2021: Week 19 Prep Air Project Details

 Challenge by: Carl Allchin

Continuing on our fundamental skills theme in May, this week's challenge is all about string calculations. If you want to know more about what String data is and how you might want to work with it, you might want to check out our how to... deal with strings post. Pay particular attention to split, right, mid and find if you're getting stuck with this challenge! I've written another guide to the common functions that you might find use when working with Strings in Tableau. 

The Challenge

This week we are trying to find out more detail on what is going on with the project over runs in Prep Air (every data prepper's favourite airline). To get more detail than just what was shared last week we've uncovered the commentary log that sits behind our project management system. Like any system that holds the detail shown on the programme's interface in a log file, it has great detail but held in an unfriendly way. 

We need your help to get stuck into the messy data and extract out the useful details. 

Input

One Excel file with 5 sheets of data.


There is one main page of data with four lookup tables that will help you change some abbreviations and codes to be full words.

Requirements

There are lots of different ways you can do this challenge so rather than a step-by-step set of requirements, feel free to create each of these data fields in whatever order you like:
  • 'Week' with the word week and week number together 'Week x' 
  • 'Project' with the full project name
  • 'Sub-Project' with the full sub-project name
  • 'Task' with the full type of task
  • 'Name' with the owner of the task's full name (Week 18's output can help you check these if needed) 
  • 'Days Noted' some fields have comments that say how many days tasks might take. This field should note the number of days mentioned if said in the comment otherwise leave as a null. 
  • 'Detail' the description from the system output with the project details in the [ ] 

Output


One file
7 data fields:
  • Week
  • Project
  • Sub-Project
  • Task
  • Name
  • Days Needed
  • Detail

18 rows of data (19 including headers)

Here's our full output for comparison. Remember we don't care about the order of the columns or rows as Tableau Desktop will import them in whatever order they come in!

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!

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 use dif

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
