You've been at your current job for a week. Your boss has just filled you in on what you're going to be doing - your job is, according to him, to "improve" the GUI of the current product. He tells you that the person you replaced had been working on it for awhile, but just couldn't seem to get it right. The woman in the cubicle next to yours tells you that the guy quit just before he got fired, and you are the third person hired to make this "improvement". What do you do? (Quitting is not an option - you love the espresso machine). Use your knowledge of software engineering tools and techniques to guide you.
