SDM 2 - Stages of SDLC (Part 1)

Question 1

What is Preliminary Analysis?

Answer 1

Starts when a problem within the existing system us forwarded to a system analyst to investigate. Ends when the system analyst produce a preliminary report to the management on the identified problem and the fesibility of the project to solve to problem

Question 2

What is the purpose of preliminary analysis?

Answer 2

To formulate problem statement and to investigate on feasibility

Question 3

What are the 4 things to analyst in a feasibility study

Answer 3

Operational, Economic, Technical and Schedule

Question 4

What report is submitted by the system analyst after preliminary investigation?

Answer 4

Preliminary Investigation Report

Question 5

When does the analysis start?

Answer 5

When the management gives the go-ahaead to develop the system

Question 6

What is the process of analysis?

Answer 6

The process involves information gathering and critical analysis of the root problem of status quou, then propose the accurate solution

Question 7

What document is submitted after the analysis?

Answer 7

System requirement document that will serve as main blueprint for the development team

Question 8

Why do we need analysis?

Answer 8

To provide a detailed structure of what exactly is the root problem to solve and Provide exact requirements demanded by the organization for the new system to deliver

Question 9

How do we analyse?

Answer 9

1. Information gathering from the users of current system and the system itself
2. Analysis of gathered information and recording the data

Question 10

What is in the system requirement document?

Answer 10

• Formal statement problem
• Logical models
  -System requirement specification (SRS)

Question 11

What are the techniques to gather information? IMPORTANT

Answer 11

Interviews, Questionnaires, Sampling, Surveys, Observations, Document Reviews

Question 12

What software do we use for the analysis?

Answer 12

CASE - Computer Aided Systems Engineering
Spreadsheet
Word Processor
Database
Presentation Graphics

Question 13

What are the objectives of System Design?

Answer 13

Practicality, Efficient, Optimization, Accuracy, Reliability, Scalable

Question 14

What are the 2 phases in the design stage?

Answer 14

Logical design and physical design

Question 15

What are the purposes of system design?

Answer 15

• Production of the graphical models of the new system, complete with the relationship between the components of new system
• It will also include detailed specifications of the hardware and software in the system, database and data structure, final feasibility reports and the schedule to start the implementation phase

Question 16

What is logical design?

Answer 16

Is the design of the blueprint of the system

Question 17

What is in the logical design?

Answer 17

Graphical models of the system and the specifications of the components used in the model

Question 18

What are the models that are commonly used? in logical design

Answer 18

Data Flow Diagram (DRD) and Entity Relationship Diagram (ERD)

Question 19

What is DRD?

Answer 19

It describes how data is being transferred in and out of the system

Question 20

What is ERD?

Answer 20

It describes how each component in the system relate to each other

Question 21

What is physical design?

Answer 21

Is the design of the actual components of the system - Hardware,software,user interface, data output format and testing data
