This assignment has a grading rubric, attached.

To learn how to apply SPCM to a process, continue the flowchart from Week 1 and identify variances within a process. You can find variances from the data identified in Week 1.

Complete the Week 2 Statistical Process Control Methods Worksheet, attached.

To begin, measure the entire process over 10-12 periods of time (days, months, years). Use time as your Metric.

Create a control chart including the baseline, upper control limits (UCL) and lower control limits (LCL). 

NOTE: Feel free to use estimated time when real data is unavailable. 

Submit your assignment using the Week 2 Statistical Process Control Methods Worksheet.

You may include your computations and graphs on the work sheet or attach them separately.

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

<Write your evaluation here>

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.)

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

? Identify any out of control conditions. Four tests are performed. Use the legend to identify the points corresponding to a particular test.
? If a test looks for a proportion of points, only the offending point will be identified. For example, if eight points in a row are on one side of the centerline only the eighth point will be identified.

Week 1 – Professor’s Feedback

This assignment is designed to cause you to demonstrate your understanding of a process, and how you can “see” the process using a Flowchart Diagram,

Additionally, this assignment causes you to analyze your process as a process observer, using metrics and measurements to determine how the process can be improved.


A FLOWCHART is a graphical way to describe the process. It uses boxes to depict resources, arrows to depict flows.


You have done an excellent job describing an “as-is” process.


The steps in the process are as detailed as possible. Note the example found in text, Table 3.1


Refer to text, chapter 2.2 Process Metrics:




Used appropriate symbols for your flow chart to analyze the process and make decisions.

Refer to Announcement titled Week 1 Process Flowcharts.


You have inserted NOT metrics as required. Metrics are used to measure the effectiveness of the process flow. 


The first step (measure the process) is critical for the second (improve the process)—if you do not know how to measure a process, then it is difficult to know how to improve it (or even to know if you have improved it) (Text. P. 26).


Your metric is clear. You have NOT shown the data.


NOTE: Feel free to use estimated date when real data is unavailable.


You have created a second “To-be” flow chart.


After analysis of the current (as-is) process you discover where you can make improvements to the process by analyzing metrics. The 2nd flowchart reflects the improved process based on your analysis of where in the process can be improved.

Process Improvement Flowchart

A process metric is a quantitative indicator of a process’s efficiency and effectiveness. For every observer or creator of a process, the three most important indicators are inventory, flow rate, and flow time (Cachon & Terwiesch, 2020, Chapter 2, pg. 29 – 30). The current process at Hendrick Health involves scheduling an appointment, insurance verification, pre-registration, and registration. An analysis of the current and future flowchart will be evaluated.

As Is Process Flowchart

Process Overview

The current process at Hendrick Health involves scheduling an appointment, insurance verification, pre-registration, and registration. The current process is causing delays and inefficiencies in Hendrick Health’s revenue cycle. In order to improve the process, process improvement techniques are needed to reduce errors, streamline the process, and improve overall customer satisfaction (Antony et al., 2019).

Process Evaluation and Improvement

Metrics to measure the current process include the average time it takes a patient to complete the process, the number of errors in patient data, and the number of patients that abandon the process. Process improvement techniques can be used to reduce errors, streamline the process, and improve overall customer satisfaction (Vermaelen & Kovach, 2021). To improve the process, the scheduling process should be made more efficient with automated appointment reminders. The insurance verification process should be automated with a system that can quickly and accurately verify insurance information. The pre-registration process should be updated to allow patients to complete the process online and provide pre-filled information to reduce errors (Vermaelen & Kovach, 2021). The registration process should also be automated, with a system that can quickly and accurately verify patient information to reduce waiting times.

Process of Future State.

The improved process flowchart would look like the diagram below. The future process will be more efficient and reduce errors, leading to fewer delays and improved customer satisfaction. The
