After completing the test cases, we do:

Export the test cases into Quality Centre.
The test cases will be loaded in the test plan module.
When execution is started. We move the test cases from test plan tab to the test lab module
In test lab, we execute the test cases and put as pass or fail or incomplete. We generate the graph in the test lab for daily report and sent to the specific user.
If we got any defects and raise the defects in the defect module. When raising the defects, attach the defects with the screen shot.   _{Your Comment}
