The CUMULATIVE S-CURVE

The cumulative version of the curve can be used to model POPULATION GROWTH as well as the adoption of a NEW PRODUCT. It can also be used to model how advertising spending is related to a response such as awareness.

The S-CURVE model of REWARD [y] vs. EFFORT [x] (of which the ad model is one example) works as follows:

In the lower ranges of x there is very little response on the y axis. This can be thought of as STARTING FRICTION.

Once the x variable reaches and goes beyond the first inflection point (which can be thought of as the THE PRICE of ENTRY), it enters a region known as the SWEET SPOT where effort x is directly proportional to reward y. This is the zone within the curve where effort is most productive.

Effort along the x axis will be proportionately rewarded until we hit the second inflection point. After we pass this point, we enter into the region of DIMINISHING RETURNS. After passing this point, each increase in x will yield progessively less incremental reward in y.

Checking this out against your own experiences of REWARD vs. EFFORT will probably show that this model makes sense. The trick is to fit it to a particular situation, and most importantly, to find the locations of the two INFLECTION POINTS.
