming rules must the application implement to do X?
- ICA-AtoM implementation: brief description of how ICA-AtoM implements X.
- Known issues: brief indication of known problems or limitations in the current version of ICA-AtoM that should be addressed in future releases.
- Use cases: links to descriptions of user-end scenarios relating to the requirement and how they are handled in ICA-AtoM.
- User Manual sections: links to the User manual sections that provide step-by-step instructions for doing X.
Note that most of this detail will only be found at the lower-level requirements. Higher-level requirements will typically only include the requirement name, number, specification, and source quotation, with links to the lower-level sub-requirements.
