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).


Functional requirements are organized hierarchically, with core requirements, broken down into sub- and sub-sub-requirements. around the core functions of repositories holding archival material. ICA-AtoM currently focuses on two functions, breaking these down into sub- and sub-sub-requirements:

  1. Establish intellectual and administrative control over archival materials
  2. Provide an interface that supports user interaction with the system (create, read, update, delete, search


Each functional requirement includes the following information:

Requirement number FR-x.x.x (unique tracking number assigned to requirement)
Requirement name Descriptive name assigned to requirement.
Requirement specification Brief description of requirement: system must do X.
Sub-requirements If the requirement is broken down into sub-requirements, provides links to these.
Requirement quotation Links to standards or other documents: why must the system be able to do X?
Associated metadata requirements Links to functional requirements: what data must the system capture in order to be able to do X?
Associated quality requirements Links to quality requirements: what design and interface features must the system have to do X well?
Associated technical requirements Links to technical requirements: what system architecture, hardware / software configurations, and programming rules must the system 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.
User Manual sections Links to the User manual sections that provide step-by-step instructions for doing X.
