Business consulting models provide structured frameworks that help organizations tackle challenges and optimize performance. Key models include the McKinsey 7-S Framework, which aligns internal elements for strategic coherence; SWOT Analysis, identifying strengths, weaknesses, opportunities, and threats; Porter’s Five Forces, assessing industry competition; the Business Model Canvas, visualizing business structure and value creation; and Lean Six Sigma, focused on process improvement and waste reduction. Each model offers a unique approach to problem-solving, enabling consultants to diagnose issues, develop strategies, and drive sustainable growth within organizations.
