Hey Omid, I’ve recently been working through this challenge as well. Our company adopted Shape Up in September/October.
There are a few people on our team who expressed interest in shaping and pitching and asked for help getting started. There were also some folks (mostly designers) who felt like the projects they were being assigned were too prescriptive.
In order to help both types of people contribute at a more strategic level, I created a pitch template that has been working pretty well for us. You’re more than welcome to copy it and make it your own.
I’m also happy to chat through any of the details here.
