[ WHS Management Plan ]
A WHS Management Plan copied from the last project and lightly edited stops being genuinely site-specific. Novato starts from your account-wide defaults for the parts that don't change project to project, and asks only for what's actually different about this site.

Standard WHS responsibilities and consultation arrangements that apply across your projects, so you're not rewriting them every time.
The health and safety rules that actually apply to this site — leave the rest blank to use your account default.
A particular project can override the responsibilities or consultation arrangements default if it genuinely needs to.
A project-specific WHS Management Plan, built from real defaults plus real site rules, not a copy-paste job.
A WHS Management Plan documents how health and safety is managed on a specific project — Novato's role is making that document genuinely reflect the site (not a copy of the last one) by separating what's genuinely project-specific from what's a standing company default.
No — responsibilities and consultation arrangements default to your account-wide settings unless you override them for a specific project.
Projects that haven't overridden a section will reflect the updated default; projects with their own override keep what was set specifically for them.
It's your record of how WHS is managed on the project — the substance of what you put in it is your responsibility, the same as any WHS Management Plan.
