This review examines how a national broadband key performance indicator framework can measure the contribution of fibre to the home to Saudi Arabia’s Vision 2030 digital goals. The paper argues that broadband assessment in the Kingdom should move beyond rollout counts and headline speeds toward a layered dashboard linking FTTH to adoption, affordability, quality, inclusion, and public value. Using a structured review of peer reviewed studies and policy reports published between 2020 and 2025, the study synthesizes Saudi official sources, international benchmarking systems, and the empirical literature on high speed broadband effects. The review asks which indicators best capture FTTH progress, how those indicators should be grouped, what kinds of impacts can reasonably be associated with FTTH, and how Saudi institutions should govern a national dashboard. The findings show that a credible framework must combine leading indicators such as homes passed and service availability, intermediate indicators such as subscriptions, affordability, latency, upload performance, and reliability, and lagging indicators such as digital service use, SME digitalization, telehealth uptake, and digital economy value added. The paper concludes by proposing a KPI architecture and governance principles for aligning broadband measurement with Vision 2030 execution.
