Pengenalan Software Engineering
(Rekayasa Perangkat Lunak)

#1 [ S O F T W A R E ]

http://flickr.com/photos/striatic/2326860/

a collection of computer programs, procedures and documentation
that perform some tasks on a computer system
~ Wikipedia.org

System Software
device drivers, operating systems,
servers, utilities, window manager

http://www.flickr.com/photos/mrqf/1150458179/
Programming Software
compilers, debuggers, interpreters,
linkers, text editors ~ IDE

http://www.flickr.com/photos/21160667@N07/2056870120/
Application Software
business/office, education, games
entertainment dll.

#3 [ S O F T W A R E E N G I N E E R I N G ? ]

a systematic, disciplined, quantifiable approach to the
development, operation, and maintenance of software
~ Wikipedia.org

software development process...
software life cycle...

#4 [ A K T I F I T A S S O F T W A R E E N G I N E E R I N G ]

apapun metodologinya, aktifitas di dalamnya
kurang lebih tetap sama...

Analogi :
Apapun strateginya (4­4­2, 4­5­1), gayanya (total football,joga
bonito, kick n rush, cattenacio)... aktivitas di lapangan hijau
tetaplah menendang bola, mengoper, menangkap bola dst.

apapun metodologinya, aktifitas pengembangan
perangkat lunak umumnya...

1. Requirements
mendapatkan kejelasan bisnis proses dari
user melalui komunikasi langsung
output: dokumen wawancara (waterfall),
diagram use case (UML), user stories (XP)

http://www.flickr.com/photos/merydith/3215847513/
2. Modelling
menerjemahkan bisnis proses ke bentuk
model atau diagram (UML, DFD,
Flowchart/flowmap, ER).

http://www.flickr.com/photos/samuraislice/2985906586/
3. Design
merencanakan rancangan software agar
fault­tolerance, compatibility, extensibility,
reliability, maintainability, availability,
usability → contoh: desain arsitektur
( client­server? N­tier? MVC?), platform dll.

http://www.flickr.com/photos/tobanblack/3251282019/
4. Implementation
aksi logic dan programming, tapi aktivitas
lain selain engineering bisa muncul juga di
sini (science, mathematics dan seni)

http://www.flickr.com/photos/pgautier/1298109082/
5. Testing
identify the correctness, completeness,
security and quality (data sample,
simulation, alpha test, beta test)

http://www.flickr.com/photos/smart_growth/2454419537/
6. Deployment
instalasi, aktivasi, update, adaptasi dan
sosialisasi, (membuat software kita siap
digunakan oleh user)
++ issue: maintenance...

selain aktifitas standar di atas, seperti halnya peran
medic & wasit di sepak bola.. ada aktifitas pendukung lain
yang menopang poin 1­6 di atas...

X. Supporting Disciplines
dokumentasi
project management
quality assurance dll.

CONTEXT DIAGRAM (CD)
­ represent all external entities that may interact with a system
­ lingkaran (sistem) + kotak (entity) + panah + input output

DATA FLOW DIAGRAM (DFD)
­ detailing context diagram
­ level kedalaman idealnya 1­3
­ hukum: data/info yang masuk = data/info yang keluar

CONTEXT DIAGRAM
DFD LEVEL 1

ENTITY RELATIONSHIP DIAGRAM (ERD)
­ abstract and conceptual representation of data
­ skema & modelling database

USE CASE DIAGRAM
­ description of a system’s behaviour / responds to a request
­ describes \"who\" can do \"what\" with the system
­ user point of view
­ part of UML tools

FLOW MAP DIAGRAM
­ advance flow chart: object movement by location/position

1. Waterfall
paling konvensional
flowing steadily downwards
serial banget... kaku...

http://www.flickr.com/photos/gigaboss/100381027/
membuat prototype atau mock­up
2. Prototyping

http://www.flickr.com/photos/slr/11147904/
3. Spiral
kombinasi top­down & bottom­up
cikal bakal iterative

http://www.flickr.com/photos/rutlo/3339656017/
4. Rapid App. Dev.
fast development & smaller/modular
(karena ada RAD tools yang OK)

http://www.flickr.com/photos/lenore­m/2400412112/
5. Iterative
basic concept, banyak menjadi bagian
metode lainnya...

RUP, Rational Unified Process...
­ Divisi IBM
­ UML
­ Rational Rose

XP, extreme programming...
­ day­to­day practices for developers and managers
­ more responsive to customer needs (agile)
­ pragmatis

Agile Software Development...
XP+Scrum+DSDM+Crystal+Pragmatic+FDD = agile manfesto
­ customer satisfaction by rapid, continuous delivery of useful software
­ working software is delivered frequently (measure of progress)
­ late changes in requirements are welcomed
­ close, daily cooperation between business people and developers
­ face­to­face conversation is the best form of communication
­ projects are built around motivated individuals, who should be trusted
­ continuous attention to technical excellence and good design
­ simplicity
­ self­organizing teams
­ regular adaptation to changing circumstances

web development “banget”, pragmatic, representasi → scrum

adaptasi software development methodology “untuk kita” ?
