Activities:

1. Draw a Context Diagram using the accompanying narrative.

2. Given the accompanying use-case matrix, draw the Event Decomposition Diagram.

Use the following narrative to construct the Context Diagram for the Equipment Check-out System (ECS). The purpose of the Equipment Check-out System is to provide maintenance employees with the equipment needed to complete their maintenance jobs. As they are needed, employee will request equipment to be checked out. The Equipment Depot staff will maintain records of these check-outs and provide the employees with the appropriate equipment and an equipment check-out receipt. When employees have finished with the equipment, the employee must conduct an equipment check-in at the Equipment Depot. In response to the equipment check-in, the Equipment Depot staff will maintain records of the equipment check-in and provide the employee with an equipment check-in receipt. Occasionally, supervisors will make a request to for new equipment that results in the Equipment Depot staff needing to purchase this equipment through equipmentdeals.com, who will send an electronic file showing the status of all orders on a daily basis. This file will be imported into the system so that the Equipment Depot staff can field status requests from supervisors. When the Depot staff receives ordered equipment, they will use the packing slip to verify the shipment and notify the requesting supervisor of their availability. The Safety Committee will periodically submit a list of skill classifications that can safely check-out any piece of equipment. Supervisors will submit the skill classifications for each employee. Upon request the system will generate a report for supervisors showing listing employees having a history of excessive equipment losses or damage. Upon request by the employee, the system will generate a statement detailing what equipment they have checked out and are expected to have in their possession.
