Retail & Consumer Goods: Channel Strategy and Format Cases

Prepare for retail channel strategy cases covering format selection, marketplace vs. owned channels, dark stores, and omnichannel portfolio optimization.

Retail channel strategy cases ask you to decide where and how a company should sell — not just what it sells. Based on our analysis of consulting interview patterns, channel and format questions appear in roughly 15% of retail cases, often as a strategic decision overlay on top of profitability or growth strategy prompts.

What Makes Channel Strategy Cases Distinct

Unlike pure profitability cases that focus on margin levers, channel strategy cases force you to evaluate trade-offs between reach, control, economics, and customer experience simultaneously. The interviewer wants to see whether you can reason about a portfolio of channels rather than optimizing one in isolation.

In our experience working with candidates, the most common mistake is treating channels as independent P&Ls. In reality, channels interact — a new DTC website cannibalizes wholesale revenue, a dark store reduces in-store basket size but increases delivery orders. Your framework must account for these cross-channel effects.

The Channel Portfolio Framework

When you encounter a channel strategy case, structure your analysis around four dimensions. This framework applies whether the client is a grocery chain evaluating dark stores or a CPG brand choosing between Amazon and DTC.

Five Common Case Archetypes

1. “Should We Launch DTC?”

A CPG brand currently selling through retailers asks whether to build a direct-to-consumer channel. The key tension is margin improvement versus retailer relationship risk.

What interviewers test: Can you quantify the breakeven customer acquisition cost and model retailer retaliation scenarios?

2. “Which Store Format for Market Entry?”

A retailer entering a new geography must choose between hypermarkets, convenience stores, or online-first. Based on our work with interview cases, this archetype tests your ability to match format economics with local market structure.

What interviewers test: Do you consider population density, income distribution, and competitive saturation before recommending a format?

3. “Marketplace vs. Owned Channel for Growth”

A brand growing at 8% wants to accelerate to 15%. Should it double down on Amazon/marketplace or invest in owned channels? The trade-off is speed versus margin and data ownership.

What interviewers test: Can you model the long-term LTV difference between marketplace customers (low loyalty, no data) and owned-channel customers?

4. “Dark Store / Micro-Fulfillment Viability”

A grocery chain sees 40% growth in delivery orders and must decide between converting existing stores, building dark stores, or partnering with a third-party delivery platform.

What interviewers test: Unit economics analysis — delivery cost per order, throughput capacity, and the impact on in-store experience if converting floor space.

5. “Channel Conflict Resolution”

A brand’s wholesale partners complain that the new DTC site undercuts their pricing. Revenue from wholesale is 70% of total. How do you resolve this without destroying either channel?

What interviewers test: Creative solutions (product differentiation by channel, MAP pricing, exclusive SKUs) and stakeholder management thinking.

Key Metrics You Must Know

Interviewers expect familiarity with channel-specific metrics. In our analysis of 200+ retail cases, candidates who reference these metrics score significantly higher on business judgment:

MetricDefinitionWhy It Matters
Channel contribution marginRevenue minus all channel-specific variable costsCompares true profitability across channels
CAC by channelCost to acquire one customer through a specific channelDetermines channel sustainability
Cross-channel halo effectRevenue lift in other channels when a new channel launchesCaptures synergies often missed
Channel cannibalization rate% of new channel sales that would have occurred elsewherePrevents double-counting growth
Fulfillment cost per orderPick, pack, ship cost varying by channel and formatCritical for delivery/dark store cases

Format Innovation: Emerging Themes

Interviewers increasingly draw on real-world format innovation for case prompts. Based on our tracking of recent consulting project themes:

  • Rapid delivery (10–30 min): Dark stores and micro-fulfillment centers optimized for speed over assortment. Unit economics remain challenging — most operators lose $3–5 per order at current density.
  • Hybrid formats: Stores serving dual purposes (retail + fulfillment hub). Reduces last-mile cost by 30–40% compared to dedicated dark stores.
  • Unmanned / automated stores: Reduced labor cost by 60–70%, but limited to high-traffic urban locations with low shrinkage risk.
  • Social commerce: Live-streaming and community group-buying channels growing at 35%+ annually in Asia-Pacific markets.

Structuring Your Answer

When you get a channel strategy prompt, open with this sequence:

flowchart TD
    A[Clarify the client's objective] --> B[Map current channel portfolio]
    B --> C[Identify the gap or trigger]
    C --> D{What type of decision?}
    D -->|Add new channel| E[Economics + Fit + Cannibalization]
    D -->|Optimize existing| F[Margin drivers + Reallocation]
    D -->|Resolve conflict| G[Root cause + Creative solutions]
    E --> H[Recommendation with trade-offs]
    F --> H
    G --> H

Opening question suggestions (to ask the interviewer):

  1. “What’s the current channel mix by revenue contribution?”
  2. “Is the primary objective revenue growth, margin improvement, or customer reach?”
  3. “Are there existing contractual obligations with channel partners?”

Key Takeaways

  • Channel strategy cases test portfolio thinking — never analyze one channel in isolation without considering cross-channel effects
  • Lead with economics (contribution margin, CAC, cannibalization) before discussing qualitative factors like brand control
  • Format innovation cases require unit economics fluency — know the cost structure of dark stores, micro-fulfillment, and last-mile delivery
  • Channel conflict cases reward creative solutions (exclusive SKUs, differentiated pricing, bundled services) over zero-sum thinking
  • Always ask about the time horizon — a channel unprofitable in year one may generate 3x returns by year three through data and loyalty effects
