ONE SHARED CHALLENGE · NINE DIFFERENT QUESTIONS
One refuge.
Nine ways to reason.
A small mountain refuge makes a rich planning problem. Change a condition, see what follows, and discover what each approach brings into view.
Working, bounded models of a fictional project. Different assumptions are stated in each example.
Change the shared brief
Baseline: air window available, permit evidence assumed supplied, one lifting resource.
The fixed brief and model assumptions
A fictional 7 m² reversible, lichen-grey refuge, rated for 160 km/h wind and −15 °C, with a £465k envelope and a ten-month target. These are scenario requirements, not assessed engineering specifications. Two modules, temporary rig, access windows, action durations, costs and probabilities are explicit toy additions.
Each approach includes only the features needed for its question. Logical steps, abstract time units and calendar windows are not interchangeable; none is a verified ten-month delivery forecast. Permit evidence here is a supplied assumption. Budget is calculated in the sharing/co-design examples; physical load, weather and structural safety are not certified by any tab.
THE VIEWS, SIDE BY SIDE
What changes when the window disappears?
These are different questions about one challenge. The matrix compares the current shared settings with an otherwise identical brief without an air window.
Go deeper into the experiments
The comparison is a small introduction. The fuller investigations keep their own models, sources and questions.
