As business models evolve, they tend to have a leaner approach. In this context, a lean industry is meant to focus only on things that have value to the target client of the product. Whatever procedure, part of the product, or process that creates it that does not provide value to the product is considered useless and must be removed or changed so it adds more value to the end-to-end solution. With the same approach, smart business models tend to only have steps that add value and knowledge to the business model, which means that outsourcing is still a big deal in this area. Becoming lean is not easy and cheap if you don't know how to integrate the end-to-end service chain into the business.

Blockchain comes into action when outsourcing or decentralizing business tasks are vital to the model, by giving the opportunity to decentralize tasks. Let's take a look at a traditional car sales process in the following diagram:

Whenever a customer buys a car, a new entry for that car is created in the dealer's ledger and an order is placed to the carmaker, which creates another entry into its ledger and orders parts from its suppliers, and this also creates order entries in their ledgers. Blockchain simplifies the process by using a shared ledger for all stakeholders of the process:

The process itself is now auditable by design and the final product can be tracked end to end, giving the new car's owner knowledge about the origin of the product.

Blockchain enables a product-driven business process that is both lean and auditable.
