Business Analysis Standards (Deep Analysis + Story Authoring)

Priority: P0 (CRITICAL)

1. Deep Investigation Protocol

• Atomic AC Decomposition: Split Acceptance Criteria (AC) into 1-Condition logic units (e.g., "User can X and Y" -> "User can X", "User can Y").
• Variable Identification: Extract all Feature Toggles, Market Rules (VN/MY/SG), and User Roles.
• Platform Parity: Verify if logic applies to both Web and Mobile; Flag divergent behavior early.
• Truth Table Verification: Map complex multi-condition logic to Logic Truth Table.

2. Dynamic Actor & Permission Mapping

• Identify all Actors (e.g., Customer, Sales Rep, Admin).
• Use Actor/Permission Matrix to map specific constraints per Actor.
• Permissions Patterns

3. Edge Case & Boundary Analysis

• State Validation: Verify behavior across all entity (e.g., Active, Suspended) and network states.
• Boundary Detection: Analyze currency, date, and count limits.
• Negative Testing: Identify flows for Unauthorized Access, Invalid Input, and Null-safety.

4. Anti-Patterns (Analysis)

• No Surface Reading: investigate implications, don't restate.
• No Assumption: Flag undefined states (e.g., Offline) as P0 blockers.
• No Loose Mapping: Ensure AC aligns 100% with Technical Impact notes.

5. User Story Authoring Standards

• Story Structure: Every story must use As a [Actor], I want [Goal], so that [Value].
• AC Format: Each AC must one Given / When / Then block — one condition per block.
• Platform Tag: Prefix each AC with [WEB], [MOBILE], or [BOTH] — never mix platforms in one AC block.
• Toggle Contract: Each feature flag AC must name flag and state: Toggle: <FlagName> = ON/OFF.
• Market Isolation: Any market-specific AC must prefixed [Market: VN], [Market: MY], etc.
• Scope Fence: Include explicit ## In Scope, ## Out of Scope, and ## Deferred sections. Deferred items must link to Jira ticket — never write "to discuss".
• Translation AC: Language/locale behavior separate AC, not inline note.

See User Story Template for full authoring template.

6. Anti-Patterns (Story Authoring)

• No mixed-platform AC: [MOBILE ONLY] buried inline hides parity gaps — use platform tags.
• No "to discuss": Replace with linked Jira ticket in ## Deferred.
• No implicit toggle states: Always declare both ON and OFF behavior per AC.
• No bundled AC: "User sees X and Y and Z" → split into three separate AC blocks.

7. Validation Checklist

Run after authoring or reviewing any User Story before marking it ready for development:

• Every AC [WEB], [MOBILE], or [BOTH] platform tag
• Every toggle AC declares both = ON and = OFF states explicitly
• No AC block contains more than one And condition (split if it )
• No "to discuss" text anywhere — replaced by Jira link in ## Deferred
• Story ## In Scope, ## Out of Scope, and ## Deferred sections
• Story uses As a / I want / So that header
• Market-specific ACs prefixed [Market: VN], [Market: MY], etc.
• Translation / locale behavior its own AC or deferred with Jira link
