@Charles.Ball @Anonymous let me explain this workflow (apologies for the long explanation).
To understand this workflow, imagine a multi-disciplinary environment where you are the Architect working in the Architecture team folder. You also have the Structure Consultant working in the Structure team folder, Mechanical consultant working in the Mechanical team folder, and so on.
In this case, you will not have access to the Structure or Mechanical team folder to link their live Work in Progress (WIP) models, unless you are a Project Admin. And even then, you would not want to live link their models (trust issue).
Let us now look at the working of BIM 360 Design in this case to understand various versions.
Scenario 1: Your own team members (Revit users who have live access to the Work In Progress (WIP) models in your team's folder). Every time you make changes to your design and sync, your team members can sync or reload the latest to see the changes. This is also termed as a "High Trust Environment" where you trust everyone in the team, hence they get live access to your WIP models. In this case, PUBLISHING IS NOT REQUIRED as you are live linking the WIP models from your own team folders.
Example: In your Architecture Team, you have 10 Revit users working on a couple of Revit models (linked) from the Architecture Team folder (Facade and Base Building). They have live access to the models and can sync or reload to see the changes. So if these 10 users sync their models 10 times a day, you will have 100 Sync versions per day (shown in the 1st column of the image added by @ThierryMonteyneSWECO ). These models ARE NOT available on the Document Management interface as Syncing will not make these models available on BIM 360 Docs.
Now, what if you have Non-Revit members in your Architecture team, such as Project Architects? They still want to have a look at the model every now and then. In that case, you will Publish the model (manually or scheduled publishing). Publishing is a process of making your Revit models (with the selected views and sheets in the Publish Set) available on the Document Management interface for your Non-Revit team members to view in a Web Browser or a tablet device. NOTE THAT in the Web browser or tablet, they can only see the views or sheets you included in your Publish Set in Revit. The Published versions are shown in the 2nd column of the image added by @ThierryMonteyneSWECO. Hence the number of versions in the 2nd column are less than the first column (twice a week compared to 100 times a day).
Scenario 2: The Revit users of external teams (Structure, Mechanical, Electrical, and so on). These users work in their own Team Folders and you do not have access to their models (like you don't have access to theirs). Now, as per your BIM Execution Plan, you decide to share your models with other teams once a week. In that case, you will have to Publish the latest models. Once the models are Published, you can share them as packages with other teams using the Design Collaboration service.
Example: Structure Team Publishes its model twice a week (for their Non-Revit users). However, they are only required to Share their package with you Once a week, as per the BEP. This is shown in the 3rd Column of the image by @ThierryMonteyneSWECO . Hence the number of Shared versions are less than the Published versions.
Once that happens, you get a notification (optional) that the Structure Team has Shared a package. You can then compare their current shared version with the previous one. If the changes they made are going to cause issues in your model, you can inform them about that and decide NOT TO CONSUME their package. In that case, the Structure consultant makes the changes and then publishes and shares the package again. You then Consume their updated package that is copied into your Team's consumed folders (Architecture > Consumed > Structure). This is shown in the 4th column of the image by @ThierryMonteyneSWECO.
Because you can decide not to Consume all the Shared Packages, hence the number of Consumed versions are less than the Shared versions.
Hope this makes sense.
