If a kite got stuck in a tree, some of the constraints to solving the problem might include:

• the length of the tail on the kite

• the type of kite it is

How might the type of material the kite is made out of affect the solution?

• If it is strong material, it would never tear.

• If it is cheap material, it would tear easily.

• It would tear no matter what.

• The material type doesn't matter.

Sometimes parts of different solutions can be combined. What benefit(s) does this offer?

• It allows for the best part of each to be used in the final solution.

• It allows for test variables to be tested.

• It allows for the designers to meet customer demands.

• It allows for a solution that is better than earlier solutions.
