Assume monetary benefits of an information system of $40,000 the first year and increasing benefits of $10,000 a year for the next five years (year 1 = $50,000, year 2 = $60,000, year 3 = $70,000, year 4 = $80,000, year 5 = $90,000). One-time development costs were $80,000 and recurring costs were $45,000 over the duration of the system’s life. The discount rate for the company was 11 percent. Using a six-year time horizon, calculate the net present value of these costs and benefits. Also calculate the overall return on investment and then present a break-even analysis. At what point does breakeven occur?

Match each activity below to the phase of system development to which it belongs. Before each activity description use one of the following codes:
A — Analysis I — Implementation D — Design F — Follow-up
____ 1. Monitor the system for breakdowns and weaknesses
____ 2. Hire and train personnel
____ 3. Evaluate the efficiency of the system
____ 4. Identify sources of information
____ 5. Select procedures from among alternatives
____ 6. Prepare job descriptions
____ 7. Install processing equipment
____ 8. Corrections in design may be necessary
____ 9. Determine information needs
____ 10. Format reports
a) The requirements of the system provide constraints and performance ranges for the system in terms of inputs and outputs, and its system-wide and technology-related characteristics. The requirements also state the tradeoffs that the stakeholders are willing to make in the development of the system and the constraints and performance ranges associated with testing the system. In defining the design problem how do the necessary concepts come together?
b) From the System Engineering perspective as defined by Kossiakof et al, what criteria should a life cycle meet? And when is a system’s state said to have attained equilibrium and stability?
c) RAS is the main tool that helps to maintain consistency between functional architecture and designs based on those architectures. Briefly discuss using a system of your choice as an example (eg. UAV).
