Effectiveness requires maintaining a balance between production (“P”) and production capability (“PC”). For example, in the parable of the goose that lays the golden egg, the golden egg is the “P,” or the thing that is produced. The goose is the “PC,” the asset that has the capacity to produce. If you are too focused on P and not PC, or, if you do not invest in PC, P will suffer. For example, if you run a machine too intensely, or push your workers too hard, with the intent of producing more, you will eventually find that the product is not as good: the machine will wear out or the employees will perform at substandard levels due to fatigue. P/PC balance means investing in all levels of the production process. The Seven Habits allow for optimal P/PC balance.
