Most leadership teams are not short on intelligence. They are short on protected space to think. Executive meetings are consumed by delivery, targets, people issues and whatever caught fire that week. The urgent crowds out the strategic.
Mental Sandboxing is a two-hour strategic rehearsal for leadership teams. No preparation. No generic workshop theatre. No long presentation followed by polite agreement. The session starts with a sharp external briefing built around relevant research, emerging trends, weak signals, business model shifts and uncomfortable scenarios.
The rest is facilitated debate. The aim is to surface the strategic issues your operating rhythm keeps suppressing.
What is your failure fund?
Every organisation claims to experiment, test and learn. So I ask one question: how much money are you deliberately allowed to lose this year while discovering that an important assumption was wrong? The room usually goes quiet.
Real experiments cost money, time, attention and political capital. Mental Sandboxing lets an idea fail in the room before it fails expensively in the market. You can test the idea that would be insane to fund — the AI-native competitor, the collapsing margin, the regulatory shock nobody wants to name. You can ask what happens if your current advantage simply disappears.
Think first. Spend later.
What happens in the session?
The leadership team explores:
- which assumptions may no longer be safe;
- which risks or opportunities are being underestimated;
- which scenarios deserve attention;
- which questions leadership needs to resolve;
- which decisions or experiments should happen next.
This is not brainstorming. It is structured disagreement in service of better decisions.
What changes on Monday morning?
The team leaves with a short account of what surfaced — the Rehearsal Debrief — written to go straight onto the next leadership agenda, not into a filing cabinet. A good session does not leave the team reassured. It leaves them safely uncomfortable, clearer about what matters, and better prepared to act.
Not for everyone
Ask yourself honestly: is your leadership team’s thinking stretched far enough, or is every hour already spoken for by delivery? If you have genuinely got this covered, carry on.
Mental Sandboxing evolved from Bookbuzz, the format Alan Jordan and I ran for years, including a weekly slot on national radio. The book was always the excuse. The room was always the point. We’ve kept the room and sharpened the format for what leadership teams face now.
We are running a small number of Mental Sandboxing sessions this quarter. If your leadership team needs to rehearse what comes next before committing money, reputation and momentum, send me a message.
