According to studies completed by Reeves, Moose and Venema in 2014, which of the following was proven to be true with regards to the BCG matrix?

The 2014 study by Reeves, Moose, and Venema for the Boston Consulting Group (BCG) revisited the classic growth-share matrix. A key finding was that the business environment has become significantly more dynamic than when the matrix was created. This increased dynamism and competition mean that product lifecycles are shorter. Consequently, products and business units now move through the four quadrants (Question Mark, Star, Cash Cow, Dog) much more rapidly than in the past. A 'cash cow' can quickly lose its position, and a 'question mark' can become a 'star' in a fraction of the time it once took.

A. Companies nowadays have more 'cash cow' items than in the past: The study suggests the opposite; the increased market dynamism makes the 'cash cow' position less durable and harder to maintain.
C. There is a higher correlation between share leaders and profit leaders nowadays than in the past: The study explicitly found that the correlation between market share and profitability has been declining over time, weakening a core assumption of the original matrix.
D. There is a longer time between innovation and adoption nowadays than in the past: The increased pace of business and shorter product lifecycles highlighted in the study imply a shorter, not longer, time between innovation and market adoption.

Page 2, Paragraph 3: "Today’s business environment is much more dynamic. Cash cows can become dogs in a fraction of the time they once did. And with the right nurturing, a question mark can become a star in a flash." (Supports correct answer B and refutes A and D).

Page 2, Paragraph 4: "The correlation between market share and profitability has been declining. In many industries, the link is weak or nonexistent." (Refutes incorrect answer C).
