SIPOC Chart Analysis 2
INTRODUCTION
This assessment paper analyses the production process of the off-road buggy based on the
provided data by evaluating a supplier-Inputs-Process-Outputs-Customers (SIPOC) Chart
Analysis so as to propose the manufacturing process of buggy tank regarding the key
stakeholders and critical information of the manufacturing operations. A SIPOC Chart Analysis
is a tool used for the purposes of identification of all relevant elements of a process improvement
project before the beginning of the project. It assists in defining a complex project that may not
well scoped and is normally implemented at the measured phase of Six Sigma.
Some of the components required during the manufacturing process of off-road buggy include
fuel outlet port, leak-proof filler cap, breather port, fuel tanks, and filler cap. The fuel system of
the off-road buggy is made of dual fuel tanks on both sides of the chassis. The fuel tank is
composed of a steel sheet of thickness 2mm with baffle plates also made of steel of thickness
1mm. The vent valve acts as a non-return for the fuel system. The baffle plates in the tank reduce
fuel splashing in the fuel tank. On both sides of the vehicle, there is mirror reflection (Badiru,
2009).
SIPOC CHART ANALYSIS
During the process of building the SIPOC Chart, a team of four individuals will start by initially
inquiring concerning the manufacturing process of the two fuel tanks of the off-road buggy. The
team can then brainstorm and prioritize the major processes out of consumers and then identify,
align, arrange, and align the most significant production to the client. The team will then finally
identify the input or information needed to carry out the processes as well as the individual

providing the input. The following are some of the information used during the analysis of
SIPOC for the buggy tank manufacturing process:
Consumers: The consumers are those individuals who will ultimately receive the final output. It
is significant to note that the consumers should receive the product from the manufacturing
company directly and may not basically be the product consumers (George, 2013).
Output: The outputs are the final product distributed which for this instance is the two fuel tanks
of the off-road buggy.
Time estimated: The estimated time is the time taken to fully complete the processes involved
for a particular step.
Supplier: The suppliers are the organizations or individuals who provide the numerous inputs
that will ultimately be used during the off-road buggy tank manufacturing process (Gygi, 2012).
Processes: These are the numerous activities that are normally carried out to satisfy the customer
or consumer requirements who will purchase the final product from the manufacturing company.
The table below shows the chart analysis of the Supplier-Process-Outputs-Customers for the
process of manufacturing of off-road buggy tank:
