Michael Porter’s
  Five Forces
     Model
Michael Porter …

“An industry’s profit potential
 is largely determined by the
 intensity of competitive
 rivalry within that industry.”
Porter’s Five Forces
Portfolio Analysis …
… Strategy at the time (1970s)
 was focused on two dimensions
 of the portfolio grids …
… Industry Attractiveness
… Competitive Position
Business Strength Matrix
Where was
Michael Porter
coming from?
School of Economics …
         … at Harvard …
… Exposed  Porter to the
Industrial Organization (I0)
sub-field of Economics.
Structural reasons why …
… some industries were profitable
* Firm concentration
  * Established cost advantages
    * Product differentiation
      * Economies of scale
Structural reasons …
… all represented barriers to
   entry in certain industries,
   thus allowing those
   industries to be more
   profitable than others.
But Economists …
… generally concerned them-
 selves with the minimization
 rather than maximization of
 what they viewed as excess
 profits (i.e., Public Policy).
Business policy objective
      … of profit maximization
Porter developed his elaborate
framework for the structural
analysis of industry attractive-
ness within the framework of
Business Policy.
Michael Porter …
By using a framework rather than
a formal statistical model, Porter
                     model
identified the relevant variables
and the questions that the user
must answer in order to develop
conclusions tailored to a particular
industry and company.
Porters Five Forces …
* Threat of Entry
 * Bargaining Power of Suppliers
   * Bargaining Power of Buyers
    * Development of Substitute
        Products or Services
      * Rivalry among Competitors
Barriers to Entry …
… large capital requirements or the
    need to gain economies of scale
    quickly.
… strong customer loyalty or strong
    brand preferences.
… lack of adequate distribution
 channels or access to raw materials.
                             materials
Power of Suppliers …
                    … high when
* A small number of dominant, highly
    concentrated suppliers exists.
* Few good substitute raw materials or
    suppliers are available.
* The cost of switching raw materials
    or suppliers is high.
Power of Buyers …
                      … high when
* Customers are concentrated, large or
                 concentrated
    buy in volume .
* The products being purchased are
    standard or undifferentiated making it
    easy to switch to other suppliers.
* Customers’ purchases represent a
    major portion of the sellers’ total
    revenue.
Substitute products …
… competitive strength high when
* The relative price of substitute
    products declines .
* Consumers’ switching costs decline.
                                 decline
* Competitors plan to increase market
 penetration or production capacity.
                             capacity
Rivalry among competitors
            … intensity increases as
* The number of competitors increases
    or they become equal in size.
                               size
* Demand for the industry’s products
    declines or industry growth slows.
                                   slows
* Fixed costs or barriers to leaving the
    industry are high.
                 high
Summary …
As rivalry among competing
firms intensifies, industry
      intensifies
profits decline, in some
        decline
cases to the point where an
industry becomes inherently
unattractive.
unattractive
The Experience Curve …
      … as an entry barrier
Unit costs associated with
economies of scale, the learning
curve for labor, and capital-labor
substitution decline with
“experience,” and this creates a
 experience
barrier to entry, as new competitors
           entry
with no “experience” face higher
costs than established ones.
However …
… If a new entrant has built the
   newest, most efficient plant, it
   will not have to “catch up.”
                           up
… Technical advances purchased
   by new entrants – free from the
   legacy of heavy past Investments –
   may provide those companies a
   cost advantage over the leaders.
In addition …
The experience curve barrier can be
nullified by product or process
innovations that create an entirely
new experience curve – one to
which leaders may be poorly
positioned to jump, but to which
               jump
new entrants can alight as they
enter the market .
Strategic Groups …
Firms that face similar threats or
opportunities in an industry but
which differ from the threats and
opportunities faced by other
sets of firms in the same
industry (e.g., in the beverage
industry: soft drinks group
versus alcoholic beverages).
Strategic Groups …
Rivalry generally is more
intense within strategic groups
than between them because
members of the same group
focus on the same market
segments with similar products,
                       products
strategies and resources.
