Drifting Goals
The “boiled frog”: the gap between desired and actual is closed by lowering the goal — not by raising performance.
Definition
The “Drifting Goals” archetype captures the “boiled frog” phenomenon: a persistent gap between desired and actual performance is closed not by improving performance but by lowering the goal. Each single adjustment is small and seems reasonable — but in aggregate the level of ambition slides imperceptibly yet steadily downward.
Structure
Two competing balancing loops (B) act on the same gap. The first (B) closes it by raising actual performance toward the goal — laborious and slow. The second (B) closes it by lowering the goal toward actual performance — fast and comfortable. Under pressure for quick relief the second loop almost always wins, and the goal drifts downward step by step.
When it applies
The gradual decline of quality standards, the normalization of deviance in safety, chronic budget deficits with an ever-revised “acceptable” level of debt. Whenever goals quietly yield under pressure.
Leverage points
Anchor goals to an absolute external standard or a documented best practice that internal pressure cannot quietly readjust. Make every lowering of the goal an explicit, visible decision that requires justification — because the danger lies precisely in erosion happening unnoticed and undecided.
Examples
A team that softens its definition of “done” a little each sprint until quality becomes meaningless. An organisation that quietly lowers its safety or response-time target after every near miss.
Build this pattern as a causal loop and simulate it.
