Softside Systems has a $100,000 fixed price contract for installation of a new application system. The project is expected to take 5 weeks and cost$50,000. Experience with similar projects suggests a 0.30 likelihood that the project will encounter problems that could delay it by as much as 3 weeks

List and review the principles of risk management.
One requirement of a power-generating system states that it must provide 500 kwh minimum output. The system has three powergenerating subsystems, X, Y, and Z. Constraints on physical size indicate that the output capacity of the overall system will be split among the three subsystems in the
