A passenger aircraft is composed of several millions of parts and requires thousandsof persons to assemble. A four-lane highway bridge is another example of complexity.The ?rst version of Word for Windows, a word processor released by Microsoftin1989, required 55 person-years, resulted into 249,000 lines of source code, and wasdelivered 4 years late. Aircraft and highway bridges are usually delivered on time andwithin budget, whereas software is often not. Discuss what are, in your opinion, thedi?erences between developing an aircraft, a bridge, and a word processor thatwould cause this situation.ReplyAn aircraft with several million parts and a four-lane highway bridge are unimaginablycomplex. However, unlike aircrafts and bridges, software is intangible and hard tovisualize, making it the most complex artifact. A large software product comprises ofso many bits and pieces such that each and every one having a designated task(Marsic, 2012}. One ?ipped bit can jeopardize the entire course of a program.
