Gerald is the product manager for LaughItUp.com, a website for comedians. Earlier this year, many comments from site feedback complained about poor responsiveness. Working with the site marketing and development teams, Gerald created a plan where the site responsiveness metrics couldn't fall below a certain level. Which plan type is Gerald's plan?

A performance budget is correct because it sets specific limits on key site performance metrics, such as responsiveness, to ensure the website maintains a consistent and acceptable user experience. By implementing a performance budget, Gerald and the LaughItUp.com team can monitor and enforce these standards, preventing degradation in speed and responsiveness that could negatively impact user satisfaction and conversions.
