Optimization of production processes is a key field for companies that wish to remain competitive on the increasingly global market, therefore it cannot and should not be avoided. Lean production offers different methods of dealing with problems related to process optimization. My thesis covers different lean methods, while some selected ones are used in the example of lighting equipment production.
Based on a case study by means of value stream mapping and MTM time determination method, it presents a model for efficiency evaluation of production process optimization that can be applied by the company to decide whether to proceed with the introduction of changes or not. The model is based on calculation of time savings compared with the required investment.
During the case experiment, the value stream mapping method was recognized as an efficient method to define wastes in processes, since often we can clearly define losses only after visualizing and recording a process in detail. The MTM method was recognized as an extremely useful time determination method for processes that are not running in production yet, since it can be used to select from different solutions and to predict saving possibilities based only on the analysis.
The use of lean methods has an influence on key performance indicators and therefore on the financial success of the company. It can also help establish employee friendly work environment, from the point of view of creativity as well as efficiency.
