This question considers the ramifications of a considerable change to the requirements on the design of the software. The first change is that the customer now wants a web-based user interface instead of one that is PC-based. Determine the changes that need to be made to the requirements to have a different type of user interface, with different issues in the possible configurations (multiple operating system versions on the PC, multiple browsers, and multiple versions of HTML and Java). What changes, if any, need to be made to the software development life cycle model or the design process?
