Questionnaire overlap is the situation where multiple organizations ask for the same or very similar information through separate forms. In digital government, this creates duplicate data collection, inconsistent records, and unnecessary manual work. The problem is not only administrative: every extra form is another place where sensitive information can be copied, stored, and protected poorly.
From a cyber security perspective, overlap increases risk because the same data may move through different portals, teams, and approval chains. That can lead to retyping errors, weak access control, and confusion about which system holds the authoritative version. Attackers also benefit from duplicated processes, since they can use repeated requests to phish users, harvest data, or exploit inconsistencies between forms. Defenders reduce the risk by reusing trusted data, linking systems through interoperability, and enforcing clear ownership so each field is collected once and protected consistently.
