Statistical Process Control Methods
Process Evaluation
Evaluate your process using 1 of the following:
· Use the lean concept to find ways to eliminate waste and improve the process
· SPC or Six Sigma to reduce defects or variances in the process
|
Doing a quick evaluation on the Document Review Process from week 1 using the Six Sigma process evaluation I did notice some defects. For one the purpose of this review process is to get a document from author to the fleet. Yet while the process does accomplish that it does that a little too slow meaning that there too many steps and a lot of holes in the process. |
Evaluation of Control Chart and Process Metrics
Complete the following in Excel:
· Calculate the defined process metrics including variation and process capability.
· Develop and display a control chart for the process.
Evaluate the control chart and process metrics using Statistical Process Control (SPC) methods. Determine whether the process could benefit from the use of Six Sigma, Lean, or other tools. (Include all calculation and charts.)

After seeing the metrics, it is noticeable that there are more times that we would have wanted to admit that we are not delivering documents on time. It is also noticeable that at times even when we do meet the required deadlines, we are just meeting those by a day or two. That shows that there is so much need for improvement. |
Executive Summary
Write a 700-word executive summary that includes the following:
· A summary of the Process Evaluation (using either Lean or SPC or Six Sigma)
· A summary of the Evaluation of Control Chart and Process metrics based on SPC methods
· A summary of your evaluation of whether the process would benefit from the use of Six Sigma, Lean, or other tools
· A description of the SPC project and recommendations for improvements

Executive Summary Six Sigma While there were a few options to use to evaluate processes, I choose to use the Six Sigma process evaluation. The Six Sigma DMAIC process (define, measure, analyze, improve, control) is an improvement system used to improve processes or products at Six Sigma quality levels. The reason I chose this evaluation process over others is because the Six Sigma is very detailed from start to finish. This is a document review process that needs to get fixed. The customer pays for documents to be delivered with all software and those documents must be perfect. For that to happen each document that is written by an engineer must go through the document review process to make sure it is perfect. For now, I measured all the key aspects to the current process is time and no errors. Some of the data that I collected was the time it took from when the engineer passed on the document to the technical writer to the time it was signed. I also collected some data on how many times the document went back and forth from the author to the technical writer. Once we had all the data, we analyzed the data and seen that the document goes back and forth too much which was very time consuming. So, once I knew where the problem was, we went ahead and tried to improve it by combining some aspects of it. Once that was done was, we have seen how it was working and it did make sense. To make sure that this process continues this way I went ahead and added a Quality Assurance person to monitor every step. Evaluation of Control Chart Looking at all the data it is noticeable that documents are not being produced on the appropriate time. Some documents are way over the threshold and others are almost late in delivery. While there may be a few reasons as to why some documents are late and others are not the point is that the chart was able to show us how many documents are not meeting the requirements and how many documents are almost not meeting the requirements either. So, even though we are meeting requirements we are cutting it very close to not delivering on time. Evaluation This process would benefit from the Six Sigma DMAIC process and honestly any other tool for process improvements. The reason is that any process improvement will find a problem in a process if there is one. With this process and just because of things always changing there were a few holes that needed to be fixed to be able to get the customer what they were paying for. Recommendations for Improvement The SPC tool that was used was control chart were all the data that we gathered was inputted. We put how long it took to get a document finalized and signed. We also made sure to include the time frame that the customer gave us for all these documents. We noticed of course that at times we did not meet the requirements of the customer regarding time frames. And at times we also saw how documents were delivered and they were not perfect meaning there were a few noticeable mistakes that were done. Based on the evaluations that I did and the data that was presented the first thing that was decided on was that the documents would only be sent out once through email for review. Once everyone had the chance to review the document give or take 1 week or 2 (because of multiple document reviews, travel, time off) a meeting would be set to go over all the comments collected and overall everyone approve the final draft of the document in real time. This would dramatically cut the time and it will also reduce the mistakes made since the documents will not be going back in forth or emails will not get lost. Conclusion Process improvement tools are set to make our day to day life easier. While at one point of time all we had to do was write a few processes and procedures we never took into consideration that at times these processes and procedures are outdated and might need to be changed. These tools are here to help us see what we are not seeing anymore. References MoreSteam.
