SWOT Analysis

Strengths

A firm's strengths are its resources and capabilities that can be used as a basis for developing a competitive advantage. Examples of such strengths include:

• patents
• strong brand names
• good reputation among customers
• cost advantages from proprietary know-how
• exclusive access to high grade natural resources
• favorable access to distribution networks

Weaknesses

The absence of certain strengths may be viewed as a weakness. For example, each of the following may be considered weaknesses:

• lack of patent protection
• a weak brand name
• poor reputation among customers
• high cost structure
• lack of access to the best natural resources
• lack of access to key distribution channels

In some cases, a weakness may be the flip side of a strength. Take the case in which a firm has a large amount of manufacturing capacity. While this capacity may be considered a strength that competitors do not share, it also may be a considered a weakness if the large investment in manufacturing capacity prevents the firm from reacting quickly to changes in the strategic environment.

Opportunities

The external environmental analysis may reveal certain new opportunities for profit and growth. Some examples of such opportunities include:

• an unfulfilled customer need
• arrival of new technologies
• loosening of regulations
• removal of international trade barriers

Threats

Changes in the external environmental also may present threats to the firm. Some examples of such threats include:

• shifts in consumer tastes away from the firm's products
• emergence of substitute products
• new regulations
• increased trade barriers
