Strengths and weaknesses are internal aspects. This means that they are within the control of the business. They may refer to aspects of marketing, finance, manufacturing or organisation. Opportunities and threats are external factors. This means that they are outside the control of the business. These may include the environment, the economic situation, social changes or technological advances, such as the internet.
A business can create opportunities and counter threats by making the most of its strengths and addressing its weaknesses. For example, one of IKEA's key strengths is its strategic aim to use no more material than necessary in the production of each item. In addition, it develops its product plans to increase its use of waste or recycled materials.
