•  Planning, installation, and testing could demand more time than originally anticipated. 

•  Forrester did not evaluate the cost and benefits associated with any next generation 

equipment. However interviewees are considering the future cost of next generation 
upgrades to their equipment, and they are concerned that the acquisition costs of next 
generation equipment may exceed their benefits.  

The following risk specific to Cisco’s Unified Wireless Network was considered in this study: 

•  End-user productivity gains may vary from originally anticipated estimates due to the 

specific characteristics of an organization’s wireless deployment and usage prior to 
migration.  

The following tables show the values used to adjust for uncertainty in cost and benefit estimates. 
Based on the comments from the interviewed customer, we applied risk to the benefit categories to 
adjust for any uncertainty but did not apply any risk to the cost categories. Forrester uses list prices 
for all software licensing, maintenance fees, and hardware costs. The professional services costs 
typically pose the greatest uncertainty, and in this case, they were very minimal.
