Collaboration has always been a part of business models in one form or another, but today more than ever organisations are working together to achieve a common end where they may not otherwise connect. Communications technologies have certainly helped but recent trends in social networking, portal and web-based process automation technologies have combined to define a new era for collaboration. Enterprise 2.0 is unlikely to ever resemble a ubiquitous, open Lotus Notes but there are huge opportunities for real-time efficiency gains where like-minded entities can share business requirements in collaboration platforms. Perhaps the public sector (Government 2.0) has the best opportunity to do this where agencies already share owners, compliance frameworks, and even outcomes sought. Centres of excellence can lead the way as hero agencies hardening new solutions that scale and accommodate their peers. Technology vendors need to also embrace this trend with new, even integrated, models that enable entities to share costs and risks as well as gains. This is the hero sum game.
