Almost any device today has software on it. This includes laptops, Ultrabooks, cell phones, TV sets, Set-Top-Boxes, Microwave Ovens, Cars, Medical Devices, etc. Software is created by software companies and software developers. I have seen only a few software companies who really consider all the elements of software. Most times understanding the system is the realm of the architect and is based on some unique art. Whenever I hear "art", it means that we just don't have the patterns written down yet. This is why I am publishing this post.
