Throw the switch, Igor...
Information has always been at the heart of IT - properly designed IT systems take the core information a business needs and models how they interact with that information, realising some elements in systems that make it happen faster, better, cheaper and without forgetting the 'wetware' bits.
Anything else is either imposition of a process by IT on the business (SAP anyone?) or the politics of the organisation (the NHS NPfIT failed because it did not understand what it was really trying to achieve and failed to control the scope of what it was delivering, a lot of due to the politics of the 'what does it mean for me' crowd).
Shelfware? The over aggressive sale of software to under-informed users desperate for a solution to past mistakes in IT decisions.
Open Source? tends to end up as nice implementations to solve a particular business problem (fragmenting information) or in larger systems that need expensive technical resource to oversee and customise, sorry configure (well we all like to twirl the propeller on out hat every now and then, don't we?)
XaaS? Again it tends to drive more information fragmentation - until someone comes up with a proper solution to orchestrating the flow of information (including service confidence monitoring, security etc.) between the crufty old in-house systems and the bright shiny clouds.
If only people spent more time looking at the arrows between the boxes in the LEAN process flow charts - each one is a 'communications event' with some 'information' passed across it - then they would understand more about what to do with that information and have a reasonable chance of ending up with a solution that worked properly with that information. Instead we rush like 5-year olds to the shiniest software vendors Christmas tree.
And as for the 80% of information the IBM say will be without provenance (i.e. unverifiable in truth or origin), by 2016 or so (that's unverifiable, I can't remember what the presentation said...) let's leave that to the 'Super Hadoopers' to give us some insight that we can test against our own known facts.
Off to get out the Tea (as a) Service and a plate(spin) of Virtual Hobnobs...
