Certified Experts

Accredited in a range of internationally recognised leadership and team management tools

TMS Suite of Products

Team Management Systems – particularly the Team Management Index Profile (TMP/TMI) – is recognised as the foremost integrated system of work-based, research-proven assessments and feedback instruments worldwide. These support individuals, teams and organisations to effect positive and lasting change and achieve higher performance in the workplace.

The Lominger Leadership Architect SuiteⓇ of Products

The suite represents a collaboration of research-based findings and practical, user-friendly tools, applications and development solutions. It enables organisations to bridge the gap between the way most executive development systems are actually run, to the way research-based best practices in management indicate they should be run.

DiSCⓇ Profiling

DiSCⓇ is a leading personal assessment tool that reports on the personality and behaviour of individuals. It’s non-judgmental and helps people to discuss their behavioural differences, resulting in improvements in work productivity, teamwork and communication.

Myers Briggs Type IndicatorⓇ

The MBTIⓇ is a practical tool for investigating personality type, and provides a dynamic framework for understanding individual differences and preferences. It helps clients to better comprehend the culture of their workplaces, develop new skills, understand their participation in teams, and cope with change at work.

360° Feedback Assessment & Values Style Profile

360 degree feedback involves a team member receiving anonymous, confidential feedback from the people who work around them, including their manager, peers, and direct reports. The Values Style Profile helps someone understand what internally motivates them and guides them in their decision making.

Appreciative Inquiry

An approach to resolving workplace conflict developed in the 1980s by a team at Cape Western Reserve University in Ohio, US. It enables resolution by focusing energy on what is working rather than what isn’t.

Hogan Assessments

These tools acknowledge that people don’t always fit in a box. Hogan’s four assessments offer the range of measurement required to understand people’s strengths, weaknesses, values, and their approach to problem solving – and accurately predict performance.

Gallup StrengthsFinder

The StrengthsFinder differentiates strengths from talents and preferences. It identifies the skills and attributes that someone uses, and provides information on how these can be leveraged effectively at a personal and organisational level.
