Omnichannel Real-Time Inventory Visibility Specification

Role: Principal Product Manager, Omnichannel Retail Systems

Context

• Brand and operating context: {{retailer_brand}}
• Digital and physical touchpoints in scope: {{channel_scope}}
• Backend data feed and refresh frequency: {{inventory_sync_cadence}}
• Primary customer shopping friction: {{customer_pain_point}}
• Point-of-sale and ERP infrastructure: {{pos_system_architecture}}
• Performance and availability target: {{target_sla}}

Task

Produce a functional product specification document detailing the end-to-end user flows, business logic, edge-case handling, and API integration contracts for displaying real-time store and warehouse inventory levels to shoppers across {{retailer_brand}} touchpoints.

Method

1. Map the inventory state taxonomy across available, low stock, reserved, and out-of-stock statuses tailored to {{channel_scope}}.
2. Translate the latency constraints of {{inventory_sync_cadence}} into user-facing timestamping and confidence indicators.
3. Formulate the core business rules for safety stock buffering and store-level reservation locks based on {{pos_system_architecture}}.
4. Design the primary shopper discovery flow from product detail page through store selector and cart validation.
5. Detail the store associate reserve-and-pick validation workflow to mitigate {{customer_pain_point}}.
6. Specify fallback behavior, cached state degradation, and error messaging when {{target_sla}} is breached.
7. Define telemetry events, inventory accuracy measurement metrics, and downstream analytics hooks.

Constraints

• MUST express all business logic as deterministic IF/THEN/ELSE conditional rules.
• MUST NOT prescribe proprietary third-party UI component libraries or vendor-locked SDKs.
• Technical integration points MUST reference {{pos_system_architecture}} data formats.
• Every edge case MUST include both a user-facing visual state and an associate override action.
• Total output must remain between 400 and 700 words.

Output format

1. Feature Overview & Objectives
2. Inventory State Definitions (table with State, Business Rule, Storefront Label)
3. Core Functional Requirements (FR-1 through FR-6)
4. Edge Cases & Degradation Logic
5. Success Metrics & Telemetry Specification

Self-review

• Verify that safety stock threshold rules directly account for {{inventory_sync_cadence}} delay.
• Confirm all touchpoints identified in {{channel_scope}} have explicit UI status mapping.
• Ensure no unreferenced external variables or placeholders exist in the final text.
