About this skill

What problem it solves

When planning a multi-product portfolio, teams often have business lines, sales, market share, and growth rates, but lack a clear decision framework. This skill turns the BCG Boston Matrix into a structured analysis workflow: classify each business as a star, cash cow, question mark, or dog, then map it to build, hold, harvest, or divest strategies with resource-allocation priorities.

How it works

Structured input: requires fields such as analysis_object, business_units, growth_threshold, and share_threshold, using the business format name,sales,relative market share,growth rate(%).
Standard BCG analysis: positions each unit by market growth and relative market share, with adjustable thresholds and optional four-rule portfolio health checks.
Decision-oriented output: includes quadrant classification, strategy actions, and investment priorities; extended mode can add a GE matrix or Grand Strategy matrix for multi-factor strategy evaluation.
Case references: includes Rongshida Group and a confectionery case to illustrate cash-cow funding, selective investment, and portfolio lifecycle logic.

Boundaries and caveats

BCG is a simplified planning model, not a precise financial forecast. It is useful for portfolio diagnosis and strategy ranking, but thresholds should be calibrated to the industry. For strongly differentiated businesses, capital-intensive operations, or decisions requiring broader market and competition factors, combine it with GE matrix analysis, competitive analysis, or financial modeling.
