What are the factors responsible for the estimation of system integration test cycle and total integration time?

Answer

The number of system integration test cycle and total integration time are determined by the following parameters:

• Number of modules in the system.
• Relative complexity of the modules.
• Relative complexity of the interface between the modules.
• Number of modules needed to be clustered together in each test cycle.
• Whether the modules to be integrated have been adequately tested before.
• Turnaround time for each test-debug-fix cycle.
