Week 17: Timesheet checks

Challenge by: Pat Lucas (@PatForData)

This challenge came about from a challenge Pat received as his friends and family have begun to learn about his super data preparation skills. Pat has built out a detailed set of requirements so this might be an easier challenge for some.

The Challenge

My employees log their hours daily and are contracted to 8 hours per week so I want to check their average number of hours worked over the last 2 weeks. Also, I allow for 20% of their time (not including Chats) to work on their own special projects, meaning they should be spending at least 80% of their time on Client items of work, so I also want to check that they are sticking to instructions by calculating the % of total hours spent on Client work. The task has three sets of requirements as the stakeholder is quite specific.

Input

One file but three people's data:


Requirements

  • Remove the ‘Totals’ Rows
  • Pivot Dates to rows and rename fields 'Date' and 'Hours'
  • Split the ‘Name, Age, Area of Work’ field into 3 Fields and Rename
  • Remove unnecessary fields
  • Remove the row where Dan was on Annual Leave and check the data type of the Hours Field.
  • Total up the number of hours spent on each area of work for each date by each employee.

  • First we are going to work out the avg number of hours per day worked by each employee
  • Calculate the total number of hours worked and days worked per person
  • Calculate the avg hours and remove unnecessary fields.

  • Now we are going to work out what % of their day (not including Chats) was spend on Client work.
  • Filter out Work related to Chats.
  • Calculate total number of hours spent working on each area for each employee
  • Calculate total number of hours spent working on both areas together for each employee
  • Join these totals together
  • Calculate the % of total and remove unnecessary fields
  • Filter the data to just show Client work
  • Join to the table with Avg hours to create your final output

Output



One file:
    4 fields:
  • Name
  • Area of Work
  • % of Total
  • Avg Number of Hours worked per day
    3 rows (4 rows including headers)

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 ...
