The idea is to break up these projects in phases and into small projects rather than go with a Big bang approach. Create small POCs, demonstrate small success stories. The best way to show proof of success of typical process Automation or other IT Innovation drives is to get the Business users to see and measure success-the best way is to implement a POC, develop a small self service portal, where they are able to key in specific data and see tangible benefits.
Unless the Business Users do not perceive this as an Experiment and a Risk, the project will not meet its objectives. If this is achieved, not only the Roll Outs of the project is guaranteed but also in the least time and well within the reduced Budgets. The CIO must make these success stories visible to his Organization at the right times during the project progress.
