A new "Policy Management Scorboard" (based on "direct feedback from service providers, market share data, and publicly available financial data") by Shira Levine [pictured], directing analyst for service enablement and subscriber intelligence, Infonetics Research ranks the 8 largest global vendors of policy management solutions: Alcatel-Lucent, Amdocs, Ericsson, Huawei, Openet, Oracle, Juniper, and Redknee.
"Huawei’s and Ericsson’s strong financials and market share [see "[Infonetics]: Huawei Leads the $1B Policy Management Market" - here] growth, along with solid scores in the service provider feedback categories, propelled them to the top of the list .. However, we believe that Oracle and Amdocs have the potential to provide a real challenge to the leaders if and when they’re able to work through some of their post-acquisition issues, and Alcatel-Lucent will likely move up the list once its financials are sorted out.”.
In Infonetics' 2013 and 2012 reports, Openet led the market (here and here).
