Think about problems at two different stages of product development. Fix Problems Early to Save MoneyĪs you move along the product development process it becomes more expensive to fix problems. Find the cause of your problems, and then address the cause rather than attempting a quick fix that may or may not work long-term. Those that worked on the tower kept trying to compensate for the lean, but because that didn’t address the cause of the lean, the problem kept returning. Quite often when faced with a bad outcome in a design, it is tempting to just change something that will fix the outcome rather than understand the root cause of the problem and ensure that a solution addresses the cause of the problem. There are three main lessons I learned from the Tower of Pisa: first, find the root cause of problems in your design second, the cost to correct problems in a design gets more expensive as the further along it is in the product development process and third, sometimes designs are better when they are imperfect. Even the flagpole on top of the tower has been made vertical, rather than following the angle of the rest of the tower. Instead of addressing the root cause of the lean, efforts were made to compensate for the lean in the third, fifth, and eighth stories. Even as the tower’s second story was being completed the tower was starting to lean. As the structure got heavier the soil beneath the tower began to settle unevenly. The soil beneath the tower is composed of mud, sand, and clay, water tables in the area are also fairly high. The lean of the tower is due to the soil beneath the tower not being stable enough to support the tower.
