Your solution to productivity and effectiveness is an employee training plan. How do you get your new employees competent and expert in their new job? Do you have a plan when you make a new hire, that shows how you'll train them to your new role? You need to demonstrate confidence and competence when you make a new hire, and part of that is knowing how to train them in their new job, beyond having them sit with the current employee and following along. Have a training schedule, with your lesson plans and objectives, as well as how you'll evaluate learning.
