The Safety Decision Intelligence Assessment (SDIA™) has been developed by drawing upon decades of international research across leadership, human factors, organisational psychology, decision science, risk management, and safety culture.
Rather than relying on a single model or theory, SDIA™ integrates multiple evidence-informed disciplines into a practical framework designed to support leadership development in safety-critical environments.

Section 01
Every day, leaders make hundreds of decisions that influence safety performance.
Many incidents are not caused by a lack of technical knowledge but by the way decisions are made under uncertainty, pressure, competing priorities, incomplete information, organisational culture, and human behaviour.
SDIA™ focuses on understanding these decision-making tendencies to support better leadership, stronger safety culture, and continuous organisational learning.
The Decision-to-Performance Chain
Each decision a leader makes ripples through behaviour, culture, and ultimately organisational safety performance.

Section 04
A proprietary model developed by Demoura Lawson Consulting, combining multiple evidence-informed disciplines into six practical intelligence dimensions that support reflection, coaching, and leadership development.
The ability to analyse complex information, evaluate evidence, and apply critical thinking under uncertainty.
Consistency, procedural adherence, and structured decision-making in operational environments.
Leading with empathy, trust, and psychological safety to influence team performance.
Flexibility in thinking, adapting to changing conditions, and managing ambiguity effectively.
Assessing risk, weighing trade-offs, and making sound judgements under pressure.
Visible safety commitment, coaching, and fostering a culture of learning and improvement.
Section 05
Six principles that guide every decision in the development and application of SDIA™.
We ground our work in established research, not untested hypotheses.
We focus on development and growth, not blame or criticism.
We believe safety leadership goes beyond rule-following.
SDIA™ is designed to support growth, not just measure it.
Human judgement always precedes automated recommendations.
Processes exist to serve people — not the other way around.
Section 06
SDIA™ is designed as an evolving professional assessment. Demoura Lawson Consulting is committed to continually strengthening the platform.
Research
Ongoing study into leadership and decision science.
Pilot Studies
Real-world testing before wider release.
User Feedback
Practitioner input shapes every iteration.
Psychometric Validation
Continual assessment of reliability and validity.
International Benchmarking
Comparison against cross-sector data.
Professional Collaboration
Working with experts across disciplines.
SDIA™ emphasises continuous improvement rather than claiming completed scientific validation. The framework will continue to evolve through ongoing validation, research, and practical application.

SDIA™ has been developed to bridge the gap between research and practice. By integrating established knowledge from multiple disciplines into a practical leadership development framework, the platform helps individuals and organisations better understand how safety-critical decisions are made, how leadership influences culture, and how continuous learning can strengthen organisational performance.
