Developing clear business cases for our system is fundamental to driving adoption of the Auto-ID Center's technology. Insights already gleaned from the work of this subgroup inform many aspects of our work, such as target costs for hardware. But the main focus of this research is to create a set of tools and research papers that, taken together, plot a migration path that takes users and vendors to a world where, in five to ten years, adoption is commonplace. This work must enable businesses to make sensible strategic investment decisions at each step along this path. The work complements the work of the Business Case Action Group, which aims to show how companies might save or make money from specific uses of our technology.
