Position:
When an employee is assigned to a position on the employee record, all information defined for that position default on the record.  For example, say there is an organization with a volunteer position that has high turn over.  Instead of having to add the information to the employee record for that position every time there is a new employee, the position will load the default information reducing time spent on data entry. 

Track:

Consider a track a process made up of steps. You can define checklist items for each step in the process. For example, the new hire process requires that new employees complete several payroll forms. You can define a New Hire Payroll track with checklist items for Complete W-4 form, Complete I-9 form, and Complete Direct Deposit Form.

You can designate when to add a track to an employee record and when to add each checklist item within the track. You can set up a track to automatically update an employee’s status information and add another track upon completion of the track. You can also associate actions with each checklist item and track. For example, if you have a track for the interviewing process, you can add a checklist item to the track to interview the applicant. You can also add an action to the checklist item so that when the interview is complete, you are automatically reminded to schedule a meeting to make a decision about the applicant.
