### Collecting Data Before the Workshop: Measurement and Analysis of Production Indicators
Analysis of the number of machine X beats per minute for the product A show significant improvement in the process after the workshop. In the period before the workshop (January-April), the results shown in Figure 8 show some fluctuations. The lowest value was recorded in February (16.74), and the highest in March (18.11). This range of values suggests a lack of stability in the production process, although in May, the number of strokes increased to 18.27, which could be the result of the initial optimization activities conducted during the workshop. After the workshop, the results show a clear and lasting increase in efficiency. Already in May, there was a further increase in the number of strokes (18.50), and this trend persisted in the following months. In June, the number of strokes increased to 18.70 and reached the maximum value in July (18.85). In August (18.78) and September (18.67), the result remained at a prominent level, which confirms the effectiveness of the changes introduced. Stabilization of the results at a higher level after the workshop suggests that the improvements used--such as improving the processing procedures or optimization of machine settings--had a positive impact on the production process. Regular results in the range of 18.67-18.85 beats per minute prove that the efficiency of product A significantly increased, and the process has become more repetitive. For product B (Figure 9) the number of the machine's beats per minute before the workshop was more stable, with a slight increase to 17.55 in May. After the workshop, the data were more variable. In June, the result dropped to 17.01, which may indicate difficulties in the initial stage of implementing changes. In the following months, the values fluctuated, reaching 16.88 in September. A lack of permanent improvement in the case of product B may result from the more complex requirements of this product, which have not been fully included in the workshop. An additional indicator that illustrates the efficiency of machine X is the number of beats per minute (Figure 10), measured for the entire machine regardless of the product. These data allow for assessing the overall equipment efficiency before and after the workshop. In the period before the workshop (January-April), the number of machine X strokes increased gradually, from 16.43 in January to 17.29 in April. The result from May, equal to 17.60, represents transient values, reflecting the average results before and after the workshop. After the workshop, from June to November, the number of machine strokes showed a tendency to further increase, despite slight fluctuations. In November, it reached the highest value in the analyzed period of 17.93. Figure 8: Comparison of the number of machine X for product A before and after the workshop. Before the workshop, the availability of production time (Figure 11 and Table 2) increased from 74.6% in January to 79.9% in May. After the workshop, the availability of production time continued to increase, reaching 81.4% in September. This is an improvement of 8% compared to January and 1.9% compared to May. A decrease in the share of time intended for reference--from 8.75% in May to 8.0% in September--also indicates the effectiveness of the workshop. The downtime rate, which before the workshop decreased from 13.0% in January to 11.35% in May, showed fluctuations after the workshop but generally decreased to 10.6% in September. This indicates a gradual improvement in the stability of the process. The collected data after the workshop confirms the effectiveness of the actions carried out, especially in the case of product A, where a permanent improvement in the time of the conversion and the number of machine beats per minute has been achieved. A clear shortening of the conversion time and an increase in the availability of production time indicate the effectiveness of the workshop. However, the results for product B indicate the necessity for further improvements to better adapt the processes to the specifics of this product.
