Gartner's Magic Quadrant is an industry leading report for a whole mess of business assessment information. In their own words:
Gartner Magic Quadrant research methodology provides a graphical competitive positioning of four types of technology providers in fast-growing markets: Leaders, Visionaries, Niche Players and Challengers. As companion research, Gartner Critical Capabilities notes provide deeper insight into the capability and suitability of providers' IT products and services based on specific or customized use cases.
In his summary of the fallacy of the report he points out some glaring issues.
1. Their report is not timely and does not take into account recent acquisitions and changes to the company.
2. BlackBerry just acquired WatchDox which Gartner called "'visionary’ in [their] most-recent MQ for Enterprise File Sync and Share (EFSS)".
He goes on to challenege the validity of their methodolgy altogether.
The EMM MQ criteria is also no longer able to keep up with the enhancements that vendors like BlackBerry are making. Instead, it’s weighted towards MDM features that have long been commoditized, and fails to consider cutting-edge services that address EMM needs now and in the future.
