A successful on-boarding process ensures that a new employee is able to deliver top performance (creating value) at your company as fast as possible.
A successful new employee on-boarding process starts before the new employee is due to arrive and it is a structured process vs an afterthought. Some HR platforms include an on-boarding module which supports communication with the expected new employee and key stakeholders at the company who play a role in the on-boarding process. On-boarding activities can include training to be completed, forms that need to be finalized and submitted etc. Coordinating all of these activities and documenting the on-boarding plan is often the responsibility of HR.
This template is a basic version and you should add your own additional items to help new employees understand your industry, office building and business better. If the new employee will be in a customer-facing role you may need to include introductions to customers too.
I would say the signing off by the manager and new employee is optional – depends on your company culture and how you would prefer to run things at your office. The important part is THAT you have a structured process to bring someone new into the company and that this process is run in a consistent manner. That way you can be sure that each new employee has received all of the support needed to as quickly as possible understand the way things are done at your company and who to talk to about specific topics and ideas. This is a vital part of ensuring the newly hired employee gets to the top of their performance potential in the shortest possible time period and feel welcome – engaged – from day 1.
