Which of the following is the GREATEST impact to an enterprise that has ineffective information architecture?

Poor desktop service delivery is typically an operational IT issue, distinct from the overarching structure and usability of an enterprise's information.

Data retention is a governance aspect, a symptom or component within information architecture, but not its greatest overall negative impact.

Redundant systems are a symptom of poor application or technology architecture, which can contribute to information issues, but the ultimate detrimental effect on the business is the inability to make sound decisions.

Ineffective information architecture results in disorganized, inconsistent, or inaccessible data, making it exceedingly difficult for decision-makers to obtain accurate and timely insights.
