I'm still learning SharePoint and I'm coming getting stuck on whether to create a new content type or add a site column to an existing content type.
For example, I created a base company document content type that has a few columns that every document the company uses will have. I plan on creating content types for every form they use. Some of the forms have a reference to the process that the form belongs to. Would it be better to create another content type called reference that would link to the forms or add a column to the base company document content type that would describe the type (form, reference, etc...)?
