As an ethic that spans science, engineering, business, and the humanities, transparency is operating in such a way that it is easy for others to see what actions are performed. Transparency implies openness, communication, and accountability.
Transparency is practiced in companies, organizations, administrations, and communities. For example, in a business relation, fees are clarified at the outset by a transparent agent, so there are no surprises later. This is opposed to keeping this information hidden which is "non-transparent". A practical example of transparency is also when a cashier makes changes after a point of sale; they offer a transaction record of the items purchased (e.g., a receipt) as well as counting out the customer's change.
