Generic View of Software Engineering● Engineering meliputi kegiatan analisis, desain, konstruksi,

verifikasi, dan manajemen kesatuan teknik atau sosial.

● Pertanyaan-pertanyaan yang harus dimunculkan dan dijawab:

* Apa masalah yang akan dipecahkan?

* Karakteristik entitas yang manakah yang dipakai untuk menyelesaikan masalah

tersebut?

* Bagaimanakah entitas (dan pemecahan) tersebut diadakan?

* Bagaimanakah entitas tersebut dibangun?

* Pendekatan apakah yang akan dipakai untuk menemukan kesalahan-kesalahan

yang dibuat dalam desain dan kontruksi dari entitas tersebut?

* Bagaimanakah entitas tersebut ditopang selama proses adaptasi yang lama, pada

saat koreksi, serta ketika perbaikan dibutuhkan oleh para pemakai entitas

tersebut?

General Phase to Software Engineering

*Definition phase berfokus pada ‘apa’ (what):

* informasi yang akan diproses

*fungsi dan perfomance yang dibutuhkan

*tingkah laku sistem yang diharapkan

* interface yang akan dibangun

*batasan sistem yang sukses

General Phase to Software Engineering

*Development phase berfokus pada ‘bagaimana’ (how):

*data dikonstruksikan

*fungsi-fungsi diimplementasikan

*detail prosedur akan diimplementasikan

* interface dikarakterisasi

*rancangan akan diterjemahkan ke dalam pemrograman

*pengujian dilakukan

General Phase to Software Engineering

*Maintenance phase berfokus pada ‘perubahan’

(change):

*dihubungkan dengan koreksi kesalahan

*ketika lingkungan perangkat lunak berkembang

*sehubungan dengan perubahan kebutuhan pelanggan

Changes in Phase Development

*Correction (Koreksi)

*Membetulkan cacat atau kerusakan

*Adaptation (Adaptasi)

*Modifikasi perangkat lunak karena perubahan kebutuhan

fungsional original (CPU, OS, aturan bisnis, karakteristik produk

eksternal, dll)

Changes in Phase Development

*Enhancement (Perkembangan)

*Memperluas perangkat lunak sehingga melampaui kebutuhan

fungsi originalnya

*Prevention (Pencegahan)

*Pencegahan sebagai antisipasi perubahan karena usia perangkat

lunak

Umbrella Activities

*Software project tracking and control

*Formal technical reviews

*Software quality assurance

*Software configuration management

*Document preparation and production

*Reusability management

*Measurement

*Risk management

Characteristics of Maturity levels

Level 1

InitialProcesses Unpredictable, poorly

controlled and reactive

Level 2

ManagedProcesses characterized for projects

and is often reactive

Level 3

Defined

Processes characterized for

organization and is proactive(Projects tailor their processes from

organization’s standards)

Level 4

Quantitatively Managed

Processes measured and

controlled

Level 5

Optimizing

Focus on process

improvement

SOFTWARE DEVELOPMENT LIFE CYCLE

SOFTWARE DEVELOPMENT LIFE CYCLE

“Sekumpulan Kegiatan dan keterhubungannya satu sama

lain untuk mendukung pembangunan dari sebuah

perangkat lunak”.

Pengertian

Pertanyaan Seputar SDLC

1. Aktifitas mana yang harus dipilih dalam pembangunanperangkat lunak?

SDLC berisi proses yang bukan untuk dipilih tapi untukdilakukan secara keseluruhan

Pertanyaan Seputar SDLC

2. Hubungan antar aktifitas dalam SDLC?

Hasil dari kegiatan sebelumnya mempunyai pengaruh yang

sangat besar untuk kegiatan berikutnya

Pertanyaan Seputar SDLC3. Bagaimana cara menjadwalkan kegiatan pada SDLC?

Penjadwalan kegiatan SDLC dibahas dalam ilmu Manajemen

Proyek (Project Management) dan tidak dibahas pada RPL

SOFTWARE DEVELOPMENT LIFE CYCLE

1. Planning: Why build the system?

o System request, feasibility analysis, project size estimation

2. Analysis: Who, what, when, where will the system be?

o Requirement gathering, business process modeling

3. Design: How will the system work?

o Program design, user interface design, data design

4. Implementation: System construction and delivery

o System construction, testing, documentation and installation

SOFTWARE DEVELOPMENT LIFE CYCLE

1. Identifying business value (System Request)

o Lower costs

o Increase profits

2. Analyze feasibility

o Technical Feasibility

o Economic Feasibility

o Organizational Feasibility

3. Estimating the size of project

(System Proposal)

SOFTWARE DEVELOPMENT LIFE CYCLE

1. Requirement gathering by answering the questions:

o Who will use the system?

o What will the system do?

o When will it be used?

2. Investigate the current system

3. Identify possible improvements

4. Develop a concept for new system

(Business Process Model)

SOFTWARE DEVELOPMENT LIFE CYCLE

1. Program Design (DFD)

o What programs need to be written

o Exactly what each program will do

2. User Interface Design

o How users interact with system

o Forms / reports used by the system

3. Data Design (ER Diagrams)

o What data is to be stored

o What format the data will be in

o Where the data will be stored

(System Specification)

SOFTWARE DEVELOPMENT LIFE CYCLE

• Construction

o New system is built and tested

o Often testing is the longest part

• Testing

o Unit Testing

o Integration Testing

o System Testing

o User Acceptance Test

• Installation

o Old system is turned off

o New system is turned on
