Why isn’t it called All About Programming or Software Engineering? After all, isn’t that what software development is? Well, no Programming is a part of software development, but it’s certainly not all of it Likewise, software development is a part of software engineering, but it’s not all of it Here’s the definition of software development. .. about estimation and scheduling The key to iterative development is “live a balanced life – learn some and think some and draw and paint and sing and dance and play and work every day some,”6 or in the software development world, analyze some and design some and code some and test some every day We’ll revisit this idea when we talk about the agile development models Evolving the Incremental Model 7... about professional practice, the ethics and the responsibilities of being a software developer, social issues, privacy, how to write secure and robust code, and the like In short, those fuzzy other things one needs in order to be a professional software developer This book covers many of the topics described for the ACM Computing Curricula 2001 course C292c Software Development and Professional Practice. .. introduction into what software development is all about and what you need to do to write great code It has its own perspective, but that’s a perspective based on 20 years writing code professionally and another 16 years trying to figure out how to teach others to do it Despite the fact that software development is only part of software engineering, software development is the heart of every software project... baseline building and scheduling, managing people, and several other things Software development is the fun part of software engineering So software development is a narrowing of the focus of software engineering to just that part concerned with the creation of the actual software And it’s a broadening of the focus of programming to include analysis, design and release issues 1 Brooks, Frederick “No Silver... software development, but it’s not the whole thing Well, then, isn’t it software engineering? Again, no Software engineering also involves a process and includes software development, but it also includes the entire management side of creating a computer program that people will use Software engineering includes project management, configuration management, scheduling and estimation, baseline building and. .. You’ll begin to understand project management, know some metrics, know how to review work products, and understand configuration management I’ll not cover everything in software development by a long stretch, and we’ll only be giving a cursory look at the management side of software engineering, but you’ll be in a much better position to visualize, design, implement, and test software of many sizes,... how to design and implement programs that solve specific problems By the way, there’s at least one person (besides me) who thinks software development is not an engineering discipline I’m referring to Alistair Cockburn, and you can read his paper, “The End of Software Engineering and the Start of Economic-Cooperative Gaming” at http://alistair.cockburn.us/The+end+of +software+ engineering +and+ the+start+of+economiccooperative+gaming... principles to the development of software. ” What are “engineering principles?” Well, first, all engineering efforts follow a defined process So we’ll be spending a bit of time talking about how you run a software development project and what phases there are to a project All engineering work has a basis in the application of science and mathematics to real-world problems So does software development As... new development tools (say that new web development framework) you’ll uncover limitations you weren’t aware of and side-effects that cause you to have to learn, for example, three other tools to understand them (That web development tool is Python based, requires a specific relational database system to run, and needs a particular configuration of Apache to work correctly.)
