Six Sigma Report: Analyzing Fuel Tank Manufacturing Process and SIPOC

This report presents a Six Sigma analysis of the fuel tank manufacturing process. It begins with an introduction that outlines the need for process analysis and the creation of a SIPOC (Suppliers, Inputs, Process, Outputs, Customers) diagram. The report details the six key steps in the manufacturing process: laser cutting, folding, welding, leak testing, and final inspection. Metrics for evaluating the process, such as responsiveness, accuracy, and cycle time, are identified. Each stage of the manufacturing process is then described in detail, including the specific operations and components involved. The report references several sources and concludes by summarizing the analysis of the production process and the importance of the SIPOC diagram. The report also considers the key stakeholders involved in the manufacturing of buggy tanks.

Introduction
This research paper requires the analysis of the production process according to the
provided data. There is also a need of proposing chart analysis of Supplier Process Outputs
Customers for the process of manufacturing of buggy tank together with key stakeholders and
critical information of the operations of manufacturing.
Building a SIPOC Diagram
During the process of creation of the SIPOC diagram, the team four individuals will
begin by first asking questions concerning the process of process of manufacturing of buggy
tank. The team will then label the procedure with outlines of the most important 6 steps followed
by the documentation of what is delivered and by whom (Model, 2014, p. 187). This
prioritization and brainstorming of critical inputs end the undertakings around SIPOC’s building.
The diagram below shows a chart analysis of Supplier Process Outputs Customers for the
process of manufacturing of buggy tank

The processes that are involved in the manufacturing of buggy tank are explained below.
Step 1: Laser cutting. The steel sheet is first cut at a 2mm thickness for each two fuel tanks on
either side of the chassis. These dimensions are cut from the original steel material before being
taken in the next stage of folding and welding according to the design dimensions below:
Step 2: Folding using the folding machine. The dimensions provided above for the construction
of the fuel tanks are then folded to form the shape of the tanks required. It is not a must that the
tanks should be identical, but their shapes should be the same and the specifications in each
should be similar to proper functionality and incorporations of other components inside the fuel
tanks such as breather ports, fuel outer port, and filler cup (Shakespeare, 2012, p. 175).

Step 3: Tracking and filling corners using manual welding jig. During this stage, the breather
ports, fuel outer pot, and filler cap are welded on the fuel tank (Soleimannejed, 2013, p. 289).
Step 4: Robotic welding station. The robotic welding station is used in welding of other
components in the fuel tanks such as breather pots, fuel outer pot, and filler cup in case of
production of a large number of fuel tanks with similarities in the components and dimensions.
Step 5: Leak testing. This testing is done on the fuel tank after the final completion of both the
tanks to determine if there are any chances of leaking of fuel. This process is done by pouring
samples of fuel on the tanks and determining if there is any leakage in the tank (Model, 2014, p.
178).
Step 6: Final inspection. The final inspection is done through physical testing of the buggy to
determine if the fuel tanks are in a position of functioning properly after being installed in the
buggy (Rasmusson, 2011, p. 182).
Conclusion
This research paper requires the analysis of the production process according to the
provided data. The proposed chart analysis of Supplier Process Outputs Customers for the
process of manufacturing of buggy tank together with key stakeholders and critical information
of the operations of manufacturing have also been discussed in this paper.
