movado19: I'd really love to hear your thoughts on what could be added to the dashboard to make the call to action more glaring... Personally, I feel it's a pretty ok (basic) dashboard and if the analyst in question is a good storyteller, (a key skill)... the dashboard would drive required insight For instance, if I were a decision maker, I'll like to know the agents responsible for the 19% unanswered calls and ask HR or their line managers to relay necessary feedback to them so that answered calls can come up to 98% minimum... I want to know why calls aren't coming in in February and March...I want to know why we have high number of issues on streaming & payment that are unresolved... I'd also ask why we have calls over the weekend for complaints...my customers need to have the weekend to themselves so issues that are coming up over the weekend should be treated so that calls in that period are reduced to the barest minimum (win-win for my employees and customers) And on and on and on... A dashboard is like a gun. The capacity of the gun is quite important but not nearly as important as the skill or ability of the shooter. Decent dashboard for me. 3 Likes |

Kaycee54321: Thanks for the review boss. Really appreciate the insight you extracted from it. The dashboard was simply a descriptive analysis and I strictly followed the project instructions in the course of building the dashboard. Mere looking at it, someone could ask a lot of questions like you just did depending on the audience or purpose. 3 Likes 1 Share |

Kaycee54321:Remind me of the Pearl Harbor movie despite all the analysis, the decision maker was still waiting to be absolutely sure that the Japanese would blow up their ass.. Unfortunately the Analyst can't make the call and that cost a lot of lives. 2 Likes 1 Share |

Raalsalghul: Sure. Data Visualisation is just a means and not the goal itself. To understand the dashboard is the immediate goal. To make good/better decisions is the ultimate goal. Personally looking at the dashboard, a few things stick out to me which could be improved; such as: 1. No of calls. Is this a "No" or "Number"? - The analyst will make the consumer of the dashboard to start guessing/wondering. This is only acceptable if this is just for exploratory visualisation purposes within your team members and NOT for your primary stakeholders. Are the 5000 calls daily, weekly, monthly, or yearly? 2. Answered calls 81%. Is this daily, weekly, monthly, or yearly? Is this by ALL the agents or only the top 5 agents? 3. Un-answered Call. Is it un-answered or unanswered? Is it call or calls? Do unanswered calls mean that they were never answered or that they were never resolved? 4. No of Call Agent. Is it "No" or "Number"? Is it Call Agent or Call Agents? 5. Pickup Speed. Is it the pickup speed of the agents or something else? Is this number an average or some other aggregate? Is this value is seconds or some other time function? Never make your stakeholders think or guess what it is that you are conveying. 6. No. of Unresolved Calls by Topic. The chart heading is not in alignment with the y-axis. The heading is too dark...it should never take the shine away from the chart itself. Its job is to be descriptive enough. The y-axis label (Topic) should be aligned with the first topic (Streaming). The Y-axis label is too small and too dark. It should be in the background and not in your face. The topics are not aligned properly...a lot of shifting and some are broken off, so one can't completely read and comprehend what it means. There should be proper white space between the topics and the chart itself. The chart is lovely as a horizontal bar chart. The chart labels would have been a bit bigger and cleaner if they were centered within the bars...this is not the case, except for the first bar. 7. Trends of Calls Per Month. Are these "Answered Calls" or "Un-Answered Calls"? A better description would have been "Monthly Call Trend", "Call Trend by Month", "Call Trend" and then "Monthly" as a subheading. The chart heading is not in alignment with the y-axis. No need for the x-axis label since the chart descriptor has already done that job for you. Yes, one can see a downward then continuous trend over the three months, but... Where is the story to support the downward trend? Where is the story to support the continuous trend? WHAT exactly do you want the stakeholder(s) to do with this chart? Is it a call to action: to hire more agents? to train the agents better? to shift non-essential work from the agents' plates so they can have more time dedicated to answering calls? where they out sick, hence the drop? Is this to support management's decision to lay off the bottom performers? There is nothing in this chart to point one in a certain direction. 8. Calls Rate round the Week It would be better to use the upper case for only the start of the heading. Since they are just two - weekday and weekend - then a simple text visual to display the call rates respectively would have sufficed. No need for the x-axis as it is sort of redundant here. Again, this would have been an opportunity to support your visual with the appropriate story of: WHY and WHAT decision(s) you would expect the stakeholders to take. Are the agents expected to work on weekends as per the company's policy? Is the weekday rate as expected, above or below average? Is the weekend rate as expected or above or below the average? It is not enough that you create a chart as an analyst...what point are you trying to drive home? 9. Answered calls by Top 5 Agent The heading is not aligned with the y-axis. There should be uniformity in the case type of the chart heading. Since the top 5 agents have almost the same values, then a simple text visual to display their average call would have sufficed. The supporting story for it would have been the names of the 5 agents and what stands them apart. Is this a chart to recommend training for the low-performing agents? Always use a chart to drive home the main reason(s) for its creation via a story. 10. Hourly Calls Trend The heading is not aligned with the y-axis. The y-axis has no explanatory label. A slope graph would have been better for easier visual and understanding. A heat map would have also been a better option for a cleaner visual and better understanding. Again, what message do you want to drive home to the consumers of the visual? There are no pre-attentive attributes to capture the steep downward trend of the last call hour(s). WHAT story narrates the reason for the steep downward trend? WHAT call to action are you proposing to the stakeholders to carry out? It is not enough that you create charts as an analyst... what point are you trying to drive home? what call to action are you proposing? what decision(s) are you trying to influence? Be a change agent in order to set yourself apart. This dashboard maybe be okay in your company for now, but do think about if you were hired in another company to create visuals that will appear in a highly influential international magazine with data-savvy clients across the globe...would your visuals pass, or not? 9 Likes 4 Shares |

Eskhalil: I actually already use Coursera to learn. I just used the ebook to further explain stuff that the Coursera course skipped. I’ll check out the Learn Python the Hard way ebook to see how it compares to Automate the Boring Python. Thanks for the advice chief 1 Like |
