As part of our shift to cloud and open source platforms, we chose to introduce a number of culture changes. Early in the process, we decided to make the cloud migration a rallying cry for the technology organization. Specifically, we challenged senior technology staff regarding the fundamentals of what our systems did and how well they served the business. This resulted in key changes in the way we addressed the fundamentals of our multi-petabyte, big data problem. In this process, new high-potential technology leaders were identified and elevated in the organization. The hiring and staffing effort that accompanied this effort also provided an opportunity to further reshape the technology profile of the company.
