Organisational Effectiveness
Organisational culture change consultancy that diagnoses first.
Culture does not change because leadership announces it should. It changes when the conditions that produce it change.
Culture change consultancy delivered by chartered occupational psychologists who diagnose before they intervene, working with senior leadership teams and boards.
Most culture programmes begin with a statement of values and end with a set of expected behaviours. What sits between those two: structural, psychological, and leadership conditions that determine how people behave at work is where most culture change efforts collapse. Wharton Global starts there.

01
The problem
Culture is not moved by communication, training, or a refresh of the values on the wall. It moves when the systems, incentives, and leadership behaviours that produce the current culture are identified and deliberately changed. Organisations that commission culture change without an accurate prior diagnostic are designing solutions to a problem they have not yet correctly defined. The result is expensive, visible, and largely ineffective.
02
What Wharton Global does differently
Our culture work starts with a rigorous diagnostic. Using validated survey instruments, qualitative research, psychological safety audits, and direct observation, we build an accurate picture of the culture as it is experienced across the organisation. That diagnostic identifies what is driving the current culture: the incentive structures, leadership behaviours, informal norms, and process design that produce it day to day.
What makes this different from a standard engagement survey are our Chartered occupational psychologists interpreting the data, conduct the qualitative interviews, and observe the group dynamics that survey data alone cannot surface. The result is a diagnostic that identifies root causes rather than symptoms and interventions that address them rather than describe them.
Interventions are specific to the diagnosis and tied to measurable outcomes. We do not arrive with a standard culture change architecture and adapt it to fit. We build something specific to your diagnosis, your structure, your leadership capability, and what is realistically achievable within a defined timeframe.

Our approach
01
Diagnostic
Validated survey instruments, qualitative focus groups, psychological safety assessment, leadership interviews, and observation.
02
Culture mapping
We map the current culture accurately - what is producing it, who is most influential in maintaining it, and where the pressure points are.
03
Intervention design
A specific programme built around the diagnostic findings, not a generic culture change framework. Interventions target systems, leadership behaviour, and informal norms simultaneously.
04
Leadership development
Where leadership behaviour is a primary driver of the current culture (it usually is), we work directly with the leadership team alongside the wider programme.
05
Progress measurement
Tracked against the validated survey baseline at regular intervals. The organisation always has an honest account of what is shifting and what is not.
04
What it produces
Measurable improvement in engagement, retention, performance, and the quality of decision-making at every level. Culture change work at Wharton Global is benchmarked against validated survey data at the outset and measured at regular intervals throughout. Engagements typically run over twelve months. Organisations consistently report improvements in psychological safety scores, leadership trust ratings, and employee retention.
A US owned global manufacturer with over 50 sites worldwide had a UK plant consistently underperforming against group targets, with a new plant manager who had inherited a team carrying unresolved tensions and operating without shared purpose or psychological safety. Wharton Global conducted a diagnostic across global operations, comparing the site with higher performing plants in the same network and conducting individual and team behavioural assessments. They identified two specific deficits: insufficient personal drive and significantly low psychological safety, the degree to which team members felt able to surface problems and challenge decisions without personal cost. A twelve-month programme of structured team development workshops and individually matched one-to-one coaching addressed both. Performance improved by 20% across core metrics including productivity, on time delivery, and profitability. The workshop programme has since continued annually and is designed to prevent the cultural drift that consistently follows single intervention approaches.
The Wharton way
The standard approach
No psychological expertise, behavioural root causes left unexamined
Consultant arrives, runs a survey, produces a slide deck
Generic frameworks applied regardless of sector, size, or context
Recommendations written for the boardroom, unworkable at team level
Culture treated as a communications exercise, not a behavioural one
External consultant disappears at implementation
Time-bound engagement ends before results are secured
Consultant avoids challenging leadership or addressing uncomfortable truths
The Wharton way
Led through the expertise of chartered psychologists with direct senior leader and board level experience, who understand the decisions you are making, not just the theory behind them
Diagnostic approach that goes beyond surveys to understand context, behaviour, and organisational dynamics
Frameworks shaped around your organisation, not applied regardless of context
A micro and macro approach that works at the level of the organisation and the individual simultaneously
A focus on culture change through sustained behavioural change
Active support through implementation, not just diagnosis
Unlimited and unconditional support, with work defined by outcomes achieved rather than being time-bound
A challenging yet supportive approach that is honest about what needs to change and stands with you through it
06
Who this is for
Organisations where there is a clear and material gap between the culture leadership intends and the culture employees experience.
Those managing the cultural dimension of a merger, acquisition, or significant restructuring.
Organisations where culture has become a driver of underperformance, attrition, or reputational risk and where there is now sufficient leadership will to address it.

Questions we get asked
08
Investment case
A supportive, high-trust workplace culture is associated with a 41% reduction in absenteeism and significantly higher voluntary retention. Organisations that address culture at the structural level consistently outperform those that manage it through communication alone. The cost of replacing an employee who leaves because of culture runs to between one and three times their annual salary before accounting for the signal that departure sends to the people who remain. Wharton Global's culture change engagements are designed to produce measurable improvement in the data that drives those costs, not just the scores that appear in an annual engagement summary.
