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 pro- cess for making these modifications that will ensure that the requirements document and the system implementation do not become inconsistent.

The Agile model

Explanation:

We can point out that this is all about the software development lifecycle model. In the software developmental lifecycle, the agile model is the most suited model that can be used to bring changes as per the requirement.

It is the model that provides huge flexibility as the changes can be made to the software even if the application is running. Moreover, this model follows documentation regarding the process of bringing the changes to the software. And even the new changes should pass the quality assurance test in order to go to the production phase.

What this does is that it actually ensures that your application is fit and is consistent to handle and perform operations.
