2021: Week 52 Departmental December Operations

 Created by: Carl Allchin

One of the constant tasks I have had in my career is dealing with complaints data to ensure the customers / clients of the organisations get a better experience than previously. The final challenge for 2021 is helping our Prep Air team improve by understanding their customers' complaints. 

Input

One Excel workbook. Two worksheets:

1. Complaints


2. Department Responsible

Requirements

  • Input the spreadsheet
  • Count the number of complaints per customer
  • Join the 'Department Responsible' data set to allocate the complaints to the correct department
  • Create a comma-separated field for all the keywords found in the complaint for each department (help)
  • For any complaint that isn't classified, class the department as 'unknown' and the complaint cause as 'other'
  • Output the file

Output


5 data fields

  • Complaint
  • Department
  • Complaint causes
  • Name 
  • Complaints per person
13 rows (14 incl. headers)

You can download the full outputs here. 

After you finish the challenge make sure to fill in the participation tracker, then share your solution on Twitter using #PreppinData and tagging @Datajedininja, @JennyMartinDS14 & @TomProwse1

You can also post your solution on the Tableau Forum where we have a Preppin' Data community page. Post your solutions and ask questions if you need any help!

Free isn't always a good thing. In data, Free text is the example to state when proving that statements correct. However, lots of benefit can be gained from understanding data that has been entered in Free Text fields. What do we mean by Free Text? Free Text is the string based data that comes from allowing people to type answers in to systems and forms. The resulting data is normally stored within one column, with one answer per cell. As Free Text means the answer could be anything, this is what you get - absolutely anything. From expletives to slang, the words you will find in the data may be a challenge to interpret but the text is the closest way to collect the voice of your customer / employee. The Free Text field is likely to contain long, rambling sentences that can simply be analysed. If you count these fields, you are likely to have one of each entry each. Therefore, simply counting the entries will not provide anything meaningful to your analysis. The value is in
