 Integrity systems can be thought of as being either predominantly reactive or predominantly preventive, albeit the distinction is somewhat artificial since there is always a need for both reactive elements, e.g., investigations of corrupt actions, and preventive elements, e.g., ethics training and transparency mechanisms. Reactive systems are fundamentally linear. They frame laws and regulation that set out a series of offences, wait for transgressions, investigate, adjudicate and take punitive measures. In many areas, including institutional corruption, resources are limited and, thus, ethically informed decisions have to be made in relation to the prioritization of corrupt activity to be investigated and to what extent. This ethical problem is to be distinguished from the problem of under-resourcing motivated by a desire to hamstring anti-corruption initiatives. Moreover, both problems are to be distinguished from the debate between those who favor increased laws and regulations to combat, for instance, financial corruption, and those who argue for a decrease in such laws and regulations since they unnecessarily increase the cost of doing business.
