Human Synergistics Diagnostic
Understand the
causes of your culture
The Organisational Effectiveness Inventory (OEI) is the partner diagnostic to the OCI. Where the OCI measures what your culture is, the OEI measures the levers that create it — and the outcomes it produces.
The diagnostic that explains the “why”
From Human Synergistics, the OEI surveys members on the things that influence culture and the results that flow from it. It connects the causes of culture to its measurable effects, so you know not only what your culture is, but why it is that way — and where to focus change.
Causal factors
The levers that shape culture
The OEI measures five causal factors — the levers that, together, create the behaviours members believe are expected of them.
Mission & philosophy
The articulated purpose, values, and guiding beliefs that signal to members what the organisation stands for.
Structures
How roles, reporting lines, and decision rights are arranged, and how much influence members feel they have.
Systems
The processes for appraisal, reward, selection, and goal-setting that quietly shape day-to-day behaviour.
Technology
The tools, workflows, and job design that determine how work actually gets done across the organisation.
Skills & qualities
The capabilities and interpersonal qualities of leaders and members that bring the culture to life.
Outcomes
The results culture produces
Alongside the causal factors, the OEI captures the outcomes of culture at three levels — so you can see how the levers translate into real effects.
Individual outcomes
Role clarity, motivation, satisfaction, and intent to stay — how culture is experienced by each person.
Group outcomes
Teamwork, co-ordination, and the quality of relationships between the groups that have to work together.
Organisational outcomes
Adaptability, quality of service, and overall effectiveness at the level of the whole organisation.
Better together
Designed to run alongside the OCI
The OEI is typically run together with the Organisational Culture Inventory (OCI). Read side by side, the two diagnostics connect the causes of culture to its effects: the OCI shows what the culture is, and the OEI explains why — and what to change.
- A comprehensive measure of the causal factors that drive and shape culture
- Outcomes captured at three levels — individual, group, and organisational
- Designed to be paired with the OCI for a complete picture of culture
- Benchmarked against a large international research database
What your culture is
The behaviours members believe are expected of them, mapped on the Circumplex.
Why it is that way
The causal factors that shape culture and the outcomes it produces.
What you get
By measuring both the causes and the effects of culture, the OEI turns culture change from guesswork into a targeted, evidence-based programme.
Understand the why, not just the what
See why your culture looks the way it does, so change targets root causes rather than symptoms.
Find the levers to pull
Identify the specific structures, systems, and skills to adjust to shift behaviour and culture.
Connect culture to results
Link the behaviours expected of members to engagement, quality, and performance outcomes.
Track the impact over time
Re-measure to see how interventions move both the causal factors and the outcomes they produce.
