Jodi's Planning Template

https://bit.ly/2mqVzmJIf you're following the thread, you'll see that I really like Jackie's template and used it recently with a new client. So to add to the conversation, I created a template that demonstrates what I consider when I am thinking about an individual slide and how I will set it up.
Before this stage I always develop a creative brief (objectives, audience essentials, tone, style requirements like fonts and colors, graphic libraries) and then I always have a high level outline or structure that looks like a story flow. But this template articulates what I would think about for individual slides and what choices or decisions I would be making.
Hope it helps! My best advice would be to start with Jackie's template. :)
