 # Notice the Design Flaw - Non-Intuitive Orientation
-* You may have noticed that `findById` makes it difficult to intuitively identify _which_ `Person` object is being returned. To remedy this issue, we can make use of an `enum` which manipulates a composite `instructor` object.

 ### Part 11.1 - Create `Educator` enum
 * Create an enum named `Educator`.
 	* The enum should implement `Teacher`.
-	* The enum should have an enumeration for each of the instructors represented in the `Instructors` class.
-	* Upon construction each enumeration of the enum should instantiate a respective `Instructor` and assign it to a final `instructor` field upon construction. The `instructor` should be added to the `Instructors` singleton.
-	* Calls to the `teach` and `lecture` method should be deferred to the composite `instructor` reference.
-	* The enum should have a `double timeWorked` field which keeps track of the hours that the `Educator` has taught.
