SWOT analysis is a structured planning method used to evaluate the strengths, weaknesses, opportunities, and threats of a project or business venture. It involves specifying an objective and identifying internal and external factors that help or hinder achieving that objective. Strengths are advantageous characteristics, weaknesses are disadvantages compared to others, opportunities are elements that could be exploited, and threats are potential problems. Identifying SWOTs informs later planning steps to achieve the objective.
