During the New Product Development process, build a system of metrics to monitor progress. Include input metrics, such as average time in each stage, as well as output metrics that measure the value of launched products, percentage of new product sales and other figures that provide valuable feedback.
Work done by a system decreases the internal energy of the system, as indicated in the First Law of Thermodynamics. System work is a major focus in the discussion of heat engines.
The First Law of Thermodynamics states that during any reaction the total energy in the universe remains constant. The Second Law of Thermodynamics states that during any reaction the total useful energy in the universe (the energy that is useful for doing work) will decrease. For example, consider a ball rolling downhill, moving faster and faster.
