Just as Michael Porter's ''five forces'' provided a practical analytic
al tool for describing the forces that shape competitive strategy, so
business ethicists ought to provide business leaders with a workable f
ramework for understanding the sources of ethical obligations. The for
ces that shape competitive strategy vary according to time and industr
y, but are anchored in an ultimate criteria of profitability. Similari
ly, ethics can use a set of analytical categories that identify the re
levant forces to business ethics on the basis of relationality. This p
aper first argues that relationality based on naturalism is the primar
y, plausible value for ethics. Second, it adapts a tripartite dialecti
c from scholars William Frederick and Michael Novak to describe the re
lational categories with which business must contend. Third, it uses t
hese forces in a way similar to Porter's competitive forces to offer a
n analytical language familiar to managers in order to characterize bu
siness ethics.
