When emergency changes have to be made to systems, the system software may have to be modified before changes to the requirements have been approved. Suggest a model of a process for making these modifications that will ensure that the requirements document and the system implementation do not become inconsistent.
Even before a change to the specifications has been approved, emergency system adjustments may need modifying the system software. Describe how to make these changes such that the requirements paper and the system implementation are not at odds.
How might you use a model of a system that already exist? Explain why it is not always necessary for such a system model to be complete and correct. Would the same be true if you were developing a model of a new system? Who should be involved in a requirements review? Draw a process model showing how a requirement review might be organized.
