Support should be based on ensuring the new employee can perform well and create connections, don’t waste it all on admin tasks. In terms of pre-onboarding, you can have them already registered on your systems, and have a welcome video sent to them and their initial schedule. Also notifying the rest of the team about them helps them feel more at ease and ready for their first day.
Once they have met the team it is vital for them to grow and learn whilst receiving feedback from a range of staff in the organisation. Once the onboarding process is complete you should be able to measure how well you’ve done, both for you and the employee and find out what needs to be improved.
