Main Description
The Delivery Team must refer the Maintenance Change Request Analysis And Design Change Document to understand the
coding requirements. In this activity, either a new code is developed, or the existing code is modified as per the
maintenance change request requirements. Delivery Team must make the required changes in the code (or create a new code).
Coding must be done as per the defined coding standards. Developed code must be reviewed to ensure that the source code is
defect free and is in line with the requirements. Unit test cases are created, and unit testing is performed on the
reviewed source code where the individual units or components of the application are tested to verify that each unit or
component operates as designed. This helps the developers to modify the source code immediately without affecting the
functioning of other units or programs. Code reviews and unit testing must be conducted and defects must be logged. This
helps in reducing the defects leaked into production. Appropriate review and test records must be maintained and tracked to
closure before proceeding with next steps.
Once the review and testing defects are closed, the Delivery Team must perform the build. List of major functionalities
along with the known errors and issues must be submitted to the testing team. The created build must be reviewed,
baselined, labeled and copied to the necessary environment for validation testing.
