Introduction to McKinsey Problem Solving

McKinsey’s problem-solving methodology is a structured approach that emphasizes data-driven decision-making and creative solutions. This process involves defining the problem, disaggregating it into manageable parts, conducting rigorous analysis, and synthesizing findings into actionable recommendations. The goal is not only to solve the immediate issue but also to create long-term value for clients.

Does Everyone Get the McKinsey Problem Solving Game?

One common question is whether everyone gets the McKinsey Problem Solving Game (PSG) during the recruitment process. The PSG is designed to assess candidates’ problem-solving skills in a simulated business scenario. While not every candidate may experience the PSG, understanding its principles can still offer valuable lessons for entrepreneurs.
