Life Styles Inventory™

Great leaders aren’t born, they’re developed. The Life Styles Inventory® (LSI) is a powerful, research-backed tool that helps individuals and leaders build self-awareness, shift unproductive behaviors, and lead more effectively.

Reveals how leaders think, behave, and lead under pressure.

The Life Styles Inventory™ (LSI) is an organisational tool that uses both self-assessment and colleague feedback to identify individual thinking and behavioural styles. By providing insights into strengths and areas for development, it empowers people to embark on their own journeys to being better at, and enjoying more, everything they do.

“Research and development by Robert A. Cooke, Ph.D. and J. Clayton Lafferty, Ph.D.. Designed for managers, leaders, students and those in professional and technical roles, the LSI has helped millions of people to understand and change the way they think and behave.”

What is the LSI?

The Life Styles Inventory® (LSI) is our most widely used individual development tool for leaders and professionals. It combines self-assessment and 360° feedback to reveal how your thinking and behaviour impact your effectiveness both as you see yourself, and as others experience you. Backed by decades of research and used by thousands of organisations, the LSI is academically rigorous and proven in the real world to help leaders grow, improve performance, and achieve better results.

The LSI brings together two perspectives. LSI 1 captures how an individual sees their own thinking styles, effectiveness, and satisfaction at work and home. LSI 2 gathers feedback from peers, managers, and or direct reports, revealing confirmed strengths, blind spots, and gaps between intention and impact. Results are delivered in a confidential report and explored with a Human Synergistics consultant or accredited practitioner. This guided conversation turns insight into practical strategies for changing thinking and behaviour. The surveys are available online across most devices, with hard copy options also available.

Why Use the Life Styles Inventory™ (LSI)
Build Self-Awareness

Understand how your thinking and behaviour influences leadership effectiveness, performance, and relationships. Awareness is the first step toward growth.

Strengthen Relationships

Improve communication, collaboration, and team dynamics by understanding how your behaviour is perceived by others.

Improve Performance

Data driven insights provide clear, actionable feedback on how your mindset affects decision-making, teamwork, and leadership effectiveness.

A Path to Growth – Not a Fixed Label

Unlike personality or preference based tools, LSI isn’t about fixed traits – it’s an invitation to learn, grow, and develop.

Develop Resilience & Adaptability

Learn to shift unproductive thinking patterns, handle challenges more effectively, and build a leadership approach that fosters long-term success.

Track Improvements Over Time

Leadership development isn’t a one-time event – it’s an ongoing journey. Remeasure every 12-24 months to track progress and reinforce positive changes.
