You're not limited to your own organization when it comes to requesting feedback. You can also request feedback from outside sources, such as customers, business partners, etc...

How do I request external feedback?

Click on the Feedback button in the main menu. In the feedback window, click on Feedback Request. 

To ask feedback from an external person, just enter their email address in the 'receivers' search bar. That person will then receive an email with your message and a request for feedback.

What does the external person need to do?

They will receive an email like this:

They should click on the link or the button to give feedback. No login required.

Afterwards, they get this screen where they can write their feedback. The core values and skills you tagged are also visible for this person.

How will the feedback look like on your feed?

If the external person gave you feedback it will appear on your feed. 

You can always comment on the feedback you received. You have the option to send your comment to the external person.
