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

Jude's plan is a performance budget. A performance budget sets quantifiable limits on various performance metrics (like load time, page weight, or number of requests) that a website or application must adhere to. This ensures that performance remains a priority throughout development and deployment. In this case, Jude established a minimum acceptable level for site speed metrics, directly aligning with the definition of a performance budget. A latency limit is too narrow; while latency is a component of speed, a performance budget encompasses broader metrics. "A performance plan" and "a speed plan" are generic terms that lack the specific, quantifiable nature implied by setting limits that cannot be fallen below.
