Bangladesh has made remarkable achievements over the past decades in developing the healthcare sector despite many hurdles and financial constraints. However, the healthcare sector is gradually falling behind in terms of better service due to inefficiency and medical errors. This study presents how Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) can be systematically used to eradicate inefficiencies and medical errors. The study begins with a brief introduction about the health industry of the Bangladesh and how far it has progressed with the current timeline. Bangladesh has been striving to develop their health industry but high expenditure, medical errors and inequality in service are some of the key obstacles that is hindering the growth of health industry. To overcome the obstacles, Lean Six Sigma DMAIC, a data driven optimization tool, is used. Hospital inefficiency, medical errors, lack of better service, outdated medical instruments and medicine quality require sufficient improvement. The study is done qualitatively as well as quantitatively and the data are collected through questionnaires from 60 patients in Ruma, Chokoria, Chittagong. Lack of better doctors, outdated surgical instruments, medical errors and unsatisfactory health services are focused. The suggested optimization tool tackles these issues through a structured approach in five phases namely, Define, Measure, Analyze, Improve and Control. This allows the health industry to locate the pain points effectively and reduce variation in products or services. Collaboration between the hospital management, doctors, medical equipment manufacturing companies and health service providers is essential in ensuring sustainable growth and continuous improvement.
