Time as a Unique Resource
Because all inputs are human modulated, they are all subject to the one key resource – Time. Humans are inevitably a slave to time. Therefore, time is really the ultimate resource. And it is unlike other resources. Sometimes you can “crash” a project by adding people, you might increase heat, or the flow of a chemical, deliver two trucks of cement instead of one. But you cannot add time. Extending the delivery date of work is not the same thing as adding more time, because you can’t increase a quality of the delivery by increasing the time invested, the relationship is the opposite. “Adding time” in the sense of delaying the delivery date is decreasing a factor of quality that describes the work.
