Pengantar

Peranan Sistem Informasi bagi Manajemen

Manajemen membutuhkan informasi untuk mendukung pengambilan keputusan yang akan dilakukan.

Sumber informasi untuk pengambilan keputusan manajemen bisa didapatkan dari informasi internal maupun exsternal.

Kegiatan Manajemen

Kegiatan manajemen dihubungkan dengan tingkatan di dalam organisasi. meliputi manajemen tingkat atas, menengah dan bawah.

Kegiatan manajemen utk masing-masing tingkatan:

Perencanaan Strategi (Strategic planning)

Pengendalian manajemen (management control)

Pengendalian operasional (operational control)

Pengembangan Sistem ( Systems Development )

Dapat berarti Memperbaiki sistem yang telah ada.

menyusun suatu sistem yang baru untuk mengganti sistem yang lama secara keseluruhan.

Alasan Pengembangan Sistem

Adanya permasalahan-permasalahan yang timbul, al:

Ketidak beresan

Pertumbuhan organisasi

Untuk meraih kesempatan (Oportunities)

Adanya instruksi-instruksi (directives)

Tujuan pengembangan sistem

performance

Information

Economy

Control

Efficiency

Service

Sistem dikembangkan utk manajemen

Sistem yang dikembangkan adalah investasi modal yang besar, utk itu harus mempertimbangkan:

Semua alternatif harus diinvestigasi

Investasi yang terbaik harus bernilai

Sistem yang dikembangkan memerlukan orang yang terdidik

Prinsip Pengembangan Sitem

Prinsip Pengembangan Sitem

(lanjutan)

Tahapan kerja dan tugas-tugas yang harus dilakukan dalam proses pengembangan sistem.

Proses pengembangan sistem tidak harus urut

Jangan takut membatalkan proyek

Dokumentasi harus ada untuk pedoman pengembangan sistem.

Systems Developments Life Cycle

The Phases of SDLC2. Study current

system

3. Define the end-

user’s requirements

4. Select a

feasible solution

5. Design the

new system

7. Construct the

new system

8. Deliver the

new system

9. Maintain and

improve the system

1. Survey project

scope & feasibility

Start

finish

Opinions

6. Acquire com-

puter hardware

and software

1. Survey Project Scope & Feasibility

• Define the scope of the project (include all end-

users)

• Perceived problems and opportunities, business

and technical constraint

• Perceived project goals and possible solutions

A feasibility assessment

(include a preeliminary cost_benefit)

2. Study and Analyze the Current System

To understand the existing system, manual or

computerized

....how the existing system operates

Problem Statement or

an updated feasibility assessment

3. Define End-user’s Requirements

• To find out what they need or want out of the new

system

• To define the inputs, files, processing and outputs

for the new system

A Requirements Statement

4. Select a Feasible Solution

To identify candidate solutions

…how the new system is to be designed, at a very

high level.

Evaluation :• Technical Feasibility

• Operational Feasibility

• Economic Feasibility

Approved system proposal

5. Design the New System

• Justify the time and cost to design the new system

• Design inputs, methods, outputs, files, procedures

• Design by prototyping

Design specifications

6. Acquire Hw/Sw

Specifications of Hw for the equipment and Sw

Configurations

7. Construct the New System

• Programming

• Debugged and Tested

Application

8. Deliver the New System

• Training

• The writing of manuals

9. Maintain and Improve the System

• Evaluation

• Reviews
