What short incentives are for
Commission handles the ongoing job. Short incentives handle something specific and temporary: a collections backlog, a new product nobody is mentioning, a quiet month before a festival season, a set of dormant accounts nobody wants to call. If the thing you are trying to fix is permanent, an incentive is the wrong instrument and the commission plan needs changing instead.
That framing prevents the most common mistake, which is running a monthly revenue contest indefinitely. Within a few months it becomes part of the expected compensation, stops changing behaviour, and cannot be removed without it feeling like a pay cut.
