SOUP / external service

SOUP (software of unknown provenance) or an external service: a third-party component the system incorporates or depends on. The analysis states what the system requires of it (function, performance, availability and data protection) and the agreement that binds it, which for PHI is a business associate agreement. Each one is recorded as SOUP or as an external-system interface, with the reason.

Requirement

A statement of what the system must do, or the constraint it must respect, in the target state. It is written with one "shall", one subject (the system or a role) and one behavior, and carries an id, a type, a level, an owner role, a scope, a rationale, a source, a verification method with acceptance criteria, a priority, a phase and a lifecycle status.

Requirement attribute

A named field every requirement carries: id, title, statement, type, level, owner, scope, rationale, source, priority, phase, status, verification, validation, risk, medical flags, trace, and change history and baseline. Together the attributes are the requirement ontology of the Analysis Document Standard.

Requirement type

The kind of a requirement. One of: business, stakeholder, functional, quality, service-level, security, regulatory, constraint, architecture, interface, data, operation or risk-control.

Requirement level

Where a requirement sits in the decomposition. One of: business, stakeholder, system or software.

Owner role (requirement owner)

The requirement owner is a role taken from the role register, never a person. Every requirement has an owner role, such as the business owner, the PHI owner or the platform owner. A person's name appears only in the role register, as the current holder of the role.
