A customer has contacted you to help him alleviate a large amount of time and effort that goes into adding and removing users who require access to a business productivity suite. The suite of applications includes word processing, spreadsheet, presentation, and email. Each time an employee is hired, a technician spends over an hour preparing a computer for the user.
