According to the standard IEEE 982, the functions of a measure of software product/process can be provided by Halstead's so called Software Science Measures. We had built a new approach in this area earlier, so that "energy of specifications" and "work of coding" arose in the new theory that is inherited the old Software Science. In particular we obtained theoretical ability to test reliability of software development. Practical using aspects of the new measure are investigated on example of development of a real software product. We select one AdaCore product which is distributed under open source license. Our example of calculation the metric uses sequence of sources that was produced on different stages of this product development.
