Yes, its possible...and thats called 'Open Innovation'. :-)
SAP attempts to innovate in web 2.0 style. It has tied up 'Innocentive', an Open Innovation marketplace. It connects people from various organizations, academia, talented people across the world who are looking for breakthrough innovation. The platform has so far been used for Pharma, and Retail industries and this is the first time a technology company like SAP has ventured into this paradigm. Am sure there would be tons of IP issues involved in terms of incorporating the open ideas into the product and licensing it out.
But, its a good start. Now, anyone in the world can contribute to the product development at SAP. I have been a subscriber to Innocentive mailing list for quite sometime now. It is interesting to see such a quiet firm suddenly getting the media attention by association with industry leader like SAP. I wouldn't be surprised if more such technology industry leaders join the bandwagon!
