Under what circumstances would it be best to use each of the following frameworks: the philosophical ...

The traditional philosophical approaches - consequentialism, deontology, and virtue ethics  are time-honored approaches that have been refined into the modified 5-question; the modified moral standards; and the modified Pastin approaches for convenient decision making in those instances noted below. The philosophical approaches, taken as a set, can be applied to any problem rather than a specific sub-set, and they would be superior where there are strong expectations for the demonstration of duty and of virtues in the solution.
Given what was said in response to the last question, the modified 5-question approach seems best suited to short-term, profit-oriented problems that confront the law and impact the environment or require a tailored, specific fifth question. The modified moral standards approach is suited to people-related or future-oriented problems where externalities are present that are not captured in the profit measure. Modified Pastin's approach suits problems internal to an organization. Each approach/or part thereof can be used on almost all problems.
