“Most companies owe their initial success to a unique strategic position involving clear tradeoffs….the passage of time and the pressures of growth, however, led to compromises that were at first almost imperceptible. Through a succession of incremental changes that each seemed sensible at the time, many established companies have compromised their way to me-too activities just like their rivals…Through incremental additions of product varieties; incremental efforts to service new customer groups; and emulation of rival’s activities; the existing company loses its clear competitive position.”

– Michael Porter
