The Executive FiRE Index, or EFI for short, is based on the FiRE model of resilience. The abbreviation FiRE stands for “Factors improving Resilience Effectiveness®.”The central message is that resilience is not just an innate trait. It is also a skill that can be learned and internalized. Scientifically based strategies, which are bundled in the individual spheres of the FiRE model, help to achieve this.The Executive FiRE Index is conducted at least twice to document the development of inner fire.Those who work on their resilience typically see progress over time in resilient micro-strategies, habits, and life satisfaction, or state. In contrast, innate personality traits remain largely unchanged.The first EFI measurement is taken at the beginning of a coaching session or resilience development program. The second measurement is taken after 6 months.Each measurement uses a structured questionnaire with around 100 items to record all factors that influence inner fire.The results are summarized in an easy-to-understand 28-page report, which also contains specific recommendations for daily practice.This report is then discussed step by step with a Certified EFI Practitioner.
