Master Deep Analytical Questioning

PRISM
Don't outsource your thinking. Practise it. 552 prompt cards that give any team structured strategy sessions straight out of the box.

PRISM puts strategic thinking frameworks into your hands. Open the box and go.
Open the box, pick a recipe card, and run a structured session. No training or facilitator certification needed.
The decks draw on techniques such as key assumptions checks, red teaming, pre-mortems and what-if analysis.
Cards create equal airtime. Quiet voices speak up, dominant voices listen, and the whole room shapes the strategy.
Structured prompts surface assumptions and force clarity on what gut instinct glosses over.
Dedicated decks for biases, assumptions, red teaming, and worst-case thinking stress-test your plans.
552 prompt cards across 11 decks, 43 ready-made recipe guides, and 27 tactical exercises. Designed by The Long Game Project, a business-wargaming practice.
Each colour-coded deck tackles a different thinking challenge - from surfacing hidden biases to stress-testing your boldest plans.

Master Deep Analytical Questioning
Break down complex problems with structured, incisive questions that get past the noise to the root cause.

Uncover & Test Hidden Assumptions
Surface what everyone takes for granted but nobody examines. These cards reveal the hidden beliefs driving your strategy - before they drive it off a cliff.

Spot & Mitigate Biases
Identify the cognitive traps distorting your decisions. From confirmation bias to groupthink, these cards make invisible thinking patterns visible.

Find Inventive Solutions
Break through 'we've always done it this way' thinking. Structured prompts that push teams beyond incremental ideas into genuinely new territory.

Explore Multiple Futures
See around corners before your competition does. Build the foresight your team needs to plan under uncertainty.

Shift Viewpoints, Spot Opportunities
See problems through different lenses. These cards force perspective shifts that reveal blind spots.

Systematically Stress-Test Plans
Expose weaknesses before reality does. Challenge plans, probe vulnerabilities, and build strategies that survive contact with the real world.

Move from vague direction to concrete strategy. These cards take you from knowing what you want to knowing how to get there.

Prepare for Disruption
Explore alternative scenarios before they happen, and decide in advance how your team would respond.
