Go to Gene Bellinger's insight version with video link This common archetype of systems that include relapse or recidivism allows exploration of the unintended effects of increasing upstream capacity and swamping downstream capacity. The increase in the relapse rate eventually returns to swamp upstream capacity as well.

An infinite number of mathematicians walk into a bar. The first one tells the bartender he wants a beer. The second one says he wants half a beer. The third one says he wants a fourth of a beer. The bartender puts two beers on the bar and says “You guys need to learn your limits.” From Wild About Math

This model shows the Pharmaceutical New Drug Pipeline based on drug release, approval and patent expiry. This pipeline is then linked to patients switching from older drugs to newer drugs based on proven indications and marketing (indication creep).
