Feature Branch: 001-1-target-sectors Created: 2025-10-04 Status: Draft Input: User description: "Multi-tenant SaaS platform targeting Malaysian SMEs with industry-specific modules"

Execution Flow (main)

1. Parse user description from Input
   → If empty: ERROR "No feature description provided"
2. Extract key concepts from description
   → Identify: actors, actions, data, constraints
3. For each unclear aspect:
   → Mark with [NEEDS CLARIFICATION: specific question]
4. Fill User Scenarios & Testing section
   → If no clear user flow: ERROR "Cannot determine user scenarios"
5. Generate Functional Requirements
   → Each requirement must be testable
   → Mark ambiguous requirements
6. Identify Key Entities (if data involved)
7. Run Review Checklist
   → If any [NEEDS CLARIFICATION]: WARN "Spec has uncertainties"
   → If implementation details found: ERROR "Remove tech details"
8. Return: SUCCESS (spec ready for planning)

⚡ Quick Guidelines

• ✅ Focus on WHAT users need and WHY
• ❌ Avoid HOW to implement (no tech stack, APIs, code structure)
• 👥 Written for business stakeholders, not developers

Section Requirements

• Mandatory sections: Must be completed for every feature
• Optional sections: Include only when relevant to the feature
• When a section doesn't apply, remove it entirely (don't leave as "N/A")

For AI Generation

When creating this spec from a user prompt:

1. Mark all ambiguities: Use [NEEDS CLARIFICATION: specific question] for any assumption you'd need to make
2. Don't guess: If the prompt doesn't specify something (e.g., "login system" without auth method), mark it
3. Think like a tester: Every vague requirement should fail the "testable and unambiguous" checklist item
4. Common underspecified areas:
   • User types and permissions
   • Data retention/deletion policies
   • Performance targets and scale
   • Error handling behaviors
   • Integration requirements
   • Security/compliance needs

User Scenarios & Testing (mandatory)

Primary User Story

As a Malaysian SME business owner, I want to access industry-specific business management modules through a subscription-based SaaS platform so that I can streamline my operations without investing in expensive custom software or IT infrastructure.

Acceptance Scenarios

1. Given a new business owner wants to register, When they receive an admin registration link and complete business details, Then the system creates an isolated tenant space pending approval
2. Given an admin approves a tenant registration, When approval is processed, Then the tenant receives credentials and can access subscribed modules
3. Given a retail business user has subscribed, When they access their tenant dashboard, Then they can only use Retail & Food Stall modules based on their subscription plan
4. Given a healthcare clinic has subscribed, When they access the system, Then they can manage patient records, appointments, and billing through their dedicated module
5. Given a business wants to change pricing models, When they request to switch from subscription to perpetual license, Then the system calculates the buyout price based on subscription payments made

Edge Cases

• What happens when a tenant exceeds their subscription module limits?
• How does system handle concurrent access within the same tenant organization?
• What happens if a tenant's subscription payment fails?
• How does system ensure data isolation between tenants during peak usage?
