Option A is the best answer because CHFI v11 explicitly states that organizations should monitor and maintain accurate metrics and detailed tracking information related to eDiscovery . The question also emphasizes progress monitoring , data integrity and accuracy , and cost control , all of which are best supported by clearly defined metrics and stage-by-stage measurement.
By defining KPIs and measuring the volume of information at each stage , the company can track bottlenecks, evaluate collection and processing scope, manage costs, and ensure that the eDiscovery lifecycle remains defensible and organized. This is directly aligned with the CHFI blueprint's eDiscovery objectives, which treat measurement and tracking as core best practices rather than optional administrative tasks.
The other options can still add value, but they do not address the question as directly. A centralized repository, cross-functional oversight, and training all help operations, yet the CHFI-aligned priority for monitoring effectiveness and controlling cost is accurate metrics and detailed tracking information .
Therefore, the strongest answer is to define KPIs and measure information volume throughout the eDiscovery process.
