It can be helpful to look at this model to illustrate the cost structure of the different designs a circular product goes through in its total lifetime.
By looking at the current costs structure in the different PLC Phaces it is possible to spot the opportunities to use different alternative approaches to make the product even more circular in the alternative cost structure.

This way we can try out different methods in each redesign, and for some circular products even in each production batch, to see what alternatives give the most circularity at the lowest cost.
Using this model, we can generate different product alternatives; each one includes various sets of circular improvement options in each process. Once the alternatives have been generated, we will evaluate our probability of successfully developing them, the capacity to assume the development effort they require and, finally, the expected market impact of each alternative. With all this information at hand, we will choose the most appropriate circular alternative for the evolution of our product.
