One of the principal claims made to support various government projects is that they will offer a positive return on investment (RoI). From one perspective, levels of RoI are scrutinised as part of the cost/benefit analysis and consultation process on major projects and form part of the ‘business case’ for such projects (presumably the term ‘business case’ is used to distinguish such discussion from non-financial issues involved in any project). The same is true when subsidies are given.
