In this example, which is fairly typical of a traditional BI project, the most obvious area of waste is the time spent waiting. Approximately 31 percent of the total project time was time spent waiting for both signoff and resource availability. BI teams also should question the time spent during the detailed design phase. How much of that time is for creating documentation for the developers versus documentation for the customer and/or BI team? They should really question all the steps along the value chain to determine whether they add value and where they can be improved. In the short term, improvement may be achieved via rapid iterations, integrated testing, prototyping, and other agile practices. In the longer term, the implementation of development standards, common processes and procedures, feedback loops and business driven metadata repositories will likely lead to a reduction in waste and greater value.
