4. Rate each choice for each criteria
Evaluate your different choices against the criteria. While using the same rating system (in our case, from 1 through 5), rate each criteria individually. For example, if you think your mobile app has tremendous business value, give it a 5. (Keep in mind: The values for each choice don't need to be different. Equal weighting is perfectly acceptable.)
For each of these values, you have to make sure that higher values represent more preferable options. For example, a high ROI should lead to a high Business Value score because a great ROI is beneficial to your business. On the other side, for instance, high development costs should result in a low Costs Value because high costs are negative.
