A CSM form is a graphical representation of a CSM Business Object that is used to view and input data directly into the Business Object's fields using configurable form controls (text boxes, combo boxes, links, buttons, and so on) and an optional form arrangement (a special tabbed area that displays related data).

For example, when you view an Incident record in CSM, you are viewing the Incident Business Object form; each form control represents an Incident field.
