Three Advantages of Documenting Architecture

(1) Stakeholder communication - the architecture provides a high-level presentation for discussion

(2) System analysis - early architectural design requires analysis and reveals whether requirements can be met

(3) Large-scale reuse - the architecture can be reused across systems with similar requirements

Explanation

The three recognized advantages are: (1) Stakeholder communication - the architecture is a high-level presentation usable by different stakeholders; (2) System analysis - making the architecture explicit requires analysis and shows whether critical requirements like performance and reliability can be met; (3) Large-scale reuse - similar systems often share the same architecture, enabling product-line architectures.
