Analysis Quote by Victor Cheng
““If you’re doing the analysis correctly, you are constantly drilling down one branch, discovering it’s not valid, revising your hypothesis (and often the branches of your issue tree), and then drilling down an entirely new branch. You do this over and over, all day long, in both consulting and case interviews. Drill down, pull up, revise the hypothesis, restructure the issue tree, drill down again ... lather, rinse, repeat.””
