Software Engineering for Students A Programming Approach

CHAPTER

This chapter:
In this chapter we identify the significant tasks of software development. The bulk of
this book describes techniques for carrying out these tasks. As part of the story, we
clarify the nature of two important activities that take place throughout software
development – validation and verification.
If you have ever written a program, there a number of activities that you know you
are going to have to carry out, for example, testing. The same is true of larger developments,
but for big programs and large software systems, there are additional elements.
The activities are:
■ a feasibility study
■ requirements engineering
■ user interface design
■ architectural design
■ detailed design
■ programming
■ system integration
■ validation
■ verification (testing)
■ production
The tasks
of software
