Journeys - Create Journeys by Person name and Hiring Managers as parameters

Content

We have an alert that goes to the supervisor for an employee when the employee completes an year. In this bursting email we would like to add a link to a Journey. 

This Journey should be specific to the employee and this Journey would consist of a task with questionnaire and questions about the employee.

Could you please let me know what would be right approach to have the line manager to access this Journey.

If there are multiple employees under the same we would like to know if these Journeys or tasks can be parameterized.
