The additional manager role allows someone other than a person's direct manager in 15Five to write a manager review for them. This can be beneficial when an employee has a dotted-line manager relationship and you want their feedback to be gathered in a review cycle. You can appoint a default additional manager, which allows them to write additional manager reviews in all cycles a person is a participant in, or cycle-specific additional manager, which gives people the ability to write an additional manager review in only a specific review cycle.

Access and availability

📦 This feature is available in the Perform and Total Platform pricing packages.



Additional manager feedback is included in calibration sessions and can be incorporated into the calculation of employee performance ratings.

Add default additional managers

You can assign one default additional manager per employee. A person's default additional manager will be automatically assigned as an additional manager in all review cycles they participate in. Default additional managers can also be granted visibility into all past reviews of the person they're an additional manager for in Best-Self Review® feature settings.

There are two methods for adding default additional managers— using our bulk import tool (best if you want to add additional managers for multiple people at once) or in a person's account settings (best for adding an additional manager for a person one-off).



For a default additional manager to be asked to submit an additional manager review for a participant, they must be appointed before the review cycle launches. Suppose you want a person to write an additional manager review for someone and didn't add them as an additional manager before the cycle's launch. In this case, you can add them as a cycle-specific additional manager.
