# Specification Quality Checklist: Portfolio Performance Views

**Purpose**: Validate specification completeness and quality before proceeding to planning
**Created**: 2026-03-16
**Feature**: [spec.md](../spec.md)

## Content Quality

- [x] No implementation details (languages, frameworks, APIs)
- [x] Focused on user value and business needs
- [x] Written for non-technical stakeholders
- [x] All mandatory sections completed

## Requirement Completeness

- [x] No [NEEDS CLARIFICATION] markers remain
- [x] Requirements are testable and unambiguous
- [x] Success criteria are measurable
- [x] Success criteria are technology-agnostic (no implementation details)
- [x] All acceptance scenarios are defined
- [x] Edge cases are identified
- [x] Scope is clearly bounded
- [x] Dependencies and assumptions identified

## Feature Readiness

- [x] All functional requirements have clear acceptance criteria
- [x] User scenarios cover primary flows
- [x] Feature meets measurable outcomes defined in Success Criteria
- [x] No implementation details leak into specification

## Notes

- All items pass validation. The spec references existing data model entity names (Entity, Partnership, etc.) for clarity but does not prescribe implementation approach.
- The "Computed Metrics" section documents calculation formulas at a business-logic level without specifying technology.
- The Assumptions section documents reasonable defaults for ambiguous areas (asset class mapping, valuation year default, GL reference handling, enum mapping for missing asset classes).
