Years ago I worked on a large effort to reengineer a distribution
center for a large retailer. We provided an estimate for both the business analysis work and for the entire project, which would involve the organization’s first use of Electronic Data Interchange (EDI), new business processes, many software changes, and the purchase of new barcode scanners. The business analysis effort took far longer than we anticipated, and at the end of it we refined our estimate for the total project. When we reported the new estimate to the president of the company, he literally pounded his fist on the table and asked, “How did we get to this point? Why didn’t we know sooner? You’ve already spent all this time on the project and what do we have to show for it? Nothing!. Absolutely nothing!”
