Organisational Effectiveness Indicator (OEI) framework

Our Organisational Effectiveness Indicator (OEI) framework provides a broad evidence base for us to assure our board, government and the public of the efficiency and effectiveness of our regulation and progress against our Strategy 2020-25, and is based on the Organisation for Economic Co-operation and Development (OECD)’s Nuclear Energy Agency (NEA) Ten Characteristics of an Effective Nuclear Regulator.

The ten OEIs are underpinned by sub-indicators, each with outputs and outcome-based measures, and other key performance indicators to tell us how well we are performing across our operations. When aggregated, these show our progress against our annual plans and strategy.
