a. Assign a monetary value to each of the benefits and costs. If the monetary value is not known, note that.

b. Write additional versions of the problem statement to be sure you have that right.

c. Collect information on all possible options. Try to be as thorough as possible.

d. Nothing. Making a list of costs and benefits is the first step in the process.
