2024: Week 26 - SuperBytes Customer Complaints Part 2

 Challenge by: Tobias Colmer

We're continuing with DS43's challenges so over to Tobias to explain his next challenge. 

_____________________________________

After recovering from last week's data breach that targeted our Superbytes complaint data, more discrepancies within the data were discovered, such as complaints that took over 100 days to resolve being considered as timely. We need to fix this.

Input

The input for this challenge is the output from last week.

Requirements

  • Input the data
  • For Customer Complaints that are still In Progress, set the Date Resolved to today's date (for the output below this is set to 26th June 2024)
  • Create a Days to Resolve field for Complaints which are closed
  • Create a Days Open field for Complaints which are In Progress
  • Update the Timely Response field to correctly say whether it was Timely or Not, based on if the Date Resolved was less than 14 days
