A facilitation deck

Aperture

Images that surface what language can't.

An image is shown.

The participant speaks.

What surfaces is the work.

Aperture is the deck. Participants meet it on their own devices. No session-management chrome. No insights engine. What you see is the image.

The image holds what the group cannot yet name.

It functions as a transitional object, neither self nor other. It absorbs what participants need to put somewhere. The image lets people speak about authority, dependency, grief, or exclusion through the image rather than at each other directly.

Two lineages anchor the work: image-based facilitation and the 4MAT learning cycle. Practitioners design sessions using one, the other, or both.

Built by a practitioner.

Aperture is curated by John Weng, PhD · ICF PCC · group relations practitioner in the Tavistock tradition. The deck grows out of his practice, not adjacent to it. Every image clears a rigorous research validation process before it makes the deck.

Made for any practitioner.

The depth is the source, not the requirement. The same deck holds for a leader running a team offsite as it does for a Tavistock-trained consultant working a group relations event. Accessible and rigorous, by construction.
