Your company is developing the software for a telephone switching system for a single client. This very large system is delivered to the customer in phased releases. The customer occasionally observes system failures, such as loss of availability, loss of specific services, or erroneous services. There are two testing phases at which it is possible to gather additional failure data internally: integration testing and system testing. An attempt must be made to fix all failures, whether observed by the user or in test. Devise the necessary forms for a data-collection scheme that has to take account of the following: a. There are rigid reliability requirements for the system. b. There are wide variations in the ability to fix failures occurring in certain parts of the system (one of the project manager's major concerns). c. Your change control procedure has to be auditable.
