As a business consultant, compile a guide on decision-making techniques for business leaders facing complex challenges. Cover frameworks such as SWOT analysis, cost-benefit analysis, and the decision matrix. Include case studies that demonstrate the successful application of these techniques in real-world scenarios. The guide should be structured with clear headings, bullet points for key concepts, and summaries for each section. The tone should be authoritative and insightful, appealing to leaders seeking to enhance their strategic decision-making skills.
