From EDNA’s Call Centres CEO – Mark Phoney

Thank you for engaging in this project with us. We have provided you with a small sample of data, there are some initial requirements that I would like to draw your attention to the following requirements.

Delete a column in the Calls data files named “Call Abandoned”

Create a new column in the Calls data files, name it “SLA Compliance” This column includes a logical statement wherein Calls “Waittime” is less than 35 seconds . Column results must be “Within SLA” or “Outside SLA”

Important Read - Please be alert and ready

The project runs for 45 days (approx.), I can let you know in advanced that as we put a few more bit togethers you will receive further instructions during the project timeline.

These further instructions will materialise in the form of new data to add, tables to integrate within your report or specific visualisations depending on Senior Management preferences . We are aware of how it can affect sudden changes your report sample thus, it is our overall intentions to try no to disrupt your processes and or disrupt as minimum as possible.

When these further instructions may occur

Our project start date is 25/03/2022 - (2022-03-25) and your final reports must be submitted by the **09/05/2022 - (2022-05-09)

We expect these further elements to be introduce between the 3rd and 5th week in the project timeline.

Report Developer Role

@FPastor A Power BI Challenge where you add data over time? That’s something nobody has thought of! Amazing.


@AntrikshSharma - Thanks. Trying to be as close to working reporting as possible!



Great twist for this Challenge! Receiving further instructions during the project timeline happens often in real live. The capacity to adapt and build a resilient & adaptive design is needed, and in order to practice this skill this challenge is perfect!
Good luck everyone! :slight_smile:


Cool topic. I’d try to participate.
@FPastor , I wonder if it’s fine to submit an entry before the updates are released or is it better to wait until all the information is in place?


@alexbadiu Thank you - the idea is to simulate, as much as possible, real work scenarios and this one is the most habitual. You begin a new project with an idea in mind and end with a different one…



@StaceyL Thank you, I know sometimes is difficult to find the time for these extra curriculum activities. As we were told in school, extra curriculum activities are very important and help with your learning experience. Happy if you try your best to participate :+1:.

The report must present all the information required by the brief…we can not go back to an employer with an incomplete report. Thus I suggest waiting until all the information is in place. You can start building your report and be prepared for some adjustments.

On the other hand, I do encourage in time to time screenshots of the progress on your report if you want to share it.

I hope this clarifies,

Federico Pastor


Time to be bold and showcase. Gotta give this one a try! Even a simple one just to loose the fear and get started. Here we go!


@Josimar_Biosse don’t underestimate the power of simplicity :smiley: “Simplicity is the ultimate sophistication” ~ Leonardo Da Vinci.

Come on and join us!!!



Hi Federico,

Please see below feedback received from a participant

I downloaded it and within an hour I was able to see that the scale is way off. Like 20-30X off. For that call volume, a company would only need 3-5 Employees in 1 Center, not 90 with 12 managers in 3 Centers. They are only taking an avg of 1.5 calls/day/ee for 12 minutes each. This makes making a sensible analysis and recommendations to management much more difficult.

The other thing is that the data is far too “flat”: there is very little variation by Employee for productivity, avg call time, % abandoned, avg wait time - so you can’t gain many insights. A visualization with everyone “nearly equal” or in a very tight range, is not very informative. Also there is no meaningful seasonality to the time dimension, and the sales/tech support/billing call mix % is nearly identical in all contexts. I didn’t put cost $ to this per se, but back of the envelope indicates it’s costing about $100/call which should be more like $3-$5.

If the idea is to get newer analysts involved and interested, having weak/flat visualizations and filters could be a negative instead of a positive - a smart analyst would say, “why bother?” when there is so little insight to be gained.

Is it too late to change the data? Thanks



Thank you Kim.

The role of a data analyst is to analyze the data brought forward to him/her. Skilled analysts are excellent at exploring data quickly and transforming it into meaningful, data-driven recommendations. There is a small catch no matter how smart the data analyst is, his/her skills does not guarantee impact. We should remain constantly about this fact otherwise we will tend to distort the facts and start blurring into meaning that it is not in the data.

The brief also makes indication about further data to be added, this may be the changes the participant is looking for, I can’t guarantee this will produce the effect wanted.

The dataset, in its current state, presents a great opportunity to use different transformations to enhance the dataset and ultimately present what the data brings to the table.

I hope this clarifies,



“Simplicity is the ultimate sophistication” ~ Leonardo Da Vinci.
I have this quote on my computer monitor as a constant reminder. It is easy to make a system complex, it is quite complex to make something look and act simply.


@jgriffit I could not agree with you more!!! I live by this motto.




@FPastor, is it possible to confirm the desired outcome of this action? Should we just ignore abondoned calls’ status or should we delete all the abandoned calls?


It came out as a surprise for me that the abandoned calls’ ‘call duration’ time is not zero. I also was wondering isn’t the data too flat.


@StaceyL Thanks for your questions.

The Brief indicates to delete the column “Call Abandoned” and substitute with a new Colum called “SLA Compliance” - definition in the brief.

Your role in the Challenge is to analyse the data provided.

I hope this clarifies.

Federico Pastor



When working on a project, I don’t normally question the flatness of the dataset provided by a client, I just analyse it and present my findings (if any) to the client in the best possible way.

Still, there is more data to come, it may/may not make less flat but this is the dataset to be analysed.




Hi @FPastor . Very good to have a Data Dictionary. It makes things quicker and simpler. Thanx



Thanks, all our challenges from now on will be accompanied by a data dictionary and any other indication, as necessary, to ensure the Challenge Brief is self-explanatory. At the same time, please feel free to ask as many questions as you want to ( 3 Max per Challenge :sunglasses: )
