304 Part IV: Controlling Your Software Project Say you have 100 project issues in your issues database. Pareto s rule says that 80 of them are the result of 20 of the causes. The Pareto chart enables you to easily see what types of issues are causing most of the problems on your project. Some typical causes of problems in a software project include Inadequate software testing Vendor noncompliance Improper end-user training Lack of defined scope User error Technical issues Technology becoming obsolete Keep in mind that every project is different and the problem causes we list here may not be typical of every project. These are just examples for instructional purposes. Also keep in mind that even though we use the Pareto chart for looking at the causes in system testing, training, and implementation, you can use Pareto charts as a metric in other areas of your software project. Table 15-2 shows a list of issues, causes, and ranks for a software implementation in which physicians and nurses enter their patients medication and laboratory orders into a medical software system. These problems and causes are related to the testing phase of the project, but you can use the Pareto chart to review the causes of problems in other areas of your project.
