What are the assumptions of the execution-time component model?
The execution-time component is based on the several assumptions:
(1) Tests show the environment in which the program will be used.
(2) All failures are experiential.
(3) Failure intervals are s-independent of each other.
(4) Hazard rate is a similar that changes at each fault correction.
(5) The failure rate is proportional to the s-expected value of the number of faults remaining.
