Developer Rule (Most Important)

Only 4 core engines should exist in the entire platform:

1. Foundation Engine (Set 1)


2. SOP & Workflow Engine (Set 2)


3. Document Engine (Set 6)


4. Billing Engine (Set 16)



All other sets must reuse these engines instead of creating duplicate workflow, document, access, API, or billing logic. This aligns with the architecture discussions and implementation plan.


Based on the implementation plan and your earlier requirement that Phase 1 should focus on login, blogs, document vault, task management, and a foundation that later modules build upon, I would define Phase 1 like this for the development team:

ERA Platform – Phase 1 (MVP Foundation)

Objective

Build the core platform infrastructure that every future module (RERA, Loan, Accounting, Marketplace, etc.) will reuse.

Considering the entire ERA platform you've planned (16 sets, ~90–100 modules, multiple user roles, workflows, billing, RERA, loans, accounting, valuation, marketplace, etc.), Phase 1 is relatively small in feature count but very significant in architecture.
Phase 1 Foundation, Authentication, RBAC, Organization, Blog, Document Vault, Task Management, Dashboard, Notifications, Core APIs 20–25%
Phase 2 Workflow Engine, SOP, Chat, Professional Platform, RERA Core 20–25%
Phase 3 Projects, Accounting, GST, Loan, Document Automation 20–25%
Phase 4 Property Marketplace, Valuation, Design, Growth, Monetization 20–25%
Phase 5 AI, Analytics, Public APIs, Performance, Advanced Integrations 10–15%
