Every Result Starts With a Decision

Revenue. Safety. Leadership. Retention. Culture.

Every organisational outcome begins with thousands of decisions made every day.

Yet while organisations measure the outcomes, few measure the quality of the judgement behind them.

This short introduction explains how Judgment Index™ provides a scientifically validated way to understand how people make decisions, helping organisations identify strengths, uncover hidden risks, and improve performance from the inside out.

Discover why judgement may be the missing measure behind your most important business results.

Discover What’s Inside Our Reports

The insight that used to require a retained organisational psychologist and a six-figure consulting engagement is now available to any Australian organisation in twenty minutes.

Most organisations have not had access to this kind of data before.

Now they can.

The Judgment Index™ measures how individuals operate across personal and professional environments helping organisations better understand leadership, decision-making, wellbeing, and performance.

Using the “Cake Theory,” the model illustrates how strong judgement is built on a foundation of self, supported through work performance, and strengthened through balance and awareness.

By understanding these interconnected layers, organisations can better support their people, improve outcomes, and build healthier workplace cultures.

    “Using the Judgment Index assessment in our company has given me more confidence in the hiring decisions of our managers across the country and has helped with development of our staff. We have noticed a 10% increase in staff retention and 80% reduction in workers compensation claims as a result of better hiring choices and people management since we started using the JI.”

    “Most human resource, assessment tools are at least a generation behind the current dynamics prevailing in modern organisations. What you have in the Hartman Value Profile (known as the Judgment Index™) is the next generation human resource tool.”

    “As Director of Business and Corporate Services, in 2025, we sought an evidence‑based, values‑driven assessment tool that could offer participants meaningful insights into their leadership maturity and judgement, including their engagement drivers and opportunities for development. The Judgment Index™ delivered exactly that.

    What sets the Judgment Index™ apart is its focus on the underlying value system that drives decision‑making-an important point of difference from traditional personality assessments.

    The ability for leaders to exercise sound and skilful judgment is essential in building a resilient, proactive organisation built on creating shared value.

    The Judgment Index™ provided the depth of insight needed to support that aim.”
