In this fable, a poor farmer's goose began laying a solid gold egg every day, and the farmer soon became rich. He also became greedy and figured that the goose must have many golden eggs within her. In order to obtain all of the eggs immediately, he killed the goose. Upon cutting it open he discovered that it was not full of golden eggs. The lesson is that if one attempts to maximize immediate production with no regard to the production capability, the capability will be lost.
Effectiveness is a function of both production and the capacity to produce.
The balance between production and production capability applies to all of them. For example, in an organization the person in charge of a particular machine may increase its immediate production at the expense of maintenance. As a result of the increased output, this person may be rewarded with a promotion. However, the increased immediate output comes at the expense of future production since more maintenance will have to be performed on the machine later. The person who inherits the mess may even be blamed for the inevitable downtime and high maintenance expense.
