Rework Process: Determining the Current State of the Rework Process and Developing a New Process that Enables Transparent Rework at GE Healthcare Umeå
Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
One of GE Healthcare’s goals 2014 was to reduce the amount of rework with 10 %. When the company initiated the work towards this goal, they suspected that the registered data of the amount of rework did not comply with the actual amount of rework. They believed that in order to reduce the amount of rework, they first had to ensure that gathered data complied with the reality. That is where this thesis project enters. The purpose of this project is to define the current state of the rework process in the whole factory and to determine the definition of rework. It is also to develop and create a requirements specification and a concept for a new rework process that makes the amount of rework transparent for the organization.Interviews, observations and surveys were conducted at the company in order to map the current state of the rework process. The gathered data was analyzed and resulted in a requirement specification, which became the foundation of the following concept development. Two focus groups with employees at the site were conducted in order to intercept ideas and requests of a future rework process and registration system of rework. Three concepts were developed and then compared against each other in a selection analysis. One concept was chosen for further improvement work and validation. Finally, a recommendation was formed to the company.The mapping of the current state revealed that the current process is inconsistent and complex. The system for registration of non-conformances, called NCR, is complicated and troublesome to use. The process needs to be standardized and the NCR needs to be simplified. The developed concept contains both a standardized process and a simplified NCR. The concept also eliminates a non-value adding activity which means that the NCRs will be processed quicker. Finally does the new concept implicate that the creator of each NCR will receive feedback of the taken approach as a result of the NCR.
