Question

What is the input, conversion, and output of operating a summer band camp?

Answer 1

Input is the object, the material, the information, land, equipment, money, knowledge we  fed into a process. 
Output is the created product (good or service) that provide added value to customers. And the process that makes conversion from the input into the output is the operations management.
In our case the final product is operating a summer band camp. The input are materials, buildings (where the camp will be located), hiring staff, but also non-material things -advertising for example. The conversion is rebuilding, interviewing staff.. and the output is opened summer band camp, satisfied customers and hired staff .
