Items are submitted to collections using workflow steps with forms. Each collection can have its own customised submission steps and forms.
Researchers may complain of a submission process that is onerous and takes too much time. A possible remedy is to create very simple submission forms per faculty/school/department for "quick" submissions. After submission, then let the faculty/subject librarians perform the submission workflow of reviewer, or metadata editor and then move or map the item into the correct collection.
Step 2 - Define submission forms, as per the steps defined above and which may have custom input fields per form
Step 3 - Activate new forms
