Part A:
Solution I)
This assessment is on the measuring of the length of the bearing house box whose dimension
is 100*80*60 mm. All concerned five batches dwell with the 10 boxes each. The measurements
are mentioned below:

Table 1
Measurement of boxes Length
In the above mentioned table the columns are represented as D1S1, D1S2, D1S3 .... Etc. this
are there to represent the day one and student one respectively. From the above mentioned table
it can be seen that variation is very high but this variations are inner the specification limit, so we
must create Shewhart control chart (Salic and Zelic 2018). Control chart, which was discovered
by Walter Shewhart in the year 1920. The discovery of control chart became very useful for
mainly two reasons, they are common cause and chance cause (Salic and Zelic 2018). The

common cause is seen as within acceptable limit while on the other hand the chance cause is
advised to analyze the process and control in terms of customer specification. This analysis also
helps to identify the credibility of the process to meet the requirement of the customer. The
calculation of Shewhart control chart is given below:
