The Differentiated Influence of Digitalization of United Kingdom Manufacturing Industry on Operational Performance-A Comparative Study of Large Enterprises and Small and Medium-sized Enterprises as an Example

Abstract

Amid labour shortages, high energy costs and supply chain volatility, UK manufacturing is leveraging digitalisation to enhance operational performance and resilience. At the enterprise level, digital intensity correlates positively with productivity, with large enterprises leading Small and Medium-sized Enterprises (SMEs) in digital capital, data governance and system integration. The national ‘Made Smarter’ programme lowers barriers through diagnostics, funding and training, bolstering organisational capabilities. This paper compares multiple indicators to examine digital pathways and returns. Large enterprises prioritise master data governance and system interface cleansing, following a ‘governance-first, compounding gains’ trajectory. BAE Systems' ‘Future Factory’ and Rolls-Royce's digital twin initiatives demonstrate sustained improvements in lead times and Overall Equipment Effectiveness (OEE). SMEs follow a ‘bottleneck prioritisation – visualisation – small-scale automation’ approach, achieving localised improvements in First Pass Yield (FPY) and lead time reduction within 3-6 months. However, without comprehensive process and data governance, returns plateau during expansion phases. Predictive maintenance research underpins reduced downtime and stable delivery. This paper establishes linkages between metrics, mechanisms, and case studies, proposing reusable implementation sequences and key human-factor governance principles.
