FEA: Feature Specification

Document Type

Code: FEA
Name: Feature Specification
Domain: Product & Service

Abstract

This specification defines the Feature Specification document type within the BSpec 1.0 Universal Business Specification Standard. It establishes normative requirements, structured templates, and implementation guidance for organizations documenting feature specification within the product-service domain. This specification enables systematic, machine-readable documentation that supports strategic planning, operational execution, and organizational alignment.

Purpose and Scope

The Feature Specification defines detailed functional requirements for individual product features, bridging high-level product requirements with technical implementation. It ensures features deliver clear user value while meeting quality and performance standards.

Insufficient edge case consideration: Missing error scenarios and boundary conditions
Poor cross-team communication: Misaligned expectations between teams

Success Patterns

User-centered design: Validate design with real users before implementation
Incremental delivery: Break features into smaller, valuable increments
Cross-functional collaboration: Include design, engineering, and product in specification
Comprehensive testing: Test early and often throughout development
