Software Eng, Roger Presmen
Sophistication and com- plexity can produce dazzling results when a system succeeds, but they can also pose huge problems for those who must build complex systems.
New software-driven industries have arisen and old ones that have not adapted to the new driving force are now threatened with extinction. You apply a software engineering approach. This book presents a framework that can be used by those who build computer software—people who must get it right.
It serves as the basis for modern scientific investigation and engi- neering problem solving. Some of these technologies are targeted at a specific application domain e. Software, in the guise of the now-infamous Y2K bug, would fail and, as a result, stop the world as we then knew it.
The role of computer software has undergone significant change over a time span of little more than 50 years. And yet, people bet their jobs, their comfort, their safety, their entertainment, their decisions, and their very lives on computer software.
It is a key factor that differentiates modern products and services.
As a product, it delivers the computing potential embod- ied by computer hardware or, more broadly, a network of computers that are accessible by local hardware. Osborne [OSB79] characterized a “new industrial revolution. You build computer software like you build any successful product, by apply- ing a process that leads to a high-quality result that meets the needs of the people who will use the product. From the point of view of a software engineer, the work product is the pro- grams, documents, and data that are computer software.
As the vehicle used to deliver the product, software acts as the basis for the control of the computer oper- ating systemsthe communication of information networksand the creation and control of other programs software tools and environments.
Read the remainder of this book, select those ideas appli- cable to the software that you build, and apply them to your work. It is embedded in systems of all kinds: It better be right. It is a product and, at the same time, the vehi- cle for delivering a product. Because it affects nearly every aspect of our lives and has become pervasive in our commerce, our culture, and our everyday activities.
What is the work product? Computer software has become a driving force. It is the engine that drives business decision making.

Software engineers build it, and virtu- ally everyone in the industrialized world uses it either directly or indirectly. What are the steps?
It encom- passes programs that execute within a computer of any size and architecture, documents that encompass hard-copy and virtual forms, and data that combine numbers and text but also includes representations of pictorial, video, and audio information. Whether it resides within a cellular phone or operates inside a sofware computer, software is an information transformer—producing, manag- ing, acquiring, modifying, displaying, or transmitting information that can be as sim- ple as a single bit or as complex as a multimedia presentation.
Engenharua books published during the s and s provide useful historical insight into the changing perception of computers and software and their impact on our culture. As its importance grows, the software community continually attempts to develop tech- nologies that will make it easier, faster, and less expensive to build high-quality com- puter programs.
And as we move into the twenty-first century, it will become the driver for new advances in everything from elementary education to genetic engineering. As the softwarf began, Toffler [TOF90] described a “power shift” in which old power structures governmental, educational, industrial, economic, and military disinte- grate as computers and software lead to a “democratization of knowledge.

Engenharia de Software 3. However, we have yet to develop a software technol- ogy that does it all, and the likelihood of one arising in the future is small. The technology encompasses a softwxre, a set of methods, and an array of tools that we call software engineering. Software is virtually inescapable in a modern world. Software transforms personal data e.
Software delivers the most important product of our time—information. Computer software is the product that software engi- neers design and build.
