A very timely article from Zeus Kerravala of Yankee Group, "UC Vendors Must Step Up Interoperability" (link to TechTarget). It's a nice independent validation of the strategy IBM believes is right for not only our clients, but is critical for the continued growth of the unified communications marketplace. A few key quotes:
IBM has been among the more collaborative UC vendors, as well. In fact, the value proposition of its Sametime Unified Telephony (SUT) is built around multivendor solutions. IBM has also been very aggressive in pushing its Unified Communications and Collaboration (UC2) offering into its developer and user community as evidence of the big UC move it made with its annual Lotusphere conference.
The same cannot be said for the two mindshare leaders, Cisco and Microsoft.
You can get a look at more details on how IBM supports a robust developer community in the Lotus domain of IBM developerWorks, and a robust Lotus channel in IBM PartnerWorld. With over 400 Business Partners (and growing) who integrate with Sametime, we can proudly point to our leadership in moving integration and interoperability forward for unified communications.
