The requirement that enterprise software vendors deliver a measurable return on investment (ROI) has never been greater than right now. Customers are demanding that ROI analysis be a critical factor in their decisions to acquire new enterprise software. Without a demonstrable return, few customers are willing to invest scarce capital and human resources in new enterprirse software. A more complete analysis of return can be had by looking at the overall payback that enterprise software can offer to a company. Enterprise software payback includes not only quantifiable improvements in bottom and top line functionality, but also more qualitative measures-—such as new business opportunities, improved customer and partner relations, and improved time to market—-that contribute significantly to the success of a company's enterprise software implementation and use.
