Organisational Culture & Effectiveness Inventories®

Your organisation’s culture is shaping every decision, every interaction, and every result. The Organisational Culture Inventory® (OCI®) and Organisational Effectiveness Inventory® (OEI®) are the world’s most widely used culture diagnostics.

Culture Diagnostics and Survey Tools That Drive Meaningful Transformation

Your organisation’s culture is shaping every decision, every interaction, and every result. The Organisational Culture Inventory® (OCI®) and Organisational Effectiveness Inventory® (OEI®) are the world’s most widely used culture diagnostics. Together, they give you the clearest picture of your current workplace culture, the causes behind it, and the actions you can take to build the culture you need for success.

“We use the Organisational Culture Inventory (OCI) and Organisational Effectiveness Inventory (OEI) together because they provide a complete picture of how your organisation works. The OCI measures the behaviours that define your culture, while the OEI identifies the systems shaping it. Together, they enable targeted, meaningful change. Developed by Dr Robert A Cooke and Human Synergistics.”

What is theOCI & OEI?

The Organisational Culture Inventory (OCI) and Organisational Effectiveness Inventory (OEI) are research based diagnostics that show how your organisation really works. The OCI measures the behaviours people believe are expected of them to succeed, revealing the norms that shape performance. The OEI looks at the systems, structures, and leadership practices that drive those behaviours. Together, they show not just what your culture is, but why it exists. The model looks at four connected areas. Ideal Culture – our aspiration reflects what we say we stand for. Causal Factors – how we do things around here are the systems and signals that shape behaviour in real time. Actual Culture – the signals people act on captures what people believe is truly expected to succeed. Outcomes – what results from the culture we have shows the impact, where constructive cultures lift motivation, quality, safety, and innovation, while passive or aggressive cultures drive stress, risk aversion, and disengagement.
