10. SDLC Process
• Terdiri atas 4 fase
• Tiap fase terdiri atas beberapa langkah
• Tiap fase terdokumentasi
• Tiap fase dapat dieksekusi secara sequentially,
incrementally, iteratively atau dalam pola lain.

11. Questions to be Answered
• Planning phase
– Why should we build this system?
– What value does it provide?
– How long will it take to build?
• Analysis phase
– Who will use it?
– What should the system do for us?
– Where & when will it be used?
• Design phase
– How should we build it?

12. SDLC: Fase Planning
1. Project Initiation
– Develop/receive a system request
– Conduct a feasibility analysis
• Technical feasibility
• Economic feasibility
• Organizational feasibility
2. Project Management
– Develop the work plan
– Staff the project
– Monitor & control the project

– Model the current system
– Formulate the new system
2. Gather the requirements
– Develop a system concept
– Create a business model to represent:
• Business data
• Business processes
3. Develop a system proposal

14. SDLC: Fase Design
1. Develop a design strategy
2. Design architecture and interfaces
3. Develop databases and file specifications
4. Develop the program design to specify:
– What programs to write
– What each program will do
