A four-lane highway bridge is another example of complexity. The first version of Word for Windows, a word processor released by Microsoft in 1989, required 55 person-years, resulted into 249,000 lines of source code, and was delivered 4 years late. Aircraft and highway bridges are usually delivered on time and within budget, whereas software is often not. Discuss what are, in your opinion, the differences between developing an aircraft, a bridge, and a word processor that would cause this situation 97 words Permalink | Reply Re: Unit 1 Discussion Assignment by Susan Mills - Friday, 2 February 2018, 5:25 AM CS 2401: Unit 1 – Discussion Post Hello Class, this week’s discussion post tells us to discuss the topic using our own opinion so I am going to take a shot at this week without reading the assignments or doing the other work this week just so that I fully use my opinion and experiences to answer this so that I can compare my understanding later on this week to see what I picked up that I didn’t know or think of related to this problem. I thought about the question this way: 1. An aircraft.
3/28/2018 CS 2401 - AY2018-T3: Unit 1 Discussion Assignment 2/32 An aircraft as mentioned is very complex and must be built to very precise and specific designs and specifications. It uses a very detailed pre-engineered design that has no room for variance, as the slightest variance could cause a major disaster in the sky. It is so critical that it is built using automated machining and tools with many checks and balances that are also always the same. It is this pre-defined exacting requirements that never change and are always the same that keep this project on track and budget. Exact amount and dimension of materials is known, the automated tool timings and checks are also always known, all of this means on-time and on budget is pretty typical. 2. A 4-lane highway bridge The same types of things that keep a plane on track, keep a bridge on track. While a bridge unlike an aircraft don’t get built by the assembly line, its parts typically do, and the engineering has been done time and time again, an arch’s weight to height to load measurements are mathematical formulas used since the Roman Empire and likely before that. It is tried and true and those that run and work construction projects like this are very experience and have built many of these.
