Software requirements for engineering and scientific applications are almost always computational and possess an advanced mathematical component. However, an application that calls for calculating a statistical function, or performs basic differentiation of integration, cannot be easily developed in C++ or most programming languages. In such a case, the engineer or scientist must assume the role of software developer.
Software Engineering: Chapter 1 - Introduction presents about Software products, FAQs about software engineering, Essential attributes of good software, Software engineering, Importance of software engineering, Software process activities and somethings else.
Chapter 26 - Software cost estimation. In this chapter, the learning objectives are: To introduce the fundamentals of software costing and pricing, to describe three metrics for software productivity assessment, to explain why different techniques should be used for software estimation, to describe the principles of the COCOMO 2 algorithmic cost estimation model.
PCWorld is a global computer magazine published monthly by IDG. It offers advice on various aspects of PCs and related items, the Internet, and other personal-technology products and services. In each publication, PCWorld reviews and tests hardware and software products from a variety of manufacturers, as well as other technology related devices such as still and video cameras, audio devices and televisions.
The quality of a product is commonly defined by its ability to satisfy stakeholder needs
and expectations. Therefore, it is important to find, select, and plan the content of a
software product to maximize the value for internal and external stakeholders. This
process is traditionally referred to as requirements engineering in the software industry,
while it is often referred to as product management in industries with a larger market
Nowadays, Software Product Line (SPL) is considered to be one of the most popular
technical paradigms and emerging methodologies in developing software products.
The SPL consists of two main processes: the domain-engineering process and the
application-engineering process. Collecting software assets regarding a specific
business area falls within the domain-engineering process
Software has become critical to advancement in almost areas of human endeavour. However, there are serious problems in cost, timelines, maintenance and quality of many software products.
Software engineering has the objective of solving the problems of software by producing good quality, maintainable software, on time, within budget.
The objective of this chapter is to introduce the range of software verification and validation (V&V) activities and a rationale for selecting and combining them within a software development process, view the “big picture'' of software quality in the context of a software development project and organization.
This chapter presents some basic concepts in models of software and some families of models that are used in a wide variety of testing and analysis techniques. The fundamental concepts and trade-offs in the design of models is necessary for a full understanding of those test and analysis techniques, and is a foundation for devising new techniques and models to solve domain-specific problems.
In lecture Software testing and analysis - Chapter 10, you will: Understand the rationale for systematic (nonrandom) selection of test cases; understand why functional test selection is a primary, base-line technique; distinguish functional testing from other systematic testing techniques.
In this chapter, we begin with functional tests based on specification of intended behavior, add selected structural test cases based on the software structure, and work from unit testing and small-scale integration testing toward larger integration and then system testing.
The essential characteristics of system testing are that it is comprehensive, based on a specification of observable behavior, and independent of design and implementation decisions. Independence in system testing avoids repeating software design errors in test design. Acceptance testing abandons specifications in favor of users, and measures how the final system meets users' expectations. Regression testing checks for faults introduced during evolution.
Chapter 16 – Software reuse. The objectives of this chapter are to introduce software reuse and to describe approaches to system development based on large-scale system reuse. When you have read this chapter, you will: understand the benefits and problems of reusing software when developing new systems; understand the concept of an application framework as a set of reusable objects and how frameworks can be used in application development.
The following will be discussed in this chapter: The roadmap to building high quality software products is software process; software processes are adapted to meet the needs of software engineers and managers as they undertake the development of a software product; a software process provides a framework for managing activities that can very easily get out of control;...
Chapter 2 – Software processes. The objective of this chapter is to introduce you to the idea of a software process a coherent set of activities for software production. When you have read this chapter you will: understand the concepts of software processes and software process models; have been introduced to three generic software process models and when they might be used; know about the fundamental process activities of software requirements engineering, software development, testing, and evolution;...
Chapter 18 - Software reuse. The learning objectives for this chapter include: To explain the benefits of software reuse and some reuse problems, to discuss several different ways to implement software reuse, to explain how reusable concepts can be represented as patterns or embedded in program generators, to discuss COTS reuse, to describe the development of software product lines.

This preface describes the intended audience, the organization of this guide, and the text and command conventions used throughout the guide. The preface includes the following topics:...
Unfortunately, much of what has been written about software engineering comes from an academic perspective which does not always address the everyday concerns that software developers and managers face. With decreasing software budgets and increasing demands from users and senior management, technology directors need a complete guide to the subject of software engineering. The successor to the bestselling Software Engineering Productivity Handbook, this book fulfills that need.
The relationship between the quality of a product and the organization responsible
for the development of that product is multidimensional. The relationship depends
upon many factors such as the business strategy and business structure of the organization,
available talent, and resources needed to produce the product. It also
depends upon the combination of activities selected by the organization to achieve
the desired product quality.
