You said "Shadow IT arises when lines of business and consumer demands in speed are not met." -- Perhaps there's more to this phenomenon than obtaining digital business solutions at the desired speed of the LoB leaders. I recall that Salesforce.com was a pioneer in designing a superior software UI, when compared to the awful typical user experience of a legacy CRM platform. My point: CIOs that attempt to deliver poorly designed apps at greater speed will surely fail. The savvy eagle-eye is focused more on the desired outcome.
