use of communications and information systems that are familiar to users is a part of which key principle?

Use of communications and information systems that are familiar to users is part of the Reliability, Scalability, and Portability key principle in NIMS communications and information management.

Quick answer

  • The specific key principle this phrase refers to is Reliability, Scalability, and Portability.
  • In FEMA/NIMS doctrine, “familiar to users” appears directly under the definition of reliable systems: communications and information systems should be reliable – familiar to users, adaptable to new technology, and dependable in any situation.

Why this is the correct principle

  • FEMA’s IS-700 NIMS training materials list four communications and information systems principles:
    • Interoperability
    • Reliability, Scalability, and Portability
    • Resilience and Redundancy
    • Security
  • Under the slide for Reliability, Portability and Scalability , FEMA explicitly states that systems should be reliable – familiar to users, adaptable to new technology, and dependable in any situation.
  • Some Q&A sites repeat this exact question and confirm the answer as Reliability, Scalability, and Portability , matching the FEMA wording.

Related context (helpful for tests)

  • Reliability : Systems are dependable, available when needed, and familiar enough that users can operate them under stress without extra training.
  • Scalability : Systems can handle a growing number of users and higher traffic as an incident expands.
  • Portability : Systems can be moved, deployed, and integrated across jurisdictions and agencies.

So, if you see the line “use of communications and information systems that are familiar to users is a part of which key principle?” on an exam, the correct choice is: Reliability, Scalability, and Portability.
