The frequency of conducting a SWOT analysis varies depending on the business's industry, size, and the changes in the market. As a general guideline, businesses should conduct a SWOT analysis at least once a year to evaluate current situation, stay up to date with changes in the industry and adjust strategies accordingly. However, there are some specific moments when a SWOT analysis is necessary, for example, at the launch of a new product, when entering a new market, or when there is a significant shift in the business environment (changes in regulations or market conditions). The frequency of conducting a SWOT analysis should be determined based on the business's unique circumstances and the need to make informed strategic decisions or update them.
