The Aperture engagement runs in three forms, depending on what the situation requires.

A single conversation. 90 minutes. Enough time for something real to surface and shift. Suitable for a leadership team wanting to test whether this way of working is useful, or an individual facing a specific decision within an organisational context. This is also the natural starting point — if there is not a genuine fit, it becomes apparent quickly.

A half-day or full-day session. For leadership teams with a specific impasse, or for deeper work where a single conversation would only scratch the surface. The longer format allows for more sustained listening and a more thorough examination of what the frame is hiding.

An ongoing relationship. For leaders who want someone they can think with honestly, on a continuing basis. This is the form closest to how the work naturally operates — the diagnostic capacity compounds over time as the relationship deepens and more of the system becomes legible.

A small number of clients at any one time is not a constraint. It is the condition that makes the work possible. The diagnostic capacity this work depends on does not delegate. It requires direct contact with the situation and the people in it.
