MECE Evaluation of Product Portfolio: Resource Allocation by Matrix of Dead Stock and Hit Products

In sustainable growth of EC business, concentrating limited management resources (human capital, ad budget, inventory assets) on which SKU (Stock Keeping Unit) is critical decision directly linked to operating profit margin. In this article, centering on concept of "MECE (Mutually Exclusive, Collectively Exhaustive)" which is golden rule of logical thinking, we classify product portfolio quantitatively and qualitatively. We explain logical framework to prevent immediate dead stock of stagnant inventory and derive strategic investment in hit products from perspective of senior consultant.

1. Importance of MECE and Logical Structuring in Strategic Analysis

Just confirming transition of sales amount does not show true issues. Creating MECE (Mutually Exclusive, Collectively Exhaustive) in multi-faceted analysis on product axis means dropping all SKUs into logical segmentation (market segmentation). This defines all inventory uniquely as one of "Star with high growth/high profit", "Cash Cow with stable profit", "Problem Child requiring reconsideration", or "Dead Stock candidate to withdraw", enabling logical structuring excluding ambiguous judgment.

2. 4-Quadrant Matrix Classification Method of Product Portfolio

Applying method of PPM (Product Portfolio Management), construct matrix with two axes of "Sales Growth Rate (Marketability)" and "Inventory Turnover/Profit Margin (Efficiency)". With this MECE classification, visualize which products create cash and which products absorb cash.

3. Data-Driven Resource Allocation and Portfolio Optimization

For "Star Products" extracted by analysis, prioritize gradient allocation of RPP ads and search optimization (SEO) to solidify market share. On the other hand, for product groups classified into segment with low efficiency, logic of "selection and concentration" to treat current marketing cost as sunk cost and switch resources to growth area is necessary. With this approach, ROAS (Return On Ad Spend) of entire portfolio is dramatically improved.

4. Scenario for Resolving Stagnant Inventory and Improving Cash Flow

Constant occurrence of stagnant inventory is caused by uncertainty of supply and purchasing plan lacking logical basis. By making monitoring based on MECE routine, detect deterioration of inventory freshness (obsolescence) early. By logically executing early digestion at promotion price or return/disposal judgment as "loss cut", it becomes possible to resolve clogging of cash flow and accelerate next investment cycle.

FAQ

Q. How should optimal evaluation axis be set when classifying products into MECE?
A. Generally, "market growth" and "company's competitive advantage" are set as axes, but in EC business, by using "sales growth rate" and "inventory turnover speed", more effective operational judgment becomes possible.
Q. What is the strategy to promote from "Problem Child" segment to "Star"?
A. When there is growth potential but efficiency is poor, main factors are aggregated into "soaring CPA" or "slump in CVR". It is effective to decompose this into MECE and pinpoint improvement of creative or redefinition of target layer.
Q. I am worried that disposal of stagnant inventory (sale) might damage brand value.
A. Instead of blind all-item sale, by disposing of only SKUs defined as "Dog" based on analysis in limited sales channels or closed environments, you can aim for soundness of inventory while maintaining overall brand equity.

Summary

MECE evaluation of product portfolio becomes powerful weapon to eliminate uncertainty in EC management and realize resource optimization. By visualizing state of all SKUs with objective data and clearly distinguishing "Star Products" to attack and "Stagnant Inventory" to retreat, you can build strong revenue base. First, please start by plotting current sales data on matrix and grasping your company's "current location".
