A tool based framework for applying Six Sigma methodology to services and transactional data

Service organisations need excellent service levels for achieving customer satisfaction as well as value creation and growth. However, providing high service levels and maintaining quality standards is more difficult and significantly different in service organisations. Several service organisations are realising that Six Sigma methodology is the next logical step in achieving superior customer service. However, not all Six Sigma tools can be used to improve service operations. Moreover, tools applicable to service and transactions may need significant modifications before they can improve these operations. In this study, we report how Six Sigma methodology can be utilised in service organisations. For this, we first propose the use of select-define-measure-analyse-improve-control methodology. Second, we study and analyse Six Sigma tools to identify ones relevant for the services industry. Third, we provide suggestions on how some of the identified tools can be modified and applied to services and transactions.
