SUPPLIER, INPUTS, PROCESS, OUTPUTS, AND CUSTOMERS (SIPOC) DIAGRAM
Introduction
The study aims to devise a SIPOC diagram for an off-road buggy. This diagram has
analysed the process of production as per the information provided in the case study. The SIPOC
chart has considered the critical information which are in the best interest of the key stakeholders
and manufacturers. The given model has been identified with the problem of non-identical fuel
tanks which are present on the either side of the buggy. Moreover, the fuel system is normally
depicted with off shelf fuel pump and plumbing. However, the scope of the SIPOC is depicted
with fabrication of the fuel tanks only. The present diagram suggests all the relevant process
which are required for the interaction between tier 1 suppliers and also transformation of the
operation at the end user. This is done by including the relevant discussions pertaining to
Suppliers, inputs, process outputs and customers.

Suppliers
The main supplier of the off-road buggy has been discerned in terms of The Job Shop
Inputs
 Fuel Tank- It needs to be discerned that the off-road buggy comprises of the two fuel tanks
one on either side of chassis. These are further discerned with steel sheet with 2mm thick. The
fuel tank is seen to include the filler cap, a fuel outlet port and a breather port. In addition to
this, the fuel tank is seen to be fitted with a leak filler cap.

SUPPLIER, INPUTS, PROCESS, OUTPUTS, AND CUSTOMERS (SIPOC) DIAGRAM
 Chassis
 Vent Pipe
 Leak-proof filler cap- 1 tank per 2.5 min
 Baffle Plates
 Laser cutter- 1 Laser cutter (42mm/sec cut, 30 sec load and 30 sec unload)
 Folding machine- 1 Folding machine (1 fold per 15 sec)
Process
 Cutting using the Laser Tool- Total Process time of 3 minutes
 Folding- Total Process time of 1 minute
 Tacking and filling corners- Total Process time of 3 minutes
 Identifying and eliminating the waste in production-
 Leak Testing- 1 tank per 2.5 min
 Rework with grinder and manual welder- Total Process time of 5 minutes
 Final inspection- 1 min per part
Output
 Increased sales volume by 20%- The process optimisation will be able to increase the overall
volume by 20%
 Identical mirror reflection of each other in fuel tanks- To correct the present problem of not
identical mirror reflection
 Increasing the buddy sets per week- Following production rate of 10 buggy sets per week

Customer
 Quality- Improved quality will be evident in form of more flexibility in terms of fabrication of
the fuel tanks
 Speed
 Better Design- The improved design will be evident with identical fuel tanks
