Tying ROI proposals to Unique Strategic Value
Page's example speaks about Hershey and tying the savings back to increases in charitable donations. For a company with a Green strategy, the savings could be translated into cars off the road, homes powered, or trees saved. For a restaurant, this might be tying the savings to profit from N restaurants, for a REIT, this might be tying the savings back to the profit from N commercial buildings.
Any way you look at it, as ROI proposals become required, its important to not only quantify unique value, but to begin to differentiate your proposals with a core connection to the organization.
