Managers
The only people who should be managers are those that you consider eligible to approve risks. In BS:7858, this is called 'top management' and generally refers to the senior leadership team. You are able to add people outside of the SLT, but you may need to prove to your auditors that they have received consent to approve risks.
Managers also have all permissions in Deploi. They are able to amend any processes and add new users and candidates.
