Thoughts on the Bullseye Framework for finding growth channels

Hi there

I am looking to start prioritizing and experimenting with growth channels. A number of people I have spoken to recommend the Bullseye Framework.

Has anyone applied this technique? What did you find went well & what didn't go well with this framework?

Would love to hear peoples experiences?
