Leslie Snow manages a team of five help desk operators. The cubicles of the operators are located a floor below Leslie's office. Each operator is required to log help desk calls into a team database.

This database tracks the nature of a problem, the length of the call, and whether the problem was fixed or sent to the engineering department for further investigation.

Leslie has a busy schedule, and it is not possible for her to monitor the performance of her team members sitting on a different floor. Therefore she decides to assess their performance solely on the basis of reports queried from the database.
