I won't even try to interpret Ariba's earning announcement and the street's reaction (which at first was first negative and later positive). Fellow blogger and Open Source procurement geek Dave Stephens attempted an analysis earlier in the week. In my view, the transition haze from a license model to a subscription one completely obfuscates any attempt to get at what's actually going on in Sunnyvale. But I'm certain of at least two things. First, the sky is not falling for Ariba, inc. (nasdaq: ARBA). Second, their business is not on fire. The truth is obviously somewhere in between.
