Whether you use todo.space or not, whether you manage your project in a spreadsheet (sorry, I meant to say "Monday" but then remembered it doesn't have formulas /s), you should never skip project decomposition.
Not only it will help you divide and conquer your deliverables and keep everyone accountable, but it also creates clarity and a great sense of accomplishment when things get done.
Take a look at the video below, how to use project decomposition to divide and conquer a huge project, and how to extract completed deliverables into completed projects to declutter your workspace and get a sense of accomplishment.
It's easier in todo.space than in Excel (even though, Excel has formulas and pivot tables).
