Greetings from Bristol in the west of England.

I’m a veteran producer of in-person meetings for illumination and collaboration.

Three meeting formats, each answering a specific participant requirement:

Spotlight “I want to reach an informed opinion about this issue.”

Prism “I want to understand the particulars of this issue.”

Foglamp “We must establish our shared intent and see a clear way forward.”

Three meeting formats that observe the Max4 Principle

Each format observes the Max4 Principle:

The maximum group size for a proper conversation is four.

Spotlight can accommodate up to 48 participants. With Prism and Foglamp, the upper limit is constrained only by the capacity of the chosen venue.

Spotlight and Prism have fixed formats that are easily mastered. Foglamp extends Prism with activities that are custom-designed to establish common intent and initiate sustained collaborative action.

The new website section I’m creating will showcase each of the three formats.

If all goes well it will be completed before the end of the month.

The 60 pages of the old website are still available, providing a context for the three offerings.

Take a look.

Thanks for stopping by.
