Qus:1 What is The Need for a
Business Model in Software Engineering?
Answer: Software engineering faces several
dilemmas. It has comprehensive goals, but limited tools. It demands broad
perspectives, but depends on narrowly focused practitioners. It places a high
premium on quality, but often has insufficient inputs to its problem-solving
process. As a field, software engineering has yet to define theories and
frameworks that adequately combine the
Qus:2 a)
What are the different levels of software reuse?
b) What are the aspects of software
reuse?
Answer: The design process in most
engineering disciplines is based on component reuse. Mechanical or electrical
engineers do not specify a design in which every component has to be
manufactured specially. They base their design on components that have been
tried and tested in other systems. These components obviously include small
components such as nuts and
Qus:3 What is meant by Architectural
Design? Explain.
Answer: Large systems can be decomposed
into sub-system that provides some related set of services. The initial design
process of identifying this subsystem and establishing a framework for
sub-system control and communication is called Architectural design.
Architectural design comes before detailed system
specification, it should not include any design information.
Qus:4 What are the different phases
of Rapid Application Development model?
Answer: Rapid Application Development (RAD)
is an incremental software development process model that emphasizes an
extremely short development cycle. The RAD model is a high speed adaptation of
the linear sequential model in which the rapid development is achieved by using
component-based construction. If requirements are clear and well understood and
the
Qus:5 Explain Top-down Integration
Testing and Bottom-up Integration Testing.
Answer: Top-down integration testing is an
incremental approach to construction of program structure. Modules are
integrated by moving downward through the control hierarchy, beginning with the
main control module (main program). Modules subordinate (and ultimately
subordinate) to the main
Qus:6 What do you mean by Customer
Driven software development?
Answer: It is a truism that, in a
customer-focused economy, software engineering must also be customer driven.
This section considers some characteristics and techniques typical of a
customer-driven software development environment. These include:
Customer-driven
development is requirements intensive and features driven. Because customer
needs are the highest priority, they
