ICT 114 midterms part 2

Question 1

also called process model
a descriptive and diagrammatic representation of the software life cycle
captures the order in which the activities are to be undertaken

Answer 1

LIFE CYCLE MODEL

Question 2

The most obvious way to develop software.
Though tis model is elegant and intuitively obvious, it is not a practical model in the sense that it cannot be used in actual software development projects.

Answer 2

CLASSICAL WATERFALL MODEL

Question 3

This study is to determine whether it would be financially and technically feasible to develop the product.

Answer 3

Feasibility study

Question 4

This phase is to understand the exact requirements of the customer and to document them properly.

Answer 4

Requirements analysis and specification-

Question 5

This phase is to transform the requirements specified in the Software Requirement Specifications document into a structure that is suitable for implementation in some programming language.

Answer 5

Design

Question 6

Two distinctly different design approaches are available:

Answer 6

traditional design approach and the object-oriented design approach.

Question 7

this consists of two different activities; first a structured analysis of the requirements specification is carried out where the detailed structure of the problem is examined.

Answer 7

Traditional design approach

Question 8

In this technique, various objects that occur in the problem domain and the solution domain are first identified, and the different relationships that exist among these objects are identified.

Answer 8

Object-oriented design approach

Question 9

The purpose of the coding phase (sometimes called the implementation phase) of software development is to translate the software design into source code.

Answer 9

Coding and unit testing

Question 10

Integration of different modules is undertaken once they have been coded and unit tested. During the integration and system testing phase, the modules are integrated in a planned manner.

Answer 10

Integration and system testing:

Question 11

when all the modules have been successfully integrated and tested.

Answer 11

System Testing

Question 12

System testing usually consists of three different kinds of testing activities:
It is the system testing performed by the development team.

It is the system testing performed by a friendly set of customers.

It is the system testing performed by the customer himself after the product delivery to determine whether to accept or reject the delivered product.

Answer 12

A testin
B testing
and
Acceptance testing

Question 13

of a typical software product requires much more than the effort necessary to develop the product itself.

Answer 13

Maintenance

Question 14

Maintenance involves performing any one or more of the following three kinds of activities:

Answer 14

Corrective maintenance
perfective maintenance
and
adaptive maintenance

Question 15

Correcting errors that were not discovered during the product development phase.

Answer 15

corrective maintenance.

Question 16

Improving the implementation of the system, and enhancing the functionalities of the system according to the customer’s requirements.

Answer 16

perfective maintenance.

Question 17

Porting the software to work in a new environment. For example, porting may be required to get the software to work on a new computer platform or with a new operating system.

Answer 17

This is called adaptive maintenance.

Question 18

Developed to overcome the major shortcomings of the classical waterfall model
provide feedback paths for error correction when detected later in a phase.

Answer 18

ITERATIVE WATERFALL MODEL

Question 19

a ‘toy’ implementation of the system.
usually exhibits limited functional capabilities, low reliability, and inefficient performance compared to the actual software.

Answer 19

PROTOTYPING MODEL

Question 20

During the first quadrant, it is needed to identify the objectives of the phase.
Examine the risks associated with these objectives.

Answer 20

First quadrant (Objective Setting)

Question 21

A detailed analysis is carried out for each identified project risk.
Steps are taken to reduce the risks. For example, if there is a risk that the requirements are inappropriate, a prototype system may be developed.

Answer 21

Second Quadrant (Risk Assessment and Reduction)

Question 22

Develop and validate the next level of the product after resolving the identified risks

Answer 22

Third Quadrant (Development and Validation)

Question 23

Review the results achieved so far with the customer and plan the next iteration around the spiral. * Progressively more complete version of the software gets built with each iteration around the spiral

Answer 23

Fourth Quadrant (Review and Planning)

Question 24

The spiral model is called a

Answer 24

meta model

Question 25

refers to a development life cycle designed to give much faster development and higher quality systems than the traditional life cycle

Answer 25

Rapid Application Development

Question 26

Is an incremental and iterative process of software development. It defines each iteration’s number, duration, and scope in advance. Every iteration is considered a short “frame” which mostly lasts from two to four weeks.

Answer 26

Agile Model

Question 27

In Agile development, self-organization and motivation are important, as are interactions like co-location and pair programming.

Answer 27

Individuals and interactions

Question 28

Demo working software is considered the best means of communication with the customers to understand their requirements, instead of just depending on documentation.

Answer 28

Working software

Question 29

As the requirements cannot be gathered completely in the beginning of the project due to various factors, continuous customer interaction is very important to get proper product requirements.

Answer 29

Customer collaboration

Question 30

Agile Development is focused on quick responses to change and continuous development.

Answer 30

Responding to change
