Scott W. Ambler. Beyond Enterprise Data Modeling - Bringing data professionals and application developers together. When project teams work under the assumption that they can do anything that they want, that they can use any technology that they want, chaos typically results. Functionality and information will be duplicated and reuse will occur sporadically if at all. Systems will not integrate well. Systems will conflict with one another and cause each other to fail. Costs will skyrocket because similar products from different vendors, or even simply different versions of the same product, will be purchased and then operated within production. Although each individual project may be very successful, as a portfolio they may have serious challenges. It doesn%u2019t have to be this way.
