If morality in business ethics is primarily about shared values, then business discussion, which can take many modes of communication with various parties, takes a central place in moral business-decision making. In many cases, more than one party may often be involved, and we should include others in our decision-making processes.
Discussion is important in moral business-decision making, as it is often important that others around us agree with or understand our decisions. For example, the consumer products industry often collects feedback through surveys and marketing gigs to take the business discussion forward.
We can learn from discussing moral questions with others. Others can provide valuable insight or experience. For example, the software makers can have valuable feedback from users. That is why they beta test their products before launching a product.
There is no formula for making good medical diagnoses, or for giving good legal advice. All of these involve significant elements of experience and sensitivity.
Experience and sensitivity will not guarantee that a good decision is made, but they help assure that decisions are not hasty, or lacking in sufficient consideration of ranges of problems.
