Enterprise and System Architecture Workflows

This document outlines the enterprise and system architecture workflows for SaaS products generated by the ConnectSoft AI Software Factory. These workflows transform product visions, requirements, and designs into formal, scalable, secure system blueprints through enterprise architecture, solution architecture, event-driven architecture, API design, and technical leadership.

Enterprise and system architecture workflows are orchestrated by the Enterprise Architect Agent, Solution Architect Agent, Event-Driven Architect Agent, API Designer Agent, and Tech Lead Agent, working collaboratively to ensure systems are modular, scalable, event-driven, secure, and aligned with Clean Architecture and Domain-Driven Design principles.

Overview

Enterprise and system architecture workflows cover the technical design lifecycle:

1. Enterprise Architecture - Define system-wide architecture principles and domain boundaries
2. Solution Architecture - Design concrete system components and service decompositions
3. Event-Driven Architecture - Design domain events, event flows, and asynchronous communication
4. API Design - Define API interfaces, contracts, and versioning strategies
5. Technical Leadership - Oversee technical translation and ensure feasibility
