Outline of this presentation

• Software’s Dual Role• Software Characteristic• Generic View of Software Engineering

2

Software’s Dual Role

• Software is a –product–vehicle for delivering a product

3

Software’s Dual Role

• Software is a product–Transforms information • produces, manages, acquires, modifies, displays, or transmits information

–Delivers computing potential of hardware and networks

4

Software’s Dual Role

• Software is a vehicle for delivering a product• Controls other programs –(operating system)

• Effects communications –(networking software)

• Helps build other software –(software tools & environments)

5

Software Characteristics

• Software has some special characteristics–Software is “developed” and not

manufactured”

6

Software Characteristics

– Software has

– Software does NOT wear out (aus)– Software deteriorates (memburuk) due to

discovery of bugs and applying patches

Generic View of SE

• Requirement– Customer Need

• Specification– Software Need

• Design– Model of Software

• Code– Program

9

Generic View of SE

• Test– Make Sure

• Debug– Repair

• Maintain– Life Cycle

10

Generic View of SE

• Requirement– Customer Need

• Find out what the user need• General statement about

– Purpose of System– Resources Availability

» Time» Money» Person

Generic View of SE

• Specification– Software Need

• Create Software Specification• Detail Specification about

– Functionality– H/W & S/W Requirement– etc

12

Generic View of SE

• Design– Model of Software

• Creating a model– Behavioral Model– Structural Model

13

Generic View of SE

• Code– Program

• Create a Program– Base on Model

14

Generic View of SE

• Test– Make Sure

• Process of Verification & Validation– Conformity with Specification

15

Generic View of SE

• Debug– Repair

• Bugs Finding & Reducing– an iterative process with testing
