Economic values are often an important determinant.

Ethical values have to be considered as well.

Risk management is another consideration.

Explanation:

Economic values are often an important determinant. This value requires analysis of how a decision will impact the various stakeholders financially.

Ethical values have to be considered as well. This involves considering what actions or outcomes would be considered to be morally acceptable or unacceptable. This is often a very difficult thing to analyze, as it's entirely subjective, and some future consequences that might change individual's minds may be difficult to foresee.

Risk management is another consideration. Some individuals or societies are more accepting of risk than others. The probability of a bad outcome from a given decision needs to be calculated, so the decision can be evaluated.
