Editor's Notes
- #9: Create a culture where LOB people and decision makers are communicating
- #14: Wants to show just the middle chart – Jason will send me a better image. Most of this data does not come from SOASTA. But it does speak to the percentage of CBSi stuff vs. other stuff. Move higher in the deck. Comes from sitespeed.io. Takeaway – they only control about 30% of their site.
- #15: Jason will find a better graph here, too. Add Soasta example to deck
- #17: Change to header bidding system (not BeanStock)
