Purpose

The purpose of this discussion is to reflect on your knowledge of functional decomposition, and to encourage deeper

understanding of functional flows in consumer products.

The Work

Role-play that you are either a signal, energy, or material flow of a consumer product of your choice (that has at least ten subfunctions).

Describe, in first-person language and complete sentences, your journey as the functional flow from start to finish.

• What form do you take as an input to the system?

• What subfunctions translate your flow into different flow types?

• Are there any functional flow losses caused by any subfunctions in the system?

• What form do you take as an output from the system?
