To achieve economies of scale with digital business models requires the development and reuse of digitized platforms across the enterprise. Without such shared platforms, the IT units in companies implement a new solution in response to every business need , creating a spaghetti - like arrangement of systems that do meet specific customer needs but are expensive and fragile — and don ' t scale enterprise - wide . Worse still, the customer experience suffers as the customer gets a fragmented product - based experience rather than a unified multiproduct experience.
