Someone posted a question on my Lotus Software Professionals Linkedin group, join it here, it's the largest Lotus group on Linkedin with around 1,400 members.
They had their executives inundated by these quotes from a Microsoft vendor or employee.One would think they would use more modern data but evidently Microsoft can't afford to buy the reports since 2006.
1) Microsoft’s worldwide market share for integrated collaboration environments was 52.6% (+16.8%), while IBM’s was 39.1% (+10.7%). – IDC, July 2006
2) Microsoft's user base grew by slightly more than 17%, while … IBM’s product set has only grown by 11%, leading to a loss of share. IBM’s aggregate share … is projected to be 26%; Microsoft’s share is projected to be 62%. – Gartner, 2006
3) Microsoft continues to gain market momentum and is selling twice as many messaging server seats as IBM. – Forrester, August 2006
I am sure there is more, and I have covered some of this previously here in FudBuster #1.
Let's see the IDC report. If I am looking at the same one while it showed Microsoft leading, it also showed Lotus had a 13% gain in market share in 2006. Unprecedented if the product was truly dying or being put out to pasture don't you think?
IDC issued a report in July 2007 that illustrates Notes/Domino increased its share of the integrated collaborative environments market in 2006 to 40 percent , up from 39 percent in 2005. Outlook/Exchange’s share of the $2.4 billion market slipped to 51 percent from 53 percent over that same period.
As pointed out here IBM is seeing a huge up swell in all things Lotus and has seen the 13 of 14 quarters growth which is really unexpected in a what is considered a flat growth area. More can be found here
Numbers lie, statistics lie even more, but right now Lotus 9(Rnext) and 10(Rnext+) are being worked on and Lotus committed to Disney for the next 5 years of Lotusphere so there is no end in sight, contrary to what Microsoft tells anyone.
