# Statistical Process Control Methods

OPSCB/574 Competency 1 Assessment and Rubric
Course Title: Creating Value Through Operations
Competency Assessment Title: Statistical Process Control Methods
Total Number of Points: 100
Assignment Directions
Step 1: Process Evaluation
Create a new Word doc for the elements of this assignment.
Evaluate your process using 1 of the following:
• Use the lean concept to find ways to eliminate waste and improve the process.
• Use SPC or Six Sigma to reduce defects or variances in the process.
Step 2: 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.)
Write your evaluation in your assignment Word doc under the header “Evaluation of Control Chart and Process Metrics.”

Step 3: 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

Recommendations for improvement (weight 15%) | Provided detailed recommendations for improvements. | Provided partial recommendations for improvements. | Provided vague recommendations for improvements or did not provide recommendations for improvements.
The rubric evaluates the following aspects of the assignment:

Evaluation of the process.
Evaluation of the control chart and process metrics using statistical process control methods.
Process evaluation summary.
Summary of the control chart and process metrics based on SPC methods.
Six Sigma, Lean, or other tools evaluation summary.
Description of the Statistical Process Control (SPC) project.
Recommendations for improvement.
Each criterion is assigned a weight, indicating its importance in the overall assessment. The “Mastery” column represents the criteria that demonstrate a thorough understanding and application of the concepts, while the “Meets Expectations” column indicates a satisfactory level of achievement. The “Not Met” column signifies that the criteria were not adequately addressed or not submitted.

Grades can be assigned based on the performance level achieved in each criterion, and the total score can be calculated to determine the overall competency assessment.
