Earned value management (EVM) is a project management technique that integrates scope, schedule, and cost to measure project performance and progress. The CGEIT Review Manual 8th Edition highlights that EVM’s greatest advantage is its ability to provide a clear, quantifiable measure of project progress that stakeholders can easily understand.

Extract from CGEIT Review Manual 8th Edition (Domain 5: Benefits Realization):"Earned value management provides a standardized, easy-to-understand measure of project progress by comparing planned value, earned value, and actual costs. This enables stakeholders to assess whether a project, such as a blockchain implementation, is on track to deliver expected benefits." (Approximate reference: Domain 5, Section on Project Performance Measurement)

Providing a measure of project progress that is easy to understand (option B) is the greatest advantage, as EVM offers clear metrics (e.g., cost variance, schedule variance) that help executives and stakeholders gauge the success of blockchain projects for IT contracts management.

Why not the other options?

A. It automates project progress reporting to business executives: EVM is not an automated reporting tool; it requires data collection and analysis.

C. It eliminates potential risks related to project earnings: EVM identifies variances but does not eliminate risks.

D. It enables accurate forecasts of the number of blocks to be completed: EVM measures progress in terms of value, not specific technical outputs like blockchain blocks.
