I am an ex McKinsey consultant and a Columbia Business school alum, let's learn together:

• Structure complex problems to identify the root cause

• Once the problem is set up, look at the individual causes and find relevant and feasible solutions

• Communicate it clearly to get buy in from leadership and peers

Solving the problem is half the battle, communicating the solution and influencing people is the other half

Not just business professionals but Entrepreneurs and business owners like Elon Musk follow First principles thinking and problem solving -
