Business Analysis Standards (Deep Analysis + Story Authoring)

Priority: P0 (CRITICAL)

Behavior-Based AC Decomposition: Define Acceptance Criteria (AC) around one observable behavior per AC; multiple necessary preconditions are permitted. Do NOT split based solely on the word 'And' or condition counts.
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 interacting conditions to a Logic Truth Table; escalate policy decisions to owners rather than selecting business policy silently.

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.

No Surface Reading: investigate implications, don't restate.
No Unowned Unknowns: Carry confirmed evidence and explicit non-critical assumptions. Consequential undefined states block only affected slices (naming owner, consequence, and required input); preserve PARTIAL readiness boundaries. Sensitive changes require technical design and explicit human/governance approval per requirements modeling §1, not blanket P0 blocking.
Consume shared requirements modeling for preserved stakeholder conflicts, quality review versus need validation, and applicable temporary transition needs; retain existing IDs and only reopen affected slices.
For general BA/elicitation requests requiring confirmation of captured meaning, directly load the BRD-owned analysis and elicitation procedure without requiring brainstorm-feature or full BRD intake. Participant confirmation does not imply approval.
No Loose Mapping: Ensure AC aligns 100% with Technical Impact notes.

Story Structure: Every story must use As a [Actor], I want [Goal], so that [Value].
AC Format: Each AC must use one Given / When / Then block representing one observable behavior; multiple necessary preconditions are permitted.
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.

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: Require applicable ON and OFF coverage across the story AC set; each individual AC names its own state (e.g., Toggle: <FlagName> = ON).
No multi-behavior bundling: Split distinct user actions/outcomes into separate AC blocks; do not split single behaviors with multiple preconditions.

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

Every AC [WEB], [MOBILE], or [BOTH] platform tag
Toggle features cover applicable ON and OFF states across the AC set (each individual AC naming its own state)
Each AC verifies one observable behavior (multiple necessary preconditions allowed; do not split solely on 'And')
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
