  Michael Grieves has proposed that the focus on information should be what it does as opposed to defining what it is. Grieves has proposed that information can be substituted for wasted physical resources, time, energy, and material, for goal-oriented tasks. Goal-oriented tasks can be divided into two components: the most cost-efficient use of physical resources: time, energy and material, and the additional use of physical resources used by the task. This second category is by definition wasted physical resources. Information does not substitute or replace the most cost-efficient use of physical resources but can be used to replace the wasted physical resources. The condition that this occurs under is that the cost of information is less than the cost of the wasted physical resources. Since information is a non-rival good, this can be especially beneficial for repeatable tasks. In manufacturing, the task category of the most cost-efficient use of physical resources is called lean manufacturing.
