THAC – The Human Aspect

Empower people. Strengthen systems. Build trust.

THAC develops thinking, tools and training on how people and institutions hold together under pressure. Grounded in decades of work in fragile contexts and trauma care, we also offer advice and accompaniment to organisations and processes.

Two tools to start with

  • Trajectory Scan → Does your strategy, project or organisation strengthen development – or reinforce erosion? For whom? Puts the Relational Systems Framework to work. Pilot, free to use – feedback welcome.
  • Trauma-Informed Organisation – Self-Assessment → For organisations that want to become trauma-informed: check where you stand, see where action is needed and get recommendations grounded in research, guidelines and law. A separate tool from THAC’s trauma work. Pilot, free to use – feedback welcome.
