How engineers define problems?

• Solutions are separate from engineering

• Solutions are the technology all around us.

• Solutions must be complicated in order to work.

• Solutions does not meet a want or need.

Which statement is true of solutions?

• Solutions are the technology of a problem.

• Solutions are the limitations of a problem.

• Solutions can be tested.

• Solutions do not meet a want or need
