S refers to the advantages inside the enterprise, W refers to the disadvantages inside the enterprise, O refers to the opportunities outside the enterprise, and T refers to the threats outside the enterprise. Therefore, SWOT analysis is actually a method to synthesize and summarize the internal and external conditions of enterprises, analyze the strengths and weaknesses, opportunities and threats faced by enterprises, and then help enterprises make strategic choices.
