14、 is a product and can be manufactured using the same technologies used for other engineering artifacts. 2 Customers, end-users, practitioners, project managers and sales people are all considered as players in the software process. 3 A good software is flexible, so it can easily accommodate changes
15、brought up with the requirement change. 4 We should consider the implementation view first during software requirements analysis. 5 Every computer-based system can be modeled as an information transform using an input-processing-output template. 6 Test cases should be designed long before testing be
16、gins. 7 Recovery testing is a system test that forces the software to fail in a variety of ways and verifies that software is able to continue execution without interruption. 8 Adding more people to a project that is already behind schedule is a good way to catch up. 9 Change cannot be easily accomm
