Architecture Requirements Specification

Purpose

The Architecture Requirements Specification provides a set of quantitative statements that outline what an implementation project must do in order to comply with the architecture. An Architecture Requirements Specification will typically form a major component of an implementation contract or contract for more detailed Architecture Definition.
As mentioned above, the Architecture Requirements Specification is a companion to the Architecture Definition Document, with a complementary objective:

• The Architecture Definition Document provides a qualitative view of the solution and aims to communicate the intent of the architect
• The Architecture Requirements Specification provides a quantitative view of the solution, stating measurable criteria that must be met during the implementation of the architecture

Content

Typical contents of an Architecture Requirements Specification are:

• Success measures
• Architecture requirements
• Business service contracts
• Application service contracts
• Implementation guidelines
• Implementation specifications
• Implementation standards
• Interoperability requirements
• IT Service Management requirements
• Constraints
• Assumptions
