Can the platform help with content approval processes?
Quick answer
Approval is a workflow function rather than a discovery one, which makes it depend on the tool. Systems built to manage campaigns keep drafts, comments and sign-off in one place, while a pure discovery index does not. It is worth being clear which type you are using, because expecting approval features from a search tool leads to gaps.
Whether a discovery platform handles content approval or whether that belongs to a separate workflow tool.
