As a systems engineer, you are required to do a trade study on common coffeemakers available in market. Conduct product research and narrow down your choices to five products. Please conduct the following steps:

i. Develop a top - level function list for a common coffeemaker, limiting yourself to no more than 12 functions; ii. Draw an FBD of the coffeemaker using the functions in

(i); iii. Convert the coffeemaker FBD to an IDEF0 diagram and a UML activity diagram respectively;

iv. Identify exactly four selection criteria, not including purchase price or operating cost;

v. Assign weights to each criterion, explaining in one sentence your rationale;

vi. Construct a utility function for each criterion — describe it verbally or graphically; vii. Research the actual values for your criteria for each alternative; viii. Perform the analysis, calculating a weighted sum for each alternative;

ix. Calculate the effectiveness/unit cost for each alternative using purchase price for cost; and

x. Describe your choice for purchase, along with any rationale.
