STRATAGEM is the closest thing to practising McKinsey Solve, with one difference: every debrief explains the chain of consequences your decisions set off, not just whether you got the answer "right."

Most reasoning tests grade you with a percentile and leave. STRATAGEM puts you inside scenarios that behave like real systems — and explains every cascade your decisions set off.
Investigate, hypothesise, allocate, and watch what plays out. No multiple choice. No timer pressure tricks.
Every outcome is reconstructed as a chain: your decision → consequence → secondary effect → final outcome.
The Strategic Aptitude Rating — rolled up from outcome quality, information efficiency, decisions, and risk.
Twenty-four species, four habitat zones, a 60-tick horizon. Probe what you can't see, pick a viable roster, and stake your predictions before drought, fire and invasives hit.

Read incomplete intelligence under time pressure, weigh contradictory evidence, commit to a hypothesis, and allocate crews across the basin before conditions shift.

A 20-minute behavioural scenario: read a sustainability mission briefing, rank the team's opening priorities, then work through ~12 branching decisions where each choice reshapes what the team faces next. No numbers, no calculator — pure judgement.

Every stage is a real decision surface. Here's what you'll actually be using.




A single SAR score, four axis scores, your strongest and weakest moves, and a causal walkthrough of the cascade you set off.
Protecting Wolf at tick 30 would likely have prevented the keystone collapse. Deer browsing pressure would have remained lower, Aspen regeneration would have held, and the late-stage cascade would not have removed Beaver from the wetland — projected SAR +18.
