The biggest danger to facilities management data is:

• A. Data redundancy
• B. Rapid retrieval
• C. Over-organization
• D. Obsolescence

Answer: (D)

In facilities management, data must stay usable for the entire life of the building and its systems. When information becomes obsolete, records may no longer reflect the actual assets, configurations, or practices, making them unreliable for planning, maintenance, and compliance. Obsolete data can mean unreadable file formats, retired software, missed updates to equipment specs, or expired warranties, all of which lead to incorrect work orders, safety risks, increased downtime, and higher costs because decisions are based on out-of-date facts.

Data redundancy is a risk because duplicates can cause inconsistencies and waste, but it doesn’t inherently prevent operations like obsolete data does. Rapid retrieval is a benefit, not a danger, and over-organization, while potentially cumbersome, isn’t the primary threat to FM data integrity.
