Project selection methods in six sigma and a case study

Six Sigma methodology states a management using measurable data instead of instincts. The basis in Six Sigma is to improve the processes and reduce the errors to zero. To achieve this, it is necessary to use the sources effectively in Six Sigma projects, particularly time and costs. The waste of the sources decreases and the Six Sigma methodology is accepted by spreading over all the companies thanks to a rightly chosen Six Sigma project. The theoretic part of the study consists of two elements. In the first part, the Six Sigma?s basic concepts and statistical techniques are defined and in the second part, some project choosing techniques are defined. In the implementation part of the study, defined project choosing techniques are implemented in a hospital. Firstly, the hospital?s critical quality characteristics are defined. To evaluate the present conditions of the hospital, a face to face questionnaire study was held with a group of 400 people. The questionnaire was prepared according to the 5 point likert scale. DPMO was founded by considering the unsatisfied patients number as the error number and main process short termed sigma level was calculated. Short termed sigma level?s appearing under 3 denoted that things were not going alright. Critical sub-processes were defined and the projects thought to be implemented in these sub-processes were defined. The project which was going to make the company raise its optimum profit were defined by using project choosing techniques and the projects thought to be implemented in these sub-processes were defined. By this way, sources were not waste and the company managed to achieve its goals with the rise of the customer satisfaction.
