Typical case of code providing policy instead of mechanism, the solution of course being to provide policy over numerous classes, rules engines, etc instead of writing a few methods that provide mechanism. eg. Why is this method concerned with whether the notification is email or something else... Are persons not also the case of a group with one member? It seems less like refactoring and more like hiding complexity in frameworks.
