System Development Life Cycle

Internal testing is to make sure that the computer code is efficient, standardised, and well documented.
             1.4.5 Integration and System Testing: Brings all the pieces together into a special testing environment, then checks for errors, bugs and interoperability.
             1.4.6 Operation and maintenance: The system is set up in a "real" environment and operated. Errors that have gone undetected are corrected.

             1.5.1 System Analysis: Define what constitutes a solution to the problem.
             1.5.2 System Design: identify in detail how the system will be constructed.
             1.5.3 System Development: Maintain System.
             1.5.4 System Implementation: Write the program & procedures; Install & test system.
             1.5.5 System Operation: Make sure the system work well.

             1.6.1 System Analysis: Define what constitutes a solution to the problem.
             1.6.2 System Design: identify in detail how the system will be constructed.
             1.6.3 System Implementation: Write the program & procedures; Install & test system.

             1.7.1 Problem Definition: Establish what the problem is.
             1.7.2 Analysis: Define what constitutes a solution to the problem.
             1.7.3 Design: identify in detail how the system will be constructed.
             1.7.4 Implementation: Write the program & procedures; Install & test system.
             1.7.5 Validation: Make the new system work without problem.
             1.7.6 Evaluation: How does the user think about the new system.

             1.8.1 Recognize Problem: Establish what the problem is.
             1.8.2 Define User Requirements: Define what constitutes a solution to the problem.
             1.8.3 Analyse Existing System: Check which system has been owned.
             1.8.4 Design New System: identify in detail how the new system will be constructed.
             1.8.5 Build New System.
             1.8.6 Install System .
             1.8.7 Operate and Maintain System: Provide support & enhancements.
