How do I know my content is ready?
It might seem like you need a comprehensive and perfect set of content—reviewed, tested, and fully standardized. While that would be ideal, it's rare and doesn't happen overnight.
Instead, focus on having a single source of truth. It's not about the current state of your content, but its ability to grow and evolve with its users, that truly makes it perfect.
If you literally have no content, start with Revit out-of-the-box content (available as a channel in content catalog) and take a small set of items you would like to standardize that is used on most projects. If you have residential work for example, maybe the kitchen items, a set of cabinets, some appliances and countertops. This will be enough to help people see a vision for what it could be like for other tasks they work on.
How do I make my content ready?
As it turns out the content you have is ready no matter the state. It's the process and accessibility you need to build around it that needs to be in place.
Start with what you have and do the following:
Organize - Use Smart Collection Organization to allow for there to be vetted content and a public sandbox for unvetted content. Then you can also make work in progress or development collections that give admin only, a place to prep and vet content.
Collect - Use Content Catalog to manage uploads. Allowing general users to upload content that you can approve to be shared as vetted or unvetted content lets users tell you what is needed and gives them something to work with until you have a vetted solution for them.
Save Searches - When you search in Content catalog and use filters to narrow results to a subset of content that is useful to have together for a given task, save it and share it with your company as a saved search. Smart Saved Search Organization is full of examples to make things easier to find what you need, when you need it, like project kickoff, market sectors, drafting details and more.
