Hi Stuart! Thanks for the question:) I cover some parts generally understood under 'scope' in other parts of the template (timings, target audience, key results) so I tend to use that section to describe product areas we already know we need to tackle, e.g. global navigation, information architecture overhaul, visual design update, redesign of a certain category of an app/website, etc.)
The purpose of the template is primarily to have meaningful discussions and to document common ground. It started as a one-pager, currently it's more of a two-pager, but I still try to keep it short and if needed, I link to more detailed descriptions elsewhere.
