Ecossistemas Humanos nas Organizações
Human Ecosystems in Organisations — the invisible gears of behaviour, climate and leadership · Carlos Wanderley · 2026 · ISBN 978-65-02-20491-7
The book that gave rise to the EHO Method. Through the story of the ship Atlântico VII — a human ecosystem in miniature — it makes visible the phenomena that precede conflict, illness and liability: how decisions, structures and leadership styles shape people's behaviour and, in time, the culture of the organisation itself.
Essential Library of the EHO Method
Some of the works that helped build the EHO Method's view of human behaviour, leadership, organisational culture and psychosocial risks.

Endurance · Alfred Lansing
Pillar 1 — Leadership, purpose and resilience. Ernest Shackleton's journey shows how human decisions, trust and shared purpose hold a group together in the most extreme circumstances. Why EHO recommends it: because real leadership shows up when the supplies run out.

Man's Search for Meaning · Viktor E. Frankl
Pillar 1 — Leadership, purpose and resilience. Written out of the author's experience in the concentration camps, it shows that human beings endure enormous hardship when they find purpose. Why EHO recommends it: because organisations, too, must offer meaning and not merely tasks.

Travail: usure mentale · Christophe Dejours

The Fearless Organization · Amy C. Edmondson
