That's one of the reasons Ada isn't more widely used. If we compare SW to HW, we find in HW that a design is created, prototyped, and one or more production exemplars are created by the designers. The item then goes into production, and the produced items are distributed. In SW, a design is created and a production exemplar is created by the designers. The SW then goes into production, which is the process of burning and boxing CDs, packaging the SW for download from the net, or the like. So far, very similar to HW. The cost of designing the SW and creating that production exemplar is high, but the cost of production is not. SW development is a design activity, not a production activity. > Only if the development cost can be amortized over an infinite number of > sales or licences or support contracts.
