Abstract A CBA helps you consider whether to give a green light to a project and to invest funds and energies in bringing it to fruition. CBAs are in wide general uses today, primarily in the business world, where the focus is generally on making good financial decisions. Changing your mind-set to a Benefit-Cost Analysis (BCA) invites you to look first at the benefits, and then look at whether and how you can manage the costs. BCAs are equally applicable for addressing personal, family and social projects.
