System Interaction
System interaction takes place when multiple systems have to work together in a process or within a product.
Process Example: manufacturing food products
Includes mixing, forming, cooking, cooling, packaging, etc.
Product Example: a bicycle
Includes gear system, braking system, steering system, etc.
Help students to find and discuss other relevant examples.
