Develop and evaluate a trade study to purchase a new smartphone (use real product alternatives that you find online). Please be sure to document enough so that I can tell what you've done.

1. Build a consequence table.

Include at least three alternatives and at least three attributes (the attributes cannot all be identical to the tablet example from the week 3 slides, but you may use 1 or 2 of those attributes).

Fill in the values in the consequence table using real data and/or constructing ordinal attribute scales.

Ensure that none of the alternatives are dominated by another. If they are, adjust your alternatives or attributes.

Do not include the exact attributes that we used in the tablet example at the end of class.

2. Develop a multi-attribute value model. You may assume an additive value function for this exercise.

Use mid-value splitting to assess the value function for each individual attribute (5 point minimum). Fit a smooth or piece-wise function to the points.

Choose weights (c1, c2, c3). Since we only covered developing weights for two attributes, you do not need to use a formal method, but at least provide an explanation/justification for your weights based on the relative values of the attributes. (e.g., the differences in price were small so I gave price low weight, I am willing to pay a lot to gain performance, etc.)

3. Use your value functions to evaluate the alternatives and make a selection.

4. Choose a single parameter (e.g., the relative importance/c-value of an attribute, or the price of an alternative) and perform a one-way sensitivity analysis over that attribute. Present a chart showing this sensitivity analysis and explain in words what it means for the decision.
