Industrial diversification, localization and sustainability have become central themes of Saudi Vision 2030 and industrial transformation initiatives. Within this setting, smart manufacturing is not just an issue of technological enhancement but a business model for running plants in which machines, people, materials and decision making connect with trustworthy data. This review explores how IIoT architectural design contributes to productivity, quality and sustainability of Saudi plants. Instead of traditional reviews of technology in which sensors, edge computing, cloud platform, artificial intelligence and digital twin are considered separately, this review treats all of these as components of one path from data signals to factory performance. The structured narrative review technique was used for literature and policy analysis between 2020 and 2025. The findings show that productivity comes from real-time data visualization, overall equipment effectiveness tracking, identification of bottlenecks, scheduling adaptation and predictive maintenance. Quality gains come from traceability, machine vision, statistical process control, process capability analysis and fast root-cause analysis. Sustainability is realized by means of operational measurement of energy, water, waste and carbon footprint indicators and their linking to processes of continuous improvement. At the same time, a set of barriers is found such as legacy equipment, cybersecurity risks, weak data governance, fragmented vendors, workforce skill gaps and different levels of digital maturity of small and medium-sized factories. Finally, this paper suggests phased roadmap for implementation of IIoT architecture in Saudi Arabia starting with readiness assessment and pilot projects. The key value of this paper is in the developed review framework for linking IIoT architecture with productivity, quality and sustainability of Saudi Arabia plants.
