2023: Week 51 - Elf Toy Production

Challenge by: Jenny Martin

We're getting festive for the penultimate Preppin' of the year! And more than that, we're collabing with Workout Wednesday! So once you complete this challenge head on over to Workout Wednesday to build a fun dashboard with the data.

Santa has noticed his elves, while enthusiastic, are not always the most predictable when it comes to toy making. He sets quotas for toys at the start of the year but the way the elves track their toy building doesn't make it easy for Santa to tell if they'll have enough toys for Christmas deliveries. So he's looking to get prepared for next year and get the Elves' Toy Building Tracker connected to a Tableau Dashboard so they can see where to focus their enthusiasm. 

The only problem is that their tracker, whilst festively themed, will need a little reshaping before it's optimal to work with in Tableau Desktop. It may or may not be based on an Excel file I encountered in the real world this year!

Inputs

The Toy Building Tracker, in all its festive glory:

An Elf Name Lookup table

Requirements

  • Input the data
  • Extract the information for which toys belong to which list (hint)
  • Update the Quota to represent the number of toys needed
    • e.g. Barbie's dream house Quota should be 40% of 200M
  • Match the Elves' Initials to their Names
    • e.g. CA = Blinky Sparkles
  • It's the Production Manager who is responsible for the number of toys produced so we only need to keep information about them, so Santa knows who to share the dashboard with
  • Reshape the data so we have a Date field
    • Make sure the data type matches
  • For the first output, Santa wants to find out in which week certain toys exceed their Quota. You'll need to create a Running Sum of Toys Produced, as well as a field highlighting whether a toy is Over or Under Quota
  • For the second output, wants to see some top level figures for the year. How will the Quotas need to be adjusted for the Over/Under Production?
    • Aggregate the data to the Toy level of detail
    • Calculate how much each Toy is Over or Under its Quota
    • Check at the list level whether there are enough Toys for the Number of Children on that list
    • So that Santa doesn't take too many Toys on his sleigh, the Toys with the most overproduction for each list should be the ones translated into spares (if there are more toys than children on the list)
    • Output the data

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! 

Then head on over to Workout Wednesday to build a fun dashboard with the data.

Created by: Carl Allchin Welcome to a New Year of Preppin' Data challenges. For anyone new to the challenges then let us give you an overview how the weekly challenge works.  Each Wednesday the Preppin' crew (Jenny, myself or a guest contributor) drop a data set(s) that requires some reshaping and/or cleaning to get it ready for analysis.  You can use any tool or language you want to do the reshaping (we build the challenges in Tableau Prep but love seeing different tools being learnt / tried). Share your solution on LinkedIn, Twitter/X, GitHub or the Tableau Forums Fill out our tracker so you can monitor your progress and involvement The following Tuesday we will post a written solution in Tableau Prep (thanks Tom) and a video walkthrough too (thanks Jenny) As with each January for the last few years, we'll set a number of challenges aimed at beginners. This is a great way to learn a number of fundamental data preparation skills or a chance to learn a new tool — New Year...

 Created by: Carl Allchin Welcome to a New Year of Preppin' Data. These are weekly exercises to help you learn and develop data preparation skills. We publish the challenges on a Wednesday and share a solution the following Tuesday. You can take the challenges whenever you want and we love to see your solutions. With data preparation, there is never just one way to complete the tasks so sharing your solutions will help others learn too. Share on Twitter, LinkedIn, the Tableau Forums or wherever you want to too. Tag Jenny Martin, Tom Prowse or myself or just use the #PreppinData to share your solutions.  The challenges are designed for learning Tableau Prep but we have a broad community who complete the challenges in R, Python, SQL, DBT, EasyMorph and many other tools. We love seeing people learn new tools so feel free to use whatever tools you want to complete the challenges.  A New Year means we start afresh so January's challenges will be focused on beginners. We will u...

How to...Handle Free Text

Image
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 ...
