Generated Narrative: CodeSystem requirement-category

This case-sensitive code system http://hl7.org/fhir/requirement-category defines the following codes in a Is-A hierarchy:

LvlCodeDisplayDefinition
1behavioral Categories related to how the system behaves
2\u00a0\u00a0business BusinessRequirements relating to the business operations of the entities responsible for a system
2\u00a0\u00a0functional FunctionalRequirements related to what the system does (inputs turned into outputs)
3\u00a0\u00a0\u00a0\u00a0exchange ExchangeRequirements relating to when, how, or what data is exchanged with other systems
3\u00a0\u00a0\u00a0\u00a0processing ProcessingRequirements related to how data must be analyzed, transformed, considered, or otherwise used within a system
3\u00a0\u00a0\u00a0\u00a0storage StorageRequirements related to if or how data is persisted in a system
2\u00a0\u00a0non-functional Non-functionalRequirements related to how the system accomplishes functional requirements
3\u00a0\u00a0\u00a0\u00a0availability AvailabilityRequirements related to how and when a system needs to be reachable and useable
3\u00a0\u00a0\u00a0\u00a0ui User InterfaceRequirements related to how information is collected from and exposed to humans (or animals)
4\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0ui-accessibility UI AccessibilityRequirements around user interface that ensure a satisfactory experience for users from different backgrounds or with varying physical, cognitive, and/or sensory abilities
4\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0ui-consistency UI ConsistencyRequirements around ensuring that different implementations have sufficiently aligned appearance and mechanisms of interaction
4\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0ui-usability UI UsabilityRequirements related to the intuitiveness, simplicity, and ease-of-use of a user-interface
3\u00a0\u00a0\u00a0\u00a0security Security/PrivacyRequirements that ensure that data is appropriately protected from threats and respects rules around what parties are permitted to access or manipulate
3\u00a0\u00a0\u00a0\u00a0safety SafetyRequirements that ensure that system operation does not negatively impact the wellbeing of people or assets
3\u00a0\u00a0\u00a0\u00a0performance Performance/ScalabilityRequirements that deal with timeliness of processing and/or responsiveness under differing levels of load/volume
1source Categories related to where the requirement came from
