The way manufacturing has become industrialised provides a number of parallels with today's IT industry. For example, the manufacturing of cars has evolved so that suppliers' specialisations are maximised. Each supplier delivers their particular component to the final supplier or integrator, who pieces everything together.
The cost of each component is completely transparent as is the business outcome - the car itself.
The IT industry is moving in the same direction. Outsourcing is becoming less tailored to individual organisations and providers are offering more standardised plug-and-play services.
