Problem 1: Use case and requirements 

The following is an example use case diagram for this Exercise. Note that all the use cases specifically requested relate to the Line Supervisor actor. Some additional use cases have also been included in the diagram that relate to other actors. These are either described or implied in the interview transcript, but use case descriptions are not given here. Generate use case descriptions for the use cases listed in the Production Line Control boundary.

Problem 2: Object Modeling

Draw a domain model to fit the following description in the space at the bottom of this sheet.

Hint: use a pencil and an eraser. Or a black/white board with chalk. Draw incomplete boxes.
