4. Using Porter’s Five Forces model, identify the key issues in the competitive environment
that affect ANN and its rivals. Identify and evaluate the competitive forces that shape the
industry structure. How much opportunity exists for industry players?
If the industry is women’s clothing, some suggestions for a Porter’s Five Forces analysis are
given below. ADDITIONAL READING can be assigned here to augment the assigned
textbook. The 2008 HBR article by Michael Porter “The five forces that shape strategy” is a
good overview of his Five Forces model, providing an update to his classic 1980 book on
Competitive Strategy. AN ADDITIONAL EXERCISE to uncover the current degree of rivalry
between competitors is to have students use Handout A to identify the differences between ANN
and its direct competitors, Coldwater Creek, Chico’s, and Talbot’s. Students should be
encouraged to visit the Yahoo! Finance link to see what the current numbers say, and also to visit
the ANN Investor’s website to see the current press releases and SEC filings.
There is no threat from viable substitutes, and both retail buyers and suppliers lack power.
However, there is high rivalry, and threat of new entrants. As the analysis suggests, the
environment is challenging. Given students are personally familiar with retailing, even average
students will intuitively be able to identify the relative levels of each of the five forces. However,
better students will be able to provide rationale for their assessments. Help students apply the
five forces by drawing a diagram as below, and having students fill in the details. (This diagram
is also available for instructors to provide directly to students, as an Exhibit B at the end of this

Suggested: There are no real substitutes
for a woman’s career wardrobe.
Suggested: The industry has low
concentration with many rivals
competing for market share. Some
roduct differentiation exists, but
a lack of switching costs means
firms will compete to steal
customers.
Suggested: Retail Buyers have many
choices of retailers and clothing lines.
However, many women’s specialty
stores design their own private label
other retailers. Therefore buyers have
little power.
Suggested: At the regional level, entry
is not difficult as a retailer can enter as
small scale with little capital and be
able to find raw materials/suppliers
and target consumers. Likely entry is
from expansion of existing
competitors (similar to what ANN did
with LOFT). However, at a national
level entry is more difficult.
Suggested: Given that there are
many supplier firms and that there
is a lack of differentiation between
them, their power is lowered. Some
switching costs may exist if the
clothing buyer changes suppliers,
but the costs are manageable. Lots
of capacity exists in Asia and
suppliers have few alternative
markets in which to sell their
roducts, reducing their power.
