Architecture Design Documents (ADD)¶
Version: 1.0.0 | Last Updated: 2025-01-06 | Status: Active
Overview¶
Architecture Design Documents (ADDs) provide detailed technical designs for specific components, features, or systems within MBPanel. Unlike ADRs which capture decisions, ADDs capture comprehensive designs.
What is an ADD?¶
An ADD is a detailed technical specification that includes: - Problem Statement - What problem are we solving? - Requirements - Functional and non-functional requirements - Architecture - Component structure, data flows, interfaces - Implementation Details - Specific implementation approaches - Testing Strategy - How the design will be tested - Migration Strategy - How to transition from current state (if applicable)
ADD Index¶
Active Designs¶
- ADD-001: Multi-Tenant Isolation - Data isolation and tenant separation strategy
- ADD-002: Backup System - Backup scheduling, storage, and restoration architecture
Draft Designs¶
- ADD-003: Billing System - Subscription management and invoicing (DRAFT)

Guidelines¶
When to Write an ADD¶
Create an ADD for: - New major features or subsystems - Significant refactoring of existing systems - Integration with new external services - Complex business logic requiring detailed specification
ADD vs ADR¶
| Aspect | ADR | ADD |
|---|---|---|
| Purpose | Document decisions | Document designs |
| Scope | Single decision | Complete system design |
| Detail | High-level | Detailed specification |
| Lifecycle | Decisions are made | Designs may evolve |
Naming Convention¶
- Format:
000-design-title.md - Use sequential numbers (001, 002, 003...)
- Use kebab-case for titles
- Store in
/docs/architecture/add/
