The Brief

You are working with a manufacturer who receive and order a number of raw materials which are then used in production or for general maintenance.

Currently there is no procurement system in place and no way for the companies to validate which suppliers are providing us with quality goods and which are not.

There is also no consistency between different plants and the vendors we are purchasing from.

The programme management team have identified the need to centralise and understand supplier quality as a priority.

There has been a major effort in recent weeks to consolidate the data.

The team have now managed to gather data from across the plants with information around the material, defect and vendor.

They have also managed to get the number of defected materials and also provided a value for the minutes of downtime caused by the defected material.

The management team are now looking for some help to visualise and extrapolate the findings from this data.

Enterprise Manufacturers Ltd are slowly adopting Power Bi within their organisation as such one of the analysts has made an effort at starting to model the data.

Given the importance of the project and urgency management have decided to enlist the experts to get this over the line.

Some key questions the business want answering are;

Which vendors/plants are causing the greatest defect quantity?

Which vendors/plants are causing the greatest downtime?

Is there a particular combination of material and vendor that perform poorly?

Is there a particular combination of Vendor and plant that performs poorly?

How does the same vendor and material perform across different plants?

The business are hoping that you can help answer these questions and maybe even provide some insights that they may have overlooked.

UPDATE Re @alexbadiu question around purchase amounts

At the moment this data is not available as the business are struggling to get the data out of the system.

It has been agreed that if the management team see value in this first iteration of Power BI development they would be willing to invest in the technical expertise required to extract the purchasing quantity.

The management team are happy to accept in this first instance they wont be able to see percentage of defects compare to purchased amount.

@haroonali1000, I have a question regarding the Total Defect Qty. In the dataset provided we do not have information regarding the quantity of materials received. We only have the Total Defect Qty and Total Downtime Minutes.
Do we receive the exact same quantity for each material, from each vendor & plant?

Hi
is my first challenge.
I downloaded the raw data file and was looking at the tables.

Please correct me if I am wrong, but look like the facts table “Supplier Quality” for the Vendor, Category and the other attributes has already the values-description instead of the IDs.

Should when I bring the tables into Power BI, convert all attributes in the facts table into the corresponding IDs, so then can links the table and use the description for the analysis.

Thanks
Luca

Hi @LucaB72. That’s generally the first step I do to more easily understand the data model; using merge queries to ensure only the IDs are in the fact table, if possible. This also has the benefit of ensuring only the facts are in your fact table(s) while the descriptions are in your dimension (or lookup) tables.

Hi,
in the file, if I am no wrong, in the fact table “Supplier Quality” we do have alaready the dimension descritions, instead of the IDs.

If I lookup (linkthe tables fact with the dimensions) will be by the descriptions and when using the dimensions from the dimension table will have only the IDs

Or I am missing something.

I attached two snapshop from the data as I see for the

7

from the few databse set I workd with, the dimension tables were linked to the facts with numeric lookup columns and then I used the dimension description from the dimension table for the pivoting/analysis

@LucaB72,

Just by glancing at the data, I’m in agreeance that really the only data that is needed is the “Supplier Quality” data. There are some other things you can do with the other data, but I would think you could do everything you need from this one tab of data.

Thanks

Hi @haroonali1000,

You might want to include that in the brief as an update so everyone knows when they are reading it. Related to the inventory purchased and struggling getting that information

Hi @haroonali1000,

great challenge, looking forward to creating my first viz.
I have a question about plants, is there further information about location? are all plants located in the US?

Hi
just one point, on the tables provided, we have been given number of Defects in terms of Quantity and Downtown minutes, as absolute value.
No reference to overall quantity delivered and production time.

may be a defect quantity that in absolute quantity look high compared to the delivered amount is in percentage small and maybe within the acceptable tollerance.

However for this challenge, as stated due to the senior management start getting interested in the analytic side and use of Power BI will proceed with the defect quantity and downtime time as provided, and put as reccomandation to collect also delivered quantity and time for processing to have a more meanfull analysis.

HI
when I plot the “Lant Location” and a map, the values for “Venice” and “Reading” it show me in Europe (Italy and UK, instead of USA Florida and Pensilvania)
Is there any way to force them to the correct geographical location without modifing the raw data supplied?

I attached the screen capture of the map viz

Thanks

Hi @LucaB72. Shouldn’t be a problem … just add a new column for “Country” to your [Plants] table, set it to “US” and then add this to the map. Without latitude and longitude Bing maps tries its best but can easily give the wrong answer when place names are not unique (e.g., Venice, CA and Venice, Italy). Hope this helps. Greg

To add to @Greg’s comment, you may want to add “State” as well. There are several States that have “Venice” as a city.

First timer on the challenge. I have been trying to make sense of the defects number, is there a base to compare the number of defects?
