2-System development Life Cycle (SDLC)

Question 1

What is SDLC

Answer 1

A framework for deciding what software should do, building it accordingly, performing testing to verify features, placing it in production, providing support, and maintaining it after initial implementation.

Question 2

Phases of the SDLC - called waterfall-style framework

Answer 2

1-Feasibility Study
2-Requirements definition
3-Design
4-Development
5-Testing
6-Implementation
7-Post-implementation

Question 3

A gate process approach to SDLC

Answer 3

Formal review at the conclusion of each phase of the SDLC before a move to the next phase is permitted

Question 4

Request For Proposal (RFP)

Answer 4

Activity used to communicate requirements and solicit proposals from vendors.

Question 5

Design effort

Answer 5

It should be a top-down process.

Question 6

Why should internal IT auditors be included in the design review

Answer 6

So that they can confirm whether the application design will result in an application whose integrity can be confirmed through auditing.

Question 7

Activities included in the development phase

Answer 7

1-Coding the application
2-Developing program-and system -level documents
3-Developing user procedures
4-Working with users

Question 8

Debugging

Answer 8

The process of testing software to make sure that it operates properly and is free of defects.

Question 9

Source Code Management

Answer 9

A source code repository tool, for example, has purposes such as :

1-Protection - Access control so that only authorized personnel are permitted to access application code

2-Control - Check out and check in function to ensure the integrity of the application’s source code.

3-version control - Trach change made from version to version

4-recordkeeping - Maintain a record for check-out, check-in, modification to the source code

Question 10

Stage of testing in a software development project

Answer 10

1-Unit testing - performed during the coding phase by the developer.

2- System Testing- includes interface testing to confirm that the application is communicating properly with other applications.

3- Functional Testing - Primarily concerned with the verification of functional requirements that were developed earlier in the application project.

4-User Acceptance Testing (UAT) - Before business formally approve and begin using a new applicaton
