Slide 3  Analysts tried to build wonderful systems without understanding the organization  The primarily goal is to create value for the organization

Slide 4 Systems analyst adalah orang utama yang menganalisa proses business, mengidentifikasikan kesempatan perbaikan, dan pendesainan sistem informasi untuk menerapkan konsep ini. Merupakan hal yang penting untuk memahami dan mengembangkan melalui melatih skill yang diperlukan untuk mendesain dan mengimplementasikan sistem informasi baru yang sukses

Slide 17 Processes and Deliverables ProcessProduct Planning Analysis Design Implementation Project Plan System Proposal System Specification New System and Maintenance Plan

Slide 18 SYSTEM DEVELOPMENT Methodologies

Slide 19 Pendekatan formal pada rangkaian tahap Menulis code tanpa kejelasan mungkin berhasil untuk program yang kecil, tapi apakah berhasil pada sistem yang besar?

Slide 20 Berpindah secara metodis dari satu langkah ke yang lain Secara umum, sebuah langkah selesai sebelum masuk ke langkah berikutnya

Slide 21

Slide 22 ProsCons Identifies systems requirements long before programming begins Design must be specified on paper before programming begins Long time between system proposal and delivery of new system
