Don’t you just dread being asked the question, “How long will the modeling take?” I usually react to this question with another question: “How much time are you giving me?” Often however, it comes down to me rolling up my sleeves and coming up with an estimate. I have noticed over the years that my estimates hover somewhere between 20 and 40% of the overall project effort. (Note that the 20% estimate is given rarely – only when the requirements are very well-defined and the modeling and mappings are relatively simple.) What techniques do you use to estimate the modeling portion of your projects?
