The overall process for developing information systems from planning and analysis through implementation and maintenance
Systems Development Life Cycle
7 phases of the SDLC
Planning Analysis Design Development Testing Implementation Maintenance
Involves analyzing end-user business requirements and refining project goals into defined functions and operations of the intended system
Analysis Phase
Establishes descriptions of the desired features and operations of the system including screen layouts, business rules, process diagrams, pseudo code, and other documentation
Design Phase
Involves taking all of the detailed design documents from the design phase and transforming them into the actual system
Development Phase
Involves bringing all the project pieces together into a special testing environment to eliminate errors and bugs, and verify that the system meets all of the business requirements defined in the analysis phase
Testing Phase
Involves placing the system into production so users can begin to perform actual business operations with it
Implementation Phase
Assess if the entire system meets the design requirements of the users
Alpha Testing
Test the system to ensure it is bug-free
Development Testing
Verify that separate systems can work together passing data back and forth correctly
Integration Testing
Verify that the units or pieces of code function correctly when integrated
System Testing
Determine if the system satisfies the user and business requirements
User Acceptance Testing
Test individual units or pieces of code for a system
Unit Testing
4 Implementations of the systems development life cycle
Parallel
Plunge
Pilot
Phased
Uses both the legacy system and new system until all users verify that the new system functions correctly
Parallel Implementation
Discards the legacy system and immediately migrates all users to the new system
Plunge Implementation
Assigns a small group of people to use the new system until it is verified that it works correctly, then the remaining users migrate to the new system
Pilot Implementation
Installs the new system in phases (for example, by department) until it is verified that it works correctly
Phased Implementation
