Formally, we use an internally-defined variation of the the VEE Model, but in practise we usually informally extend it to the Dual Vee model. This process takes a little getting used to (you need to balance the benfits from how deep you want to define things). ...and as for requirements - they are key. Learn and live by the IEEE 1288 standards for requirment verbiage - doing so has several benefits: it protects you from scope changes, it makes sure that the customer knows what they're going to get, and it's a standard that is common in military, aerospace, medical, etc industries, and if you're used to using it then you'll have a competitve advantage. Take a look at this.
