An executive uses a software system that calculates the amounts of the federal and state tax incentives and loan guarantees available for energy production of various types. The calculation results are provided to clients on a fee basis. His clients are energy producers in nuclear power, fossil fuel, "clean oil," renewable electricity, and related undertakings. The software system has become slow, resulting in missed due dates for reports that clients were counting on. The executive decided to form an integrated project team (IPT) to determine the root cause of the problem.
