Business has a consistently poor experience of the internal IT function. It is now all too easy for the business to bypass the central IT function. There is a business shift to cloud service providers offering infrastructure-less solutions with no perceived IT involvement. Outsourcing and the divestment of IT functions in response to business wishes to remove the overhead. The business need to respond to the interrelated developments of digital, mobile and social computing and perceived inability of the central IT function to respond.
If the IT function cannot react to the requirements of the business due to business pressures, the business will go elsewhere. Shadow IT - the acquisition of IT solutions outside the control of the IT function - is an unpleasant and common reality. 50% of IT expenditure is routinely spent outside the control of the IT function. Shadow IT is a symptom of a post-IT world.
The central IT function loses relevance and control. Businesses reduce their reliance on the core IT function.
IT architecture should act as a glue joining the business strategy to the IT strategy. IT architecture needs to operate as an internal business consulting And advisory function. An effective business oriented IT architecture function can get the correct balance between too little and too much, too slowly and too quickly. The IT Architecture team needs to operate as a team rather than a set of siloed internally focussed IT roles, involving business as well as technologists.
