Q1.Prepare a fishbone diagram to address the question “Why is our business declining”? Use at least the 4 categories of materials, process/methods, people, and machines to structure your fishbone diagram.

FISHBONE DIAGRAM:

Materials Process / Methods

Raw material of low quality. No implementation of kaizen (continuous improvement)
Bad distributor relationships. Long production time
Delayed supply of raw material SOP’s not met properly
Inventory shortage No business process reengineering according to competition

Lack of communication Limited Competitive analysis Slow production No training and Development Low production capacity Limited skills and Knowledge Out of date machinery Less technological advancement People machines

Q2. Create a SIPOC diagram for the order-taking portion of the pizza order process. Assume your business is struggling with poor customer satisfaction and is specifically examining all interactions with customers to find areas for improvements.

Q4. Create a histogram using the following purchase order data:

What is the shape of the variation in the histogram? Where is the variation centered? How spread out is the variation? Are there any outliers in the data?

Assignment Solution Case Solution

• The shape of the variation in the histogram shown above is that the shape is in a complete bell shaped curve which means that the data is normal; hence less variation occurs in the data. Similarly the histogram can said to be normal.

• Secondly, from the range 1000 to 1200 the variation is centered which means that the data is similar between these ranges.Moreover the frequency for this centered variation is 4, which means that the variation can said to be centered at this point.
• The variation is limitedly spread out because the bars are firstly increasing and then coming to a decrease which means that the data is not quite spread out.
• There are no outliers in the data as the curve is said to be normal. Outliers prevail in those histograms where the curve is up and down but here the curve is in a complete bell shaped curve, hence it can be said that there are no outliers or if there are any they are in a very small amount which can be omitted.....................
