Private Label Assortment Cannibalization Risk Matrix

Role: Senior CPG Category Product Manager with expertise in retail private label assortment planning and unit economics.

Context

• Retail category under review: {{category_name}}
• Proposed private label product concept: {{store_brand_concept}}
• Incumbent market leaders in this category: {{incumbent_national_brands}}
• Target gross margin improvement: {{target_gross_margin_lift}}
• Historical customer purchase frequency: {{category_purchase_frequency}}
• Elasticity and price differential profile: {{price_elasticity_estimate}}

Task

Construct an assortment cannibalization evaluation framework to determine whether introducing {{store_brand_concept}} into {{category_name}} yields accretive category value without destabilizing national brand partnerships.

Method

1. Establish the baseline substitution risk between {{store_brand_concept}} and {{incumbent_national_brands}} based on {{price_elasticity_estimate}}.
2. Model the gross margin variance per basket required to achieve {{target_gross_margin_lift}} under varying volume shift scenarios.
3. Segment shopper buying behavior according to {{category_purchase_frequency}} to identify brand-loyal versus price-sensitive buyers.
4. Construct a 4-tier risk classification index covering: pure basket accretion, margin-positive cannibalization, zero-sum brand switching, and margin-dilutive trade-down.
5. Define shelf placement, digital discovery, and promotional guardrails to preserve vendor allowances.
6. Formulate kill-criteria and SKU de-listing thresholds based on 90-day velocity targets.

Constraints

• MUST calculate trade-offs using both unit margin and total category gross profit dollars.
• MUST NOT evaluate packaging artwork, manufacturing vendor selection, or supply chain logistics.
• Recommendations MUST preserve healthy relationships with {{incumbent_national_brands}}.
• Framework must be applicable to both brick-and-mortar shelf space and digital catalog merchandising.

Output format

Provide the assessment framework in four sequential sections:

1. Cannibalization Decision Matrix (markdown table showing risk levels, criteria, and margin thresholds)
2. Assortment Placement & Merchandising Guardrails (bulleted operational rules)
3. Category Economic Impact Model (step-by-step projection summary)
4. Product Lifecycle Kill-Triggers (numbered list of quantitative exit metrics)

Self-review

• Ensure all 6 context variables are utilized within the methodology and guardrails.
• Check that gross margin lift targets are balanced against vendor partner risks.
• Verify formatting matches the required four section headers exactly.
