As a prospective Google Software Developer, you need to look at things from a broader perspective to gain a bigger picture of what your internal customer (department) or external customer (client) wants. In the early stages of the software development cycle, you may find that a feasibility study might be required. There are two important factors to consider before determining whether or not a feasibility study is required. A feasibility study is broken down into two essential categories. The first is Technical in nature, and the second is an Operational view. The Google interviewer wants to know if you follow protocol by offering a feasibility study to the client or go through the motions of your job. It's important to mention this in your interview because it helps crystallize in the interviewer's mind that you go above and beyond the norm to get the job done right. Again, the interviewer is asking for your opinion, so it's important to express your opinion to explain why you think it should or shouldn't be performed.
