Apply BCG Growth-Share Matrix to analyze a product or business unit portfolio for resource allocation decisions.

  • Works in 5 steps: Define the Portfolio Units → Gather Data for Each Unit → Plot on the Matrix → …
  • The user needs to prioritize investments across multiple products
  • SKILL.md covers Overview, When to Use, Framework and Output Format, plus 3 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Biz Bcg Matrix is an agent skill from asgard-ai-platform/skills. Apply BCG Growth-Share Matrix to analyze a product or business unit portfolio for resource allocation decisions. Use this skill when the user needs to prioritize investments across multiple products, decide which products to grow vs harvest vs divest, or evaluate a portfolio's balance — even if they say 'which products should we invest in' or 'portfolio strategy' without naming BCG.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `examples/sample_scenario.md`, `references/framework-comparison.md` and `references/ge-mckinsey.md`).

The repository describes itself as: 301 open-source coding agent skills across 22 domains — methodology, judgment & gotchas packaged as Claude Agent Skills for the Asgard AI Platform. The licence is MIT.

When your agent uses it

  • The user needs to prioritize investments across multiple products
  • Decide which products to grow vs harvest vs divest
  • Evaluate a portfolios balance — even if they say which products should we invest in
  • Portfolio strategy without naming BCG

Example prompts

  • “s balance — even if they say”
  • “portfolio strategy”
  • “/biz-bcg-matrix”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Define the Portfolio Units
  2. Gather Data for Each Unit
  3. Plot on the Matrix
  4. Determine Strategy per Quadrant
  5. Assess Portfolio Balance

What it can do on your machine

Read from SKILL.md and the folder at commit 4e7f4f8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Biz Bcg Matrix loads about 1.7k tokens when it runs, and up to ~6.4k if it reads all its reference files. Until then it costs about 100 tokens; SKILL.md has 628 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~100
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~6.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

BCG Growth-Share Matrix

Overview

The BCG Matrix classifies products or business units into four quadrants based on market growth rate (Y-axis) and relative market share (X-axis). It guides resource allocation: where to invest, where to harvest cash, and what to divest.

When to Use

Trigger conditions:

  • User managing multiple products or business units and needs to prioritize
  • User asks "which products should we invest in vs cut?"
  • User needs a portfolio-level view of their business
  • User mentions "cash cow", "star product", or "portfolio strategy"

When NOT to use:

  • For single-product strategy → use SWOT or Blue Ocean
  • For industry-level analysis → use Porter's Five Forces
  • When detailed financial modeling is needed → use DCF or financial ratios

Framework

IRON LAW: Relative Market Share, Not Absolute

The X-axis is RELATIVE market share = your share / largest competitor's share.
A company with 20% share in a market where the leader has 40% = 0.5x (Low).
A company with 20% share where the next largest has 10% = 2.0x (High).

NEVER use absolute market share. A 30% share means nothing without knowing
the leader's share.
IRON LAW: Plot THEN Strategize

Place ALL products/units on the matrix BEFORE deciding strategy.
Portfolio balance matters — a company with only Stars has a cash crisis
(Stars consume cash). A company with only Cash Cows has no growth pipeline.
Step 1: Define the Portfolio Units

List all products, product lines, or business units to analyze. Each must be:

  • A distinct unit with its own market and competitors
  • Measurable in terms of revenue, market share, and market growth
Step 2: Gather Data for Each Unit

For each unit, determine:

  • Market growth rate: Annual growth rate of the total market (not your revenue growth). Typically, >10% = High growth.
  • Relative market share: Your market share ÷ largest competitor's market share. >1.0x = High.
Step 3: Plot on the Matrix
High Relative Market ShareLow Relative Market Share
High Market Growth⭐ Stars — High share in growing market. Generate revenue but consume cash to maintain position.❓ Question Marks — Low share in growing market. Need heavy investment to gain share, or divest.
Low Market Growth🐄 Cash Cows — High share in mature market. Generate surplus cash with low investment needed.🐕 Dogs — Low share in slow market. Minimal cash generation, limited potential.
Step 4: Determine Strategy per Quadrant
QuadrantDefault StrategyNuance
StarsInvest to maintain/grow shareWill become Cash Cows as market matures
Cash CowsHarvest — maximize cash extraction with minimal investmentFund Stars and selected Question Marks
Question MarksSelective invest OR divest — pick winners, cut losersMost critical decision — not all can become Stars
DogsDivest or repositionMay keep if synergies with other units exist
Step 5: Assess Portfolio Balance

Check the overall portfolio health:

  • Healthy: Mix of Cash Cows (funding) + Stars (growth) + 1-2 Question Marks (pipeline)
  • Unhealthy: All Cash Cows (no growth), all Stars (cash drain), all Dogs (declining)

Output Format

# BCG Matrix Analysis: {Company/Portfolio}

## Portfolio Units

| Unit | Revenue | Market Growth | Rel. Market Share | Quadrant |
|------|---------|--------------|-------------------|----------|
| {Product A} | {$X} | {X%} | {X.Xx} | Star/Cash Cow/QM/Dog |

## BCG Matrix Placement

| | High Share (>1.0x) | Low Share (<1.0x) |
|---|---|---|
| **High Growth (>10%)** | ⭐ {list Stars} | ❓ {list Question Marks} |
| **Low Growth (<10%)** | 🐄 {list Cash Cows} | 🐕 {list Dogs} |

## Strategic Recommendations

### Stars — Invest
- {Product}: {specific investment recommendation}

### Cash Cows — Harvest
- {Product}: {how to maximize cash extraction}

### Question Marks — Decide
- {Product}: Invest / Divest — {rationale}

### Dogs — Divest/Reposition
- {Product}: {recommendation}

## Portfolio Health Assessment
{Overall balance evaluation and rebalancing recommendations}

Correct Application

Scenario: BCG for a Taiwanese electronics company with 4 product lines

UnitMarket GrowthRel. ShareQuadrantReasoning
Laptop line3%1.8x (leader)Cash Cow ✓Mature market, dominant position
Gaming peripherals18%0.4xQuestion Mark ✓Fast-growing but small player
Server components12%1.2xStar ✓Growing market, leading position
Feature phones-2%0.3xDog ✓Declining market, minimal share

Strategy: Harvest Laptop cash → fund Server (maintain Star) + selective invest in Gaming (Question Mark with potential). Divest Feature phones.

Incorrect Application

Scenario: Same company

What went wrong:

  • Used absolute market share (25%) instead of relative (25% / leader's 30% = 0.83x) → Would misclassify as High Share when it's actually Low. Violates Iron Law.
  • Decided "invest in everything" without plotting first → No portfolio trade-off analysis. Violates Iron Law: plot then strategize.

Gotchas

  • Market growth ≠ your revenue growth: A product growing 20% in a market growing 25% is losing share. Use market growth rate, not company revenue growth.
  • Relative share threshold: The 1.0x cutoff is a guideline. In fragmented markets with no clear leader, adjust the threshold. Document your reasoning.
  • BCG is a snapshot: Markets evolve. Stars become Cash Cows, Question Marks become Dogs. Reassess annually.
  • BCG ignores synergies: A "Dog" that provides key components to a "Star" may be worth keeping. Factor in cross-unit dependencies.
  • Not all Question Marks can be funded: The hardest decision. Use additional criteria (market fit, team capability, strategic importance) to choose which to invest in.
