-> Analysis
    @ Conduct preliminary investigation
    @ Perform detailed analysis activities;
        * Study current system
        * Determine user requirements
        * Determine solution
-> Design
    @ Acquire hardware and software, if necessary
    @ Develop details of system

-> Implementation
    @ Develop programs, if necessary
    @ Install and test new system
    @ Train users
    @ Convert to new system

-> Operation, Support, and Security
