Official financial segments often reflect bureaucracy, not true business economics. By creating a 'Shadow P&L' through deductive analysis, investors can uncover massive hidden costs in non-core initiatives, as ValueAct did with Microsoft's hardware divisions.

Focusing on "bad to great" is more effective than "good to great" when scaling. Bad behaviors and destructive norms are so corrosive that they make it impossible for excellence to take root. A leader's first job in a turnaround or scaling effort is to eliminate the bad—like dirty bathrooms or incompetent employees—before trying to implement the good.

A common activist trap is 'ambulance chasing'—looking for problems to fix. ValueAct argues the correct sequence is to first identify a great company with a differentiated investment thesis. The need for influence is secondary, preventing adverse selection.

When a business is struggling with multiple revenue streams, the best strategy is to simplify. By cutting underperforming or noisy channels, you can amplify your focus on the one or two profitable areas. This distillation creates the clarity needed to stabilize and eventually rebuild the business.

Rapidly scaling companies can have fantastic unit economics but face constant insolvency risk. The cash required for advance hiring and inventory means you're perpetually on the edge of collapse, even while growing revenue by triple digits. You are going out of business every day.
