Porter's Five Forces
- Threat of New Entrants
- Greatest where there
are low barriers to entry
- New entrants may
already be active in a
similar market sector, but
in a different geographic
market. The threat
becomes a reality if they
try and expand into your
geographic market
- E.g. Budget airlines
expanding into new bases
and therefore taking over
existing routes
- New entrants may arrive
from outside the industry
- Threat of Substitute Products
- Likely to emerge from
alternative technologies
- Substitutes may change the whole economics
of an industry and threaten the survival of
manufacturers of the traditional product
- E.g. typewriters taken over by
PCs. Almost non-existant now
- E.g. sugar manufacturers threatened
by new artificial sweeteners
- Intensity of Rivalry between Competing Firms
- May be high if two or more firms are fighting for
dominance in a fast-growing market
- E.g. early mobile phone market
- May be a fight to establish
dominant technology
- E.g. Blu-ray Vs HD-DVD
- Companies are likely to
engage heavily in promotional
activity involving advertising and
promotional incentives to buy
- In mature industries
(especially with fixed costs
and excess capacity), the
intensity of competitive
rivalry may be very high
- The Power of Suppliers
- Likely to be high if the number of suppliers
is small and/or the materials, components,
and services they offer are in short supply
- The Power of Buyers
- Likely to be high if there are relatively few
buyers, if there are many alternative
sources of supply, and if buyers incur only
low costs in switching between suppliers
- E.g. grocery shopping
