We have used Stakeholder Impact Analysis to support decision making in a case study of an oil
and gas services company that was interested in exploring the feasibility of migrating an enterprise
IT system from an in-house data center to Amazon EC2 [4]. The analysis revealed that the proposed
cloud migration would have many implications for the organization, including non-technical areas
such as the finance and marketing departments. Overall, a positive net benefit was perceived from
the perspectives of the business development functions of the enterprise and the more junior levels
of the IT support functions. A zero net benefit was perceived by the project management and
support management functions of the enterprise and a negative net benefit was perceived by the
technical manager and the support engineer functions of the enterprise. The analysis identified
numerous potential benefits and risks associated with the migration. Most notably, opportunities
for improved cash flow management, opportunities to offer new products/services, and removal of
tedious work were identified as benefits. In contrast, the following notable risks were also elicited:
the deterioration of customer care and service quality; increased dependency on external third
parties and departmental down-sizing.
