You did a great job on contrasting the software from bridges and planes. It was easy to tell what the di²erent requirements mean in the development process for both and how software can become complex in regards to a project. 45 words Permalink | Show parent | Reply Re: Week 1 Discussion Question by Godwin Opelikwu - Saturday, 2 February 2019, 4:56 AM A passenger aircraft is composed of several millions of parts and requires thousands of 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 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 di²erences between developing an aircraft, a bridge, and a word processor that would cause this situation. Reply An aircraft with several million parts and a four-lane highway bridge are unimaginably complex. However, unlike aircrafts and bridges, software is intangible and hard to visualize, making it the most complex artifact. A large software product comprises of so many bits and pieces such that each and every one having a designated task (Marsic, 2012}. One ³ipped bit can jeopardize the entire course of a program. Programmers on the other hand don’t have superhuman abilities to code an error free software in one straight fashion without a test design. Hence, the time lag. Word processor for windows in 1989 was the ±rst version, being an inventive software, the possibility exists of having little or no point of reference. On the contrary, engineers use actual data from previous bridges and aircraft to estimate the budget and schedule for new bridge and aircraft (Hall, 2004). Many bridges and aircraft are just improvement base upon previous versions, this decreases the bulk of the overall level of commitment devoted to software design. bridges and aircraft have a well-structured guidelines and technologies to drive the process, whereas software design and implementation depends on the designer’s capabilities.

With software and apps so ubiquitous today wouldn't the software designers have a better understanding of what user or stakeholders would want?
