To enhance the success of ongoing IT operations, it would be beneficial to apply the following performance evaluation methods - Balanced Scorecard, Key performance indicators – KPI, Earned Value Management – EVM, Service Level Agreements, Six Sigma, Information Technology Infrastructure Library – ITIL. It was not determined that organizational size would influence the relationship between IT evaluation methods and the success of IT operations. The conclusions and recommendations summarize the main concepts of literature analysis as well as the results of the performed research.
