Software projects are notorious for being completed behind schedule and over budget. One primary cause is the inability to accurately define project size, which ultimately leads to unreasonable effort and schedule estimates. Many project managers use software modeling tools, such as SEER-SEM™, COCOMO II, and custom in-house tools for developing estimates; however, the accuracy of project effort and schedule estimates, from any modeling tool, is directly proportional to the accuracy of estimated project size. This presentation discusses the advantages and disadvantages of the Use Case concept as a requirements development tool. And, then presents a process for translating Use Case Points into size metrics, effort months, cost and schedule.
