The process control method analysis

Different forms of waste occur in our organizations daily, including overproduction, items damaged in transit, inventory, transportation, and overprocessing. Using Six Sigma methods, waste can be gradually reduced by ensuring uniformity in production, ensuring customer preferences are considered, reducing inventory, and streamlining the process. Process mapping programs are used to ensure quality workflow, A process map outlines each step within a process, identifying the task owners and having detailed timelines. They are helpful in communicating processes among the stakeholders and revealing areas of improvement. This helps in reducing wastage while improving quality. (IBM, 2022).

The process of completing a police car computer is the order is placed, the items get sent for production that takes 2 days to go through each step to put the item together this is managed by assembly line and monitored by employees to clear any alarms or issues. Then the production team moves the items to be updated with the internal hard drives and processors specific to the model. This process takes 3-4 days as well. The item then goes to quality to check for any internal issues in the framework, processor, and motherboard. This process lasts for 2 days and then the final quality check is done which also takes place in 2-3 days. As you will see from the control chart below the processing time is below what can be done. In this chart I-MR control chart

The process involves manufacturing car computer systems that take 15 days to process per item on the assembly line. It then goes through 4 quality inspection lines, each taking 2-4 days. Then lastly a final inspection items stay for 2-4 day at each in

The following sample data on the end-to-end processing time for ten items was collected: Item # Processing Time (days)

1-12

2 -13

3 -15

4-11

5 -14

6 -16

7 -10

8 -12

9 -13

10 -14

Calculate the mean (average) processing time:

Mean = (12 + 13 + 15 + 11 + 14 + 16 + 10 + 12 + 13 + 14) / 10 = 12.9 days

(Was told the calculations are incorrect by professor)

Calculate the range (highest value - lowest value) for each sample: Range = 16 - 10 = 6 days

Calculate the average range (R-bar):

R-bar = (6 + 4 + 4 + 5 + 2 + 6 + 6 + 0 + 3 + 2) / 10 = 3.9 days

( Was told the calculations are incorrect by professor)

Plot the points on the control chart with center line at the mean and upper and lower control limits at:

UCL = R-bar * 3 = 3.9 * 3 = 11.7 da ¿s

LCL = Mean - R-bar * 3 = 12.9 - 3.9 * 3 = 8.1 day s

The I-MR control chart is as below. Based on this analysis, the process is variable and out of statistical control. The ideal state would be to reduce the processing time variation and center the process closer to the 5-6-day goal.

Developing a control chart, we first need to identify the important process parameters that help the quality of the items being produced. We collect data like production time in days or hours, end to end manufacturing and complete order time. The process variation is related to different reasons, which are expected or unexpected , Things like machines not working properly, products not passing quality check and possible issues with transportation such as weather or transport breakdowns or accidents. One must understand the data being computed to

use Six Sigma effectively. Six Sigma's goal is to remove variations and bottlenecks, communicate clearly and train team members, be flexible and responsive and to find the problem and focus on it.

Six Sigma was considered for this paper because of its effectiveness in manufacturing, which used a DMAIC method (describe, measure, evaluate, optimize, and control) to ensure effective production levels and qualities the goal is to decrease processing time. “An application of Six Sigma in manufacturing can help an organization reduce pollution, reduce the time cycle of one or more processes, and reduce the cost of production for increasing profits and satisfaction level of its customers.” (SimpliLearn, 2023).

Throughout the process, I collected information on the times the items/products were transferred from the assembly line to the quality control audit stations and then to the customer. After collecting the information, it was reviewed, and the results were that passing the items between quality stations and assembly occurred frequently and caused delays in leaving the facility thus wasting time. After noting the issue, I attempted to solve it by combining responsibilities and testing to ensure applicability in our organization. The process was also passed by a quality assurance official who ensures efficiency in our end productions. Application of lean in various production states ensures customers' needs are considered while wastages are identified and eliminated. Six Sigma also ensures wastage eliminated and optimization of operations, thus streamlining the production process.

Following the evaluation of data, we recognized that the items production period was delayed; other items less in demand exceeded the maximum production period set by the company, while others almost got late all items spent 2-4 days in the second quality inspection. Although the technicality of the items being produced may cause a delay in some processes, through the objective chart, it is possible to determine the length time of an item stays at the additional quality control stations were against the company's objectives. Although there are different charts, each organization should select the best based on one's needs to make analysis and chart information as required. Despite some items meeting the requirements, they are almost missing the deadlines with a few of their products due to the lack of communication between 1S and 2“ quality control stations and the amount of time a item sat at both stations.

Evaluation

There are several ways that the process is going to benefit from the Six Sigma and the DMAIC methods; firstly, the optimization of the production process to reduce time wastage as items are sitting in the quality inspection stations for days. Changes and improvements in responsibilities were made with the approval of the quality assurance officer. The optimization process will reduce the costs of production, saving the company hours of wages, wasted time and possibly being able to pass the savings on to the consumer.

The organization should take advantage of the chart to make continuous improvements to the production process and develop permanent solutions to the delays and increasing costs of production that are passed to customers, making the company uncompetitive.

To collect and analyze the data effectively, the SPC tool was used in controlling the charting process, and the correct time used in completing and shipping a item was accurately

computed for relevant decision-making. SPC data is collected in the form of measurements of a product dimension / feature or process instrumentation readings. The data is then recorded and tracked on various types of control charts, based on the type of data being collected (quality One, n.d.). Throughout the process, the right time recommended by customers to complete their tasks was specified before charting

Improvement recommendation

From the chart, it was noted that customers' deadlines were not met while others exceeded by longer durations, implying lost revenue and customers' confidence in our company. The numerous instances of passing the items from the warehouse to the quality stations were inefficient since we noted several errors. From my recommendation, the items would be inspected immediately and sent to be loaded for pre shipment; then, the quality control team will sign off on items they will be loaded. Reduction in the amount number of time that items are sitting to be inspected will reduce errors and save time and costs incurred by the company.

Conclusion

In conclusion, process improvement is geared toward the improvement of the production process by identifying errors and inconsistencies and then making relevant improvements to ensure the successful delivery of the organization's objectives. The Six Sigma process is a gradual wastage that evaluates the entire production process from the beginning to the end, noting potential errors, delays, and time wastages. The programs check for obsolete and inconsistent or wasteful practices; for example, in our organization, the items which vary from sewing machines to the computers inside of police officer vehicles were getting passed from the manufacturers to

quality control, then to a set of quality control auditors several times, leading to time wasted. If the machines are working correctly then the items would be manufactured correctly as well.

Streamlining the process by ensuring items/products are being inspected once and errors or defects are noted or monitored in real-time item can be removed for further investigation and a new item replaces the defective one before its being shipped will reduce time wasted. It will also ensure that product arrives to its consumer in a timely manner.
