This document presents an overarching structure for a consulting project proposal deck. It includes the high-level presentation flow, as well as specific slide structure and verbiage structure. You can follow it as a general presentation template. Details are more geared towards strategy projects, but the core concepts can be applied to any project.
This structure and template can be used for pitch decks, project kick-off presentations, as well as for specific status meetings after the project is underway.
