[Problem Solving] Why Sales Are Not Growing? Management Strategy to Pinpoint Root Cause with "3C Analysis" and "Logic Tree"

"Sales don't go up even though I'm increasing shipping costs", "I feel like customers are being taken by competitors, but I don't know exactly what to improve". These management worries are caused by fragmentation of information. To break through wall of sales stagnation, logical thinking based on concept of "MECE (Mutually Exclusive, Collectively Exhaustive)" eliminating intuitive judgment is essential. In this article, combining 3C analysis and logic tree, we explain practical framework to identify true meaning (bottleneck) of sales slump.

1. Logical Background Why "Action-First" Measures Lead to Failure

Trap many companies fall into is "action-first" thinking like "let's strengthen SNS ads for now" or "let's renew site design" when sales drop. However, moving without identifying whether cause lies in "change in market needs (KBF: Key Buying Factors)", "competitor's low price strategy", or "decline in own repeat rate" has to be said as war of attrition without strategy.

By using MECE (Mutually Exclusive and Collectively Exhaustive) which is basis of logical thinking, we organize issues comprehensively and prevent wasting resources on measures with low priority.

2. Extracting "Inconsistency" of Market, Competitor, and Company into MECE with 3C Analysis

First, from macro perspective, verify structure of environment surrounding business.

By analyzing these 3 elements into MECE, clarify gap between "place to fight (market)" and "reason to win (company's strength)".

3. KPI Decomposition by Logic Tree and Identification of Root Cause

Next, from micro perspective, decompose index called "sales". By repeating decomposition using logic tree, "true bottleneck" to be improved is visualized.

For example, sales of EC business can be decomposed into "Visits x Conversion Rate (CVR) x Average Customer Spend". Further decompose "Visits" into "Ad Inflow" and "Organic Search (SEO) Inflow", and verify with data which branch has abnormal value.

4. Priority of Decision Making: Roadmap for Improvement Shown by Data

If logic tree breakdown shows 'Avg Spend' is on target but 'CVR' has dropped clearly, increasing Visits is inefficient. First concentrate resources on UI/UX improvement or offer reconstruction.

Thus, process of "decomposing whole into MECE and identifying bottleneck based on facts (data)" is essence of strategy formulation realizing sustainable growth.

FAQ

Q. Which should I start with, 3C analysis or logic tree?
A. Generally, define "external environment and company positioning" with 3C analysis and determine direction of big strategy. Then, use logic tree to drill down cause of failure to achieve specific numerical targets.
Q. Is there a way to check if MECE decomposition is done?
A. Please check if it matches original number (KGI) when decomposed elements are "added" or "multiplied". By formulating, logical omission or duplication can be eliminated.

Summary

The cause of sales not growing is often complex intertwining of external and internal factors. By looking down at battlefield with 3C analysis and decomposing numbers into MECE with logic tree, "winning move" not relying on intuition becomes visible. Pinpointing true cause behind data is only way to realize sustainable growth.
