Many respected researchers believe the method holds promise, including the members on our panel, although with careful qualifications. On the other hand, COTS software manufacturers tend to view the method with skepticism for several reasons. One problem is the difficulty in verifying that injected faults are representative of real world faults. Another is that SFI may not be as efficient in identifying errors in software as more conventional testing. The three panelists explored wide-ranging alternatives to the industry view.
