During an iteration review, some product features face cancellation risk because of high operational costs at production. Which type of analysis should the project lead have performed to prevent this?

Benefits analysis is the correct answer because it evaluates the positive outcomes and value a project or feature is expected to deliver, including considering long-term operational costs. Had a thorough benefits analysis been conducted, the high operational costs would have been identified earlier, allowing for design adjustments or alternative solutions to mitigate the cancellation risk. Risk analysis focuses on identifying and assessing potential threats and opportunities, but a benefits analysis specifically ties the value to the costs. Capacity analysis assesses resource availability, and gap analysis identifies differences between current and desired states, neither of which directly addresses the long-term operational cost implications for feature viability.
