Considering the financial framework constructed above, the results of the costs, benefits, risk, and 
flexibility sections using the representative numbers can be used to determine a return on 
investment, net present value, and payback period.  

Table 18 and 19 present the risk-adjusted values after applying the risk-adjusted method indicated 
in the Risk section. 

It is important to note that values used throughout the TEI Framework are based on in-depth 
interviews with four organizations and the resulting composite organization built by Forrester. 
Forrester makes no assumptions as to the potential return that other organizations will receive 
within their own environment. Forrester strongly advises that readers use their own estimates within 
the framework provided in this study to determine the expected financial impact of migrating to 
Unified Wireless Network.
