Unit (SBU). The dimension of business strength—relative market share—will
measure comparative advantage indicated by market dominance. The key
theory underlying this is existence of an experience curve and that market
share is achieved due to overall cost leadership.
The BCG matrix has four cells, with the horizontal axis representing rela-
tive market share and the vertical axis denoting market growth rate. The
mid-point of relative market share is set at 1.0. If all the SBUs are in the
same industry, the average growth rate of the industry is used. However, if
all the SBUs are located in different industries, then the mid-point is set at
the growth rate for the economy.
Resources are allocated to the business units according to their situation
on the grid. The four cells of this matrix have been called stars, cash cows,
question marks, and dogs. Each of these cells represents a particular type of
business, as described here:

1. Stars: Stars represent business units having large market share in a fast
growing industry. They may generate cash but because of fast grow-
ing market, stars require huge investments to maintain their lead. Net
cash ow is usually modest. SBUs located in this cell are attractive as
they are located in a robust industry and these business units are highly
competitive in the industry. If successful, a star will become a cash cow
when the industry matures.
2. Cash Cows: Cash cows represent business units having a large mar-
ket share in a mature, slow growing industry. Cash cows require little
investment and generate cash that can be utilized for investment in
other business units. These SBUs are the corporation’s key source of
cash, and are specically the core business. They are the base of an
organization. These businesses usually follow stability strategies. When
cash cows lose their appeal and move toward deterioration, then a
retrenchment policy may be pursued.
3. Question Marks: Question marks represent business units having low
relative market share and are located in a high-growth industry. They
require huge amounts of cash to maintain or gain market share. They
require attention to determine if the venture can be viable. Question
marks are generally new goods and services that have a good commer-
cial prospective. No specic strategy can be adopted. If the rm thinks
it has dominant market share, then it can adopt expansion strategy, or
else retrenchment strategy can be adopted. Most businesses start as
question marks as the company tries to enter a high-growth market in
