In most cases the overall prioritization of business and IT change requests and the steps involved in the decision making process are not transparent enough for all stakeholders. Therefore it is essential that the business change request management process is visible and understandable in order to make the right decisions which are acceptable for all stakeholders. For this reason the prioritization and selection process should be built in an effective and efficient way by using quantitative tools, for example, by following Six Sigma methodology. This article will explain how we manage the prioritization and decision making process.enText/Conference Paper1617-5468
