Software Process
1.1 Introduction
Software engineering is the establishment and sound engineering principles applied to obtain
reliable and efficient software in an economical manner
Software engineering includes process, management techniques, technical methods, and
the use of tool. While building any software, the software process provides the interaction
between user and developer. In this chapter we will understand the basic concept of process and
process models. We will discuss how to use various life cycle models for building qualitative
software in an economic manner. Finally we will focus on system engineering.
1.1.1 Layered Technology
Software engineering is a layered technology. Any software can be developed using these
.layered approaches. Various layers on which the technology is based are quality focus
layer, process layer, methods layer, tools layer.
A disciplined quality management is a backbone of software engineering technology.
Process layer is a foundation of software engineering. Basically, process defines the
framework for timely delivery of software.
In method layer the actual method of implementation is carried out with the help of
requirement analysis, designing, coding using desired programming constructs and
testing.
Software tools are used to bring automation in software development process.Thus software engineering is a combination of process, methods, and tools for development of
quality software.
1.2 Software Process
Software process can be defined as the structured set of activities that are required to develop the
software system.
The fundamental activities are
Specification
Design and implementation
Validation
Evolution
A software process model is an abstract representation of a process. It presents a description
of a process from some particular perspective.
1.2.1 Common Process Framework
The process framework is required for representing the common process activities. It is as shown
below.As shown in figure the software process is characterized by process framework activities,
task sets and umbrella activities.
Process Framework Activities
Communication
o By communicating customer requirement gathering is done.
Planning - Establishes engineering work plan
