Thestrategy, whereas the second half of our sample began cloud roles that execute the processes, the tool functions and theprojects without having defined their target state and cloud associated information are all based upon the process design.road map. This finding is supported by the results of the“scale of implementation” question, where 50 percent of proj-ects today cover a pilot scope. Only 20 percent are targeted atenterprisewide cloud deployment.
