What is a disadvantage of a single entry interface?

• A. Immediate response to transactions
• B. Increased accuracy in entry
• C. Response to a transaction is not immediate
• D. Higher training costs

Answer: (C)

A single entry interface typically allows users to input data in a simplified manner, but one of its notable disadvantages is that the response to a transaction is not immediate. This can occur because, in a single entry system, the transaction data may need to be processed or reviewed before it reflects in the system or can be utilized for analysis and reporting. This delayed response can hinder real-time decision-making and operational efficiency, particularly in environments where timely data is crucial for strategic operations.

The other options highlight positive aspects of a single entry interface rather than disadvantages. Immediate transaction responses and increased accuracy in entry are beneficial characteristics, making transaction handling more effective. Additionally, while higher training costs might be an issue in other systems, a single entry interface is often simpler to use, which usually leads to lower training requirements rather than higher ones.
