Key Success Factors for Green IT Projects
Economic Tradeoffs
Lack of
Implementation
Barriers
Stakeholder Support
Having the support of key stakeholders is
critical to the success of any project but,
particularly for Green IT initiatives as they
require education and a shift in attitude
A lack of choice due to missed refresh cycles,
inadequate funding, misalignment with
physical facilities, lack of resources, such as
IT staff, can all be barriers
Organizations should be willing to invest
funds in IT projects and take up strong
initiatives driven towards adoption of green
practices through healthy investments
