A scenario holds a whole piece of analysis: the subset, the parties, the settings it was run on and the results that came out. Save it and anyone on the project can open it and see the same numbers, without re-running anything.

This works the same way in Sloc Local and Sloc Concentrate.

Save it

Until you save it, a scenario is titled Unsaved scenario. Click the save icon at the top right, give it a name and a description, and click Save.

Use the description for what the scenario represents, not what it's called. "All party sites, 1km straight-line, share of sites" tells a colleague - or you, in three weeks - far more than "Scenario 2".

The scenario bar

Once saved, the name sits at the top of the results with its controls around it.

• The pencil renames it and edits the description.

• The folder opens another saved scenario.

• The reset icon clears the pane so you can start a new one. It doesn't delete what you've saved.

• At the right, save stores changes and download exports the results. The save icon greys out when there's nothing new to save.

Open one

The Open scenario window lists the project's saved scenarios, each with its description, when it was last analysed and when it was last changed. The one you're in is marked Active; the others have an Open button. Show scenarios from switches to another data version's scenarios, and the bin deletes one for good.

Expand Scenario settings on any of them to see what it was run on - the subset, the parties and their site counts, the catchment and how shares were measured - without opening it.

Sharing

There's no separate step: a saved scenario belongs to the project, so everyone with access to that project sees it in this list, with its results and the thresholds you set. Who those people are is managed on the project itself - see how to share a project and manage access.

When the results no longer match

Change a setting in the pane after a run - a different target, a wider catchment, another metric - and the results on the right are still the old ones. The Analyse button lights up again to tell you so. Re-run before you read or download anything, then save to keep the new results against the scenario.

Pro tips

• Save before you start varying things. A saved base case plus a saved variant can be compared; an overwritten scenario can't.

• Put the thing that changed in the name - "2km", "targets only", "no divestment" - so the list reads as a set of options rather than a pile of attempts.

• Scenarios belong to the data version they were run on. If one you expect is missing, check Show scenarios from before assuming it's gone.
