might be downstreamDevelopment through “open communities” leads to

potentially broad ideas and creativity

OSS is a source of competition and disruption in marketplaceOffice productivity applications Operating systems (Linux for servers, desktops)Software development environments, …

Community ApproachInternet has changed how enterprises address

technical innovationEnterprises engaging early on with developersShapes IBM technical leaders thinking & approach

to broad collaboration

Enterprise customers are asking for itIncrease choice & flexibilityAdoption/use of open source can reduce time to

market
