2. Some Information Systems Management Information Systems 2 How to develop information systems?

3. Systems Development Life Cycle The systems development life cycle (SDLC) is a structured step-by-step approach for developing information systems. Management Information Systems 3 The Waterfall Methodology

4. SDLC Management Information Systems 4 1 Planning 1 Planning 2 Analysis 3 Design 3 Design 4 Development 5 Testing 5 Testing 6 Implementation 6 Implementation 7 Maintenance 7 Maintenance SDLC Systems development goes through a cycle Once completed, a systems moves into an ongoing maintenance phase that parallels the initial development process---planning

5. Phase 1: Planning Management Information Systems 5 1 Planning 1 Planning 2 Analysis 3 Design 3 Design 4 Development 5 Testing 5 Testing 6 Implementation 6 Implementation 7 Maintenance 7 Maintenance SDLC 1.Define the system to be developed 2.Set the project scope 3.Develop the project plan

6. Phase 2: Analysis Management Information Systems 6 1 Planning 1 Planning 2 Analysis 3 Design 3 Design 4 Development 5 Testing 5 Testing 6 Implementation 6 Implementation 7 Maintenance 7 Maintenance SDLC 1.Gather the business requirements 2.Prioritize the requirements
