Why do you call it the business model? It's the 'payment model for employees'. Some jobs (typically older, simple manufacturing jobs) pay by-item, but that doesn't work for e.g. software. (Paying by the line of code wouldn't work really well, for example). Therefore most jobs where it's difficult to estimate employee's performance fallback to by-hour wages. The business model has nothing to do with how the corporation pays it's employees.
