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.

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.
