The study was conducted at the organisation Mercado Medic AB, whohad problems regarding production planning in one of their assemblysections. The assembly section that was studied produces componentsthat are later to be used in the assembly of medically customizedchairs. The study examines both how work is conducted in thesection, and how orders are communicated to and within said section.Data was collected by observing the assembly section, and byinterviewing both the personnel and planning manager. Cycle-timeswere also measured for the activities that are carried out withinthe section. The data was then analysed with theories originatingfrom the sphere of quality management and Toyota Production Systems.The analysis shows that the current state of communications to, andwithin the section, is vertical. Orders are communicated frommanagement top – down, thus having the section produce componentswithout an actual need from downstream sections. This way ofproducing is more commonly known as a "push-system".The study presents, based on the analysis, a future state for howthe use of a kanban system and a simplified and balanced workflowwould solve the problem currently had with production planning. Thisway of producing is more commonly known as a "pull-system". Thefuture state is recommended to be implemented by the personnel inthe form of "experiments" (PDSA/PDCA-cycles), thus allowing thepersonnel to learn more about their process while experimenting.Lastly, it is important to note that the future state that thisstudy presents is not necessarily the best state that can be. Oncethe future state presented in this study is achieved, a new andimproved future state should be made. It is the endeavour ofstriving towards a continuously evolving future state that ensurescontinuous improvements.
