Problem
You work at Your Move, Inc., a large retailer specializing in games of all kinds. The company is in the final stages of developing a new inventory management system, and the IT manager wants you to handle the testing. "Be sure you put lots of errors into the test data," she said. "Users are bound to make mistakes, and we need to design built-in safeguards that will catch the mistakes, and either fix them automatically or alert the user to the problem." Of course, this comment makes a lot of sense, but you've never done this before, and you wonder how to proceed. Should you try to invent every possible data error? How will you know that you've thought of every situation that could occur? Consider the problem, develop an approach, and write up your plan in a brief memo.
