Question 1

What is product portfolio management?

Accepted Answer

The practice of managing a company’s entire collection of products as a coordinated whole, allocating finite resources across them to maximize the success of the overall business rather than any single product.

Question 2

Why does product portfolio management matter?

Accepted Answer

Because resources are finite, and without a portfolio view they get allocated by politics and inertia, leaving strong products underfunded and weak ones draining resources.

Question 3

What is the BCG matrix?

Accepted Answer

A portfolio tool from the Boston Consulting Group, popularized by its founder Bruce Henderson in a 1970 essay, that plots products on two axes, relative market share and market growth rate, into four quadrants.

Question 4

What are the four quadrants of the BCG matrix?

Accepted Answer

Stars (high share, high growth), Cash Cows (high share, low growth), Question Marks (low share, high growth), and Dogs (low share, low growth), each with a distinct strategy.

Question 5

What is a Cash Cow?

Accepted Answer

A high-share product in a mature, low-growth market that generates more cash than it needs. The strategy is to harvest that cash and use it to fund stars and promising question marks.

Question 6

What is a Star?

Accepted Answer

A high-share product in a high-growth market. Stars are winners that usually need heavy investment to sustain leadership, and are meant to become tomorrow’s cash cows as their markets mature.

Question 7

What should you do with a Dog?

Accepted Answer

Usually divest or wind it down to free the resources it consumes, though a dog that still generates steady cash or serves a strategic purpose may sometimes be kept.

Question 8

What is the real logic behind the BCG matrix?

Accepted Answer

A cash-flow engine: cash cows fund stars and selected question marks, stars mature into future cash cows, and dogs are pruned. Balance across the quadrants is the point.

Question 9

What are the limits of the BCG matrix?

Accepted Answer

It reduces a product to just two dimensions, ignores profitability and synergies, depends heavily on how the market is defined, and was built for stable markets, so it is a starting lens, not a final answer.

Question 10

How is portfolio management different from managing a product?

Accepted Answer

Managing a product optimizes one product; portfolio management optimizes the mix, deciding how finite resources should be allocated across all products for the good of the whole business.
