Jim - thanks, a useful framework for managing not only the complexity but also the scale created by the proliferation of systems. This is an increasing challenge for all "Chief Integration Officers”. The multi-sourcing challenge thinking can and indeed should also apply on different levels or layers. Take the delivery layer of increasingly fragmented provision, which needs system control and holistic reporting - as per ServiceGrid - and apply it to the output layer where customers touch the brand. The similar complexity, and scale, of digital eBusiness presentation requires parallel system control and reporting - brand presentation measurement and governance across an enterprise's websites and social media presence (themselves created by the underlying systems!). The model of integrated governance would help foster collaboration between teams to improve digital brand presentation too - Richard
