Resumen
The article focuses on software intensive systems on which modern society is dependant someway or the other. For the first time, electronic voting technology was used in the U.S. Presidential elections of November 1994. They are an example of the software-intensive systems that every industrialized society increasingly depends on for their basic operations. The systems can be availed in air travel, operating the electric power grid, and filing tax returns. The software-intensive systems are so complex that often it is difficult to understand and control them. Living in a world in which the number and diversity of devices, amount of software, and degree of connectivity in complex systems are all increasing by orders of magnitude, it is essential to have a science of design on which to base the efforts to create these systems. A scientific basis exists for many engineered artifacts, ranging from integrated circuits to airplanes. A more complete definition of a science of design may be found through close examination of the words "science" and "design."
