Our History

Founded by clinical psychologist Dr. J. Clayton Lafferty in 1971 and directed by CEO and organisational culture expert Dr. Robert A. Cooke, Human Synergistics International (HSI) is a pioneer in the field of measurement for organisational and individual development. Dr. Lafferty’s original breakthrough “Circumplex” model, a circular graph for organising and profiling twelve thinking styles, fueled the development and long-term success of one of the first 360º feedback tools, the Life Styles Inventory™ (LSI).

Our History

Forty years later, the LSI continues to be highly regarded and used throughout the world by managers, professionals, and individual contributors to promote self-awareness and develop Constructive personal styles. Concurrently, the LSI has been praised on numerous websites, including LinkedIn; referenced in books and journal articles in business, psychology, and talent management; and cited in newspapers and magazines, including The Wall Street Journal.

After refining and validating the LSI Circumplex, Dr. Cooke became one of the first organisational theorists to propose that people exhibit particular thinking and behavioural styles, either functional or dysfunctional, due to something “bigger” than their personalities or even what is rewarded by their organisations.

That something “bigger” led to the creation of what is now the world’s most widely-used and researched culture survey - the Organisational Culture Inventory (OCI). The availability of this scientifically valid yet practical tool for measuring culture has contributed to a multitude of academic and business publications showing the importance of Constructive Cultures to enhancing the engagement of members, the effectiveness of work groups, and the sustainability of organisations.

Over the past 40 years, HSI has extended its reach and impact by launching international affiliates and offices across the globe and increasing its offerings to meet client needs. HSI retains its research orientation and maintains a strong focus on offering the highest-quality business solutions including world-class diagnostic inventories, team-building simulations, workshops for consultants and coaches, and optional consulting services to support the implementation of its systems and materials.

HSI’s goal is to support consultants, both internal and independent, as well as educators and trainers, in promoting Constructive change and development in individuals, groups, their organisations and, ultimately, the world. We invite you to review our offerings, contact us by phone or e-mail, attend our workshops, and join us in our fifth decade of Changing the World - One Organisation at a Time.
