What to do in situations wherein IF-THEN extrinsic rewards are a mistake?

IF-THEN extrinsic rewards have the sole purpose of short term benefits by stimulating desired behavior or compliance for doing routine bound , dreary tasks.

Upon realization that an environment is not suited for IF-THEN rewards , extrinsic rewards should be made unexpected and offered only when the task is complete.

In other words , where IF-THEN awards are a mistake , shift to NOW-THAT rewards.
