What describes the relationship between information quality and decision speed/accuracy?

• A. Timely, accurate, relevant information improves speed and accuracy; poor or excessive information degrades both.
• B. Speed is independent of information quality.
• C. Only accuracy matters, irrespective of speed.
• D. Information quality only affects analysts, not decision makers.

Answer: (A)

Quality of information shapes both how quickly decisions can be made and how reliable those decisions are. When data is timely, accurate, and relevant, the decision-maker can quickly orient to the situation, compare options, and commit to an action with confidence, which speeds the decision cycle and improves the likelihood of a correct outcome. If information is poor, incomplete, or off-target, decisions take longer and are more prone to error because the brain is operating with uncertain or misleading cues.

Overload is another part of the picture. Even if data is fast, if it’s excessive or not properly filtered, it can overwhelm the decision-maker and slow the process or degrade accuracy. So, information quality isn’t just about having data; it’s about having the right data at the right time, in a form that supports timely and correct action. In Marine Corps command and control, this means designing information flows that emphasize validation, relevance, and timeliness, while using filtering and prioritization to prevent overload.

The other ideas don’t fit because speed does not occur in a vacuum from information quality, and accuracy alone doesn’t guarantee good decisions if pace is sacrificed. Information quality also matters for decision-makers, not just analysts, since those quality cues drive the choices and tempo of action.
