You have included some excellent information about lean and the use of control charts. This assignment requires you to choose a specific process and evaluate it. Within the evaluation should be a discussion of how lean would apply to the specific process. Identification of a key metric to measure the process. Observation of the process. Development of a control chart. Analysis of the control chart, and finally how the process can specifically be improved. A video for how to create a control chart has been posted in Collaborate and a sample Excel sheet creating a control chart has been posted in the Course Questions area.

Process Evaluation
According to Morgan & Sobek II (2021), the lean process is a set of management
techniques that improve efficiency and eliminate waste. The lean process works by reducing and
eliminating non-value-adding activities. According to Womack and Jones, the lean process entails
five key principles; flow, value stream, pull, and perfection (Womack & Jones, 1997). When
evaluating the process, it is better to use the lean process as it ensures better management, increases
productivity, increases efficiency, and improves teams’ morale. The benefits the lean process
brings to the project are manifold as it improves overall business performance and reduces waste.
Implementing the lean technique will realize immense benefits as the process will be more
effective and faster, thereby increasing productivity. Additionally, there will be a reduction in
process inefficiencies and wastes, thereby boosting the process’s overall performance.
Executive Summary
One of the major goals of any company is to obtain maximum efficiency. According to Li
et al. (2017), maximum corporate efficiency is obtained when maximum productivity is at a
minimum cost. Additionally, organizations derive optimality from reducing waste and producing
efficiently. The lean concept will come in handy to analyze the customer check-in process. The
lean process refers to a set of management tools that reduce waste and improve efficiency.
Ordinarily, the customer check-in process could be prone to numerous shortcomings and
challenges, leading to wastage of time and resources. Thereby, the lean process could be adopted to
increase efficiency and reduce wastage of resources.
The implementation of the lean technique in the process could take place sequentially in 5
steps;
Isom 3
Step 1: Specify a value
This stage aims to determine the benefit the process intends to have to the final consumer. In the
check-in process, the value will be assessed based on the benefit derived and the ability to meet
customer needs at a specific time and price.
Step 2: Map
This stage entails determining the value stream. Through this process, categorization of the current
state is made and eliminated.
Step 3: Flow
This stage entails making the remaining steps on the value stream flow, eliminating barriers, and
coming up with products that significantly improve the lead time.
Step 4: Pull
This process entails letting customers respond to the changes as needed without creating forecasts.
Step 5: Perfection
At this stage, the changes are assumed to have already been implemented, and the process should
already be receiving rewards. However, this process is cyclical and entails a consistent update to
ensure optimum benefits are realized at each point in time.
In the Evaluation of Control, Chart SPC has predominantly been used to determine the
problems of the process. SPC charts play a crucial role in controlling limits and a centerline. SPC
Charts analyze process execution by plotting information points, control limits, and a centerline.
Finally, a process should be monitored to assess the method’s capabilities. Before evaluating
process capabilities, common cause changes must demonstrate the common ground of change. It is
Isom 4
critical to have a significant preparation capability that is not affected by exceptions and variations
caused by a shaky handle. There are seven primary phases that we must follow while gathering and
producing vital information about the chart and how it might aid the process of checking in
suppliers. The seven steps include (Hessing, n.d.).;

The measurement method,

Differentiating the processes,

Concurrently performing the gage R&R,

Determining quantifiable qualities of the method,

Collecting data and plotting the SPC chart,

Creating a subgroup technique and examining plans,

Describing natural variation of properties, and

Checking the variation method.
The process would significantly benefit from using other techniques such as six sigma and
the lean process. The primary goal of the process is to improve the company’s performance. I
believe that the six sigma and the lean process would be applied. The six-sigma approach provides
organizational tools crucial to improving business performance (Kwak & Anbari, 2006). Through
the six-sigma, performance is improved and a decline in product variation; thereby, the process
leads to a reduction in defects, increased profitability, increased efficiency, and improved morale
of the employees. On the other hand, the lean approach aims to increase the efficiency of a
company and reduce wastage. Additionally, the SPC technique could be adopted to control a
process or a production process. Through control, the process can monitor process behaviors and
find solutions to production issues.
Isom 5
The project proposed uses SPC and lean processes to improve customer experience. The two
monitoring and evaluation approaches are applied to a customer check-in process. The major aim
of these tools is to help come up with solutions that will help deal with various process issues.
Through the cyclical lean approach, continuous improvements are made to ensure that benefits are
derived at each point in time. On the other hand, the SPC technique aims at controlling the
production process through the adoption of statistical techniques. The approach ensures behaviors
are monitored and thereby finding solutions to production issues. I recommend that the company
adopt modern technologies to facilitate easier communication with customers through calls or
emails. Additionally, I also propose using automated systems that will help reduce the long time
taken on queue to be served and thereby increase productivity.
