### Collecting Data Before the Workshop: Measurement and Analysis of Production Indicators
Thanks to this, the process of implementing fresh solutions was more efficient, and employees gained practical experience in new procedures. During the workshop, a temporary goal was also established for the rearranging process, which was 30 min for both analyzed products--A and B. This goal was agreed upon during consultation with the head of the compressor and was intended to determine the real, but at the same time ambitious, standard for the team. After the workshop and the use of new procedures, it was possible to set a time of 25.5 min for the product, which significantly exceeded the assumed goal and confirmed the effectiveness of the changes introduced. In the case of product B, the rearranging time was 35.2 min, which indicates a lack of significant benefits in this case and the need for further improvements in the process. Collecting Data After the Workshop: Measurement of Production Efficiency Indicators After the Implementation of the Changes and the Completion of the Workshop  
In the process of implementing changes based on the improvement workshop, one of the key steps is collecting and analyzing data on production efficiency. The collected information allows for assessing the effectiveness of the introduced modifications and enables further processes. After the workshop, measurements of production efficiency indicators were carried out to assess the impact of the implemented changes on the functioning of machine X. The workshop conducted in the 20 th week, i.e., in mid-May, was an important turning point in the production processes of machine X. Data from May reflect the transitional situation, constituting the point between the results from before the workshop (January-April) and the effects after its completion, visible in the data from June and the following months (Figure 6). Data on the average time of rearranging the product A on machine X is shown in Figure 6, indicating significant changes in the effectiveness of the process before and after conducting the workshop. In the period before the workshop (January-April), clear fluctuations are noticeable, with the longest time in February (34.1 min) and the shortest in March (28.7 min). The average calling time in these months lasts at a level above the target set for 30 min, which indicates problems with the effectiveness of transmitting procedures. In May, when the workshop took place, the rearranging time dropped to 28.1 min before the change, and after the workshop, it reached 27.2 min, which suggests the initial effect of the implemented improvements. After the workshop, in the period from June to September, the rearranging time persisted at a shorter, more stable level, with the lowest value in July (25.8 min). These results show a clear trend of improving efficiency as a result of the implemented changes, consistently reaching the reference times. The agreed goal below is 30 min; they testify to the effectiveness of the workshop in improving production processes (Figure 7). In the case of product B, the data presented in Figure 7 show much fewer benefits resulting from the workshop. Before the workshop, the time of rearranging ranged between 37.4 and 34.6 min. In May, a slight improvement was observed, but this result, which is the average data from before and after the workshop, does not reflect the full influence of the introduced changes. There was no clear improvement after the workshop--in June, the time was 36.6 min, which may have resulted from the initial difficulties in adapting to new procedures. The lack of a stable inheritance trend after the workshop suggests that for product B, the introduced changes could be less effective than in the case of other processes or that there are additional factors affecting the time of transmitting, which require further analysis and improvements.
