Be Insights Driven! Why we should not just be Data Driven, and definitely not Tool Driven. #PowerBI, #Tableau, #Qlik

Posted on by

I presented at a ‘BI without the BS’ event in London in November 2018. The idea was that there would be three tools and three players; Qlik, Tableau and Power BI, a judging panel, and a live audience of about 100 people. I represented Power BI and it was very clear that only a few people had seen it before.

As a data visualization person, I’m all about making things clear for people and that was why my story was much simpler and the facts were compelling, displayed in Power BI; I told a story which had a call to action.

My interpretation of the rules

My interpretation of the rules was that data storytelling was one of the main judging criteria. I had not seen the event as a product demo, and that’s why I emphasized the insights that Power BI gave me over knobs and levers that each tool can do. Product demos are easy, but not everyone can find insights in data.

Google Chief Economist Hal Varian predicted that data storytellers are the future over a decade ago. With data as the new oil, every company is seeking new ways to monetize their data. So my emphasis had been on data storytelling with a particular tool, but not trying to sell the tool itself as a demo. That’s my boxing ring to play in, and that’s the hard part of working with data.

An Equal Playing Ground for Games?

For my Power BI piece, my insights were all about the complexities in being a woman in gaming. My Power BI analysis showed that women earned just $1.8m in prize money in total, but the top male game winners earned $145m in total. See the tiny pink sliver? That’s the proportion that women earn in gaming competitions. If you’re thinking, that’s not a good dataviz to show, I can barely see the sliver – then you have missed the point. The point is, it is a tiny sliver. For colours, I have used Dark Orchid to represent female players, and Teal to represent male data throughout the visualization.

Female vs Male Prize Money in Games

So there was a huge difference. In case you need the numbers:

card

So there is a huge disparity between male and female earnings. Is this because there are less women players? Apparently not. This chart shows that the gap between male and female players is narrowing:

Male vs Female Game Players by trend
In the data, I noted that the players were ranked from 1 to 100, for each gender. So I pitted the men and women together in terms of rank to show how the first ranked male player earned versus the first ranked female player. Here is the chart, in Power BI:

Prize Money by Gender

You can see that the girls’ earnings are practically flat, whereas the male earnings are vastly higher. The gender gap in pay is real, absolutely real.

I also noted that the lowest ranked player still earned more than double what the highest earning female player did. So the data showed lots of insights; it depended if you were willing to see things that made you uncomfortable.

Then, I wondered if there was a relationship between the number of tournaments played, and the prize money won. So, I used the male data here to see if  a reasonable relationship could be inferred between the number of tournaments played, and the amount of prize money earned. If women are playing less tournaments, then naturally they will earn less. So how did that pan out?

Relationship between No of Tournaments and Game Prize Money

The interesting thing was that the total number of tournaments played (on the X axis) didn’t seem to impact the amount of prize money earned. I’d have to do more analysis but you can see a vague relationship in the hexbin chart, but with a lot of outliers. I might come back and look at that another day, using R and Python or something.

Gaming in Real Life

So my piece was more about exploring the idea that there is no equal playing ground for women in gaming, and that’s certainly borne out by some of women’s experiences in the gaming world. Harassment for women in gaming can involve sexist insults or comments, death or rape threats, demanding sexual favors in exchange for virtual or real money, or even stalking. The GamerGate scandal tells you all you need to know about it, I suppose. Alternatively, you could look at Fat, Ugly or Slutty where women record instances of instances of sexism. Warning; it is not a pretty read. Or women hiding their identity online as a female, which is a safety measure that many women take. The most recent threat against female gamer Anita Sarkeesian was in Logan, Utah on October 15, 2014. She was scheduled to deliver a speech on a Wednesday evening until an anonymous email message arrived a day before, stating that there would be the deadliest school shooting in American history if the event was held. So don’t kid yourself that this isn’t real, and the impact means that many women are excluded from feeling that they can enter competitions in gaming.

Be Insights Driven, not Data Driven, and definitely not Tool Driven

When you analyze data, you bring your own personality and insights to analyzing data. I don’t believe that tools can solve problems; I believe that we have a lot of data, but no insight, information or wisdom unless we do something with the data. I don’t like the phrase data-driven; I prefer insights-driven. Qlik, Tableau or Power BI aren’t going to solve problems for you; they will just display data that hopefully brings about insights. The insights are yours and you can use each tool equally badly if you don’t have a story or a thread, or the data isn’t provoking an insight. We were all given the same data but we got very different results. That wasn’t down to the tool; it was down to the person driving the tool.

What I thought of the Tableau piece

I liked what Chris Love ( LinkedIn ¦ Twitter ) did; he clearly knows his stuff and it was nice to meet him in person. Funnily enough, we used to have the same boss when I had a boss (hello Tom Brown!).

I did find Chris Love’s visualization more interesting because he honed in on the journey of one player from the starting point to his success in winning a lot of money, and the journey was well displayed in Tableau. Chris had a good balance of context and detail, and for me, this was the data story telling piece. Here is the image below, credit to Laura Sandford:

What I thought of the Qlik piece

Nick Blewden ( LinkedIn, not on Twitter) is obviously fantastic at Qlikview and he did a good job of showcasing it. To be honest, I felt out of my depth here since it was a whizz tour of the product but since I’m not familiar with Qlik, I felt a bit bludgeoned with chart after chart and I couldn’t see a clear thread; it was information load as I tried to pick up the Qlik lingo as well as follow the story. I understand that Nick’s segment wasn’t aimed at beginners in Qlik and that’s ok with me; he only had five minutes to showcase what he’d done and he did a great job.

I am not familiar with the Qlik product set but a lot of the audience clearly were, and I could hear lots of mutters about ‘good to see he’s showing that feature’. So my perspective here is that of someone who does not know Qlik but who has expertise in Tableau and Power BI.  I can look at Qlik another time, if I choose.

I felt I’d let Power BI down at that point because I had not gone down that route of doing a product demo and I feel really bad about that. I had gone for the analytics and insights part because I’d understood the rules that way, and the audience can see a Power BI demo anytime they like.

One reason for me to present at the event was that I’d seen it as an opportunity to learn more about Qlik from the session, but all I saw was chart after chart. For me, there were lots of business intelligence dashboard and that’s fine and I think that it was a good product demo.

So my lasting takeaway from the Qlik segment is this dashboard was interesting because it showed that it was quick to produce a lot of charts very quickly, but sometimes ‘less is more’. I’m a fan of Stephen Few and he talks about the importance of finding the signal in the noise, and having a ton of charts can simply mean more noise if they are not meaningful. Here is the image below, credit to Laura Sandford:

What I’d like to see next

I think I’d have preferred a larger, more mixed audience. A lot of people seemed to know one another already and I only knew one person in the audience. I’m not part of that community and it was nice to meet new people at the end.

Honestly, I’m not a fan of being shouted at by men I don’t know; it is really unpleasant. I think that the audience members should have the courtesy to refrain from shouting out during the performance. I was really put off with people shouting ‘Come on Qlik!’ and ‘Come on Tableau’ during the event. I didn’t hear a single voice for Power BI, not that it mattered; it really disrupted my thought flows to have people shouting when you’re trying to analyse data and I found it unsettling. Being at a live event isn’t like Gogglebox where the presenters can’t hear you.

So what did I think about the Power BI vs Tableau vs Qlik debate?

So what were my takeaways?

My call to action: be Insights Driven, not Data Driven, and definitely not Tool Driven.

According to the Qlik website ‘Deliver automated insight suggestions that help users see their data in new ways, auto-generating and prioritizing analytics and insights based on the overall data set and a user’s search criteria.’ Demystifying the marketing, it seems as if this means producing a ton of charts really quickly and if that’s what you’re looking for, it certainly did that. My overriding thought was that it can produce lots of charts but I really want to find meaning in charts, and I don’t measure meaning in charts by having as many charts as possible. I just got lost and I actually don’t think that’s good for Qlik.

For Tableau, I’d like to see Tableau become a real enterprise tool and it still feels like a cog in an enterprise wheel to me. I would not do any data prep in Tableau Prep although I do have experience in it; I’d want to use Power BI dataflows to clean data so that the data and the dataflows become part of the enterprise ecosystem.

I build big systems and I need to think big. When I’ve been working for customers, I’ve found it is easier to show ROI with Tableau and Power BI but it has taken longer for people to realize ROI with Qlik.

I am eternally confused by licensing and I find Tableau’s licensing simpler; Power BI and Qlik seem to be way more confusing to me. For Power BI, I always refer the customer back to their Microsoft reseller because they can figure it out for them.

Mental Health in Consultancy: You do You

Posted on by

I was inspired by Mark Christie’s post here, Mental Health in Consultancy. I would like to thank Mark for his honest and inspirational sharing of his story. I’d also like to thank Kenneth Fisher for writing Missing those we’ve lost. With this in mind, I wanted to chat about these harder topics.

Here’s my thoughts: Let your light shine out. Success is doing what you want to do, and living your life as you want. Plenty will poke your nose in to tell you that you are doing things wrong, if you let them. But if you need someone, reach out.

You do You.

Mark talked eloquently about the pressures of being a consultant. Like him, I have chosen this life for myself. I have travelled the world to the point where I wasn’t sure which language I should be speaking (I learned some Swedish and Italian in my twenties, as well as French as part of my postgrad AI degree, but the Swedish and Italian have disappeared from my skill set).

I have very little support around me and I tend to pay for the support that I do have. So, I am a divorced single parent who happens to have chosen to be in front of a crowd rather than in a crowd. So, in the past few weeks, I have been selected to be one of the top Analytics influencers in 2018, and now I have been selected as one of the Top Data Science influencers. To it seems as if life has been good to me.

In fact, quite the opposite. I have been poor, a single parent, a victim/survivor, and bullied, and I have been spectacularly gaslit. And a successful consultant. So how did I move forward?

So here’s my secrets, randomly stated:

Get rid of people around you who are not good to you, or good for you. You don’t have to be uncivil.

Have faith in other people, but also be accepting. They are not stupid. If people aren’t being good to you, believe that others will see it eventually.

Face Forward. When I look back, I am not sure how I survived but I think that the secret is not to look back. You can do that by living meaningfully.

Live meaningfully. I get a kick out of working as a data science volunteer for charities. I meet likeminded people and I have company for a while. I’ve also learned something technical. I’ve also helped people that I haven’t met. Which brings me to my next point.

The people who like you, and who spend time with you, are not your friends. Some of the people who have been a real friend to me are people whom I do not know. So when I needed people around me, many people stepped back.

Success is like a video game. The closer you get to the goal, or the more successful you seem to be, the more haters (or game ‘baddies’) appear. They might be throwing things at you, but they are still behind you. So you need to accept haters and people who plagiarize your ideas as their own. You can just ignore them and strive to be the better person. Disassociate yourself from them. All you can do is say ‘I don’t know that person, I don’t know where they get their information from’ if they are talking about you. Let them rock on. They won’t change or learn.

Think about the war, not the battles. I have found some solace in the Buddhist journey. It has helped me to see over and above the daily battles.  I also find this quote from the Bhagavad Gita speaks to my soul:

O son of Kunti, the nonpermanent appearance of happiness and distress, and their disappearance in due course, are like the appearance and disappearance of winter and summer seasons. They arise from sense perception, O scion of Bharata, and one must learn to tolerate them without being disturbed.
Bhagavad Gita 2.14,
Srila Prabhupada

Be the person you’d like someone else to be for you. It’s hard, and I’ve had to swallow a lot of bile; it has to go somewhere. But the best revenge is success, and if you are having a hard time, just go for it.

Try to be the better person. Don’t react; people will only continue to throw things, and they will reveal their hate.

Oh, and eat well. I like Udo’s Choice oil for balancing out the need for sugar, which can lead to highs and lows in blood sugar, thereby making the world appear darker than it is. Consulting can lead to bad food choices: eating on the go. So try and think about that, and how you can eat better.

Good luck, and like Mark said, please ping me if you’d like to talk. We have to look after other people; it makes us stronger. And I don’t mean silly things like ‘help with a CV’ or ‘let off steam about something trivial’. I mean proper talk about mental health. Kenneth points out to some good ideas and resources.

Fracking For the Rest of Us: Exploring with #PowerBI

Posted on by

Having heard of some of the news about fracking in the BBC news, I decided to try and understand it better. I thought I’d analyse some data, and pop it here.

What is Fracking?

Fracking is described as the hydraulic fracturing, or fracking, is a technique to extract gas and oil from the earth. Liquid is pumped underground at high pressure to fracture shale rock and release gas or oil within. Here is a diagram, courtesy of the BBC:

104057230_shale_gas_extraction_640-nc

Image Credit: BBC

What does Fracking have to do with Earthquakes? A 2011 study showed that it was “highly probable” the test drilling for shale gas caused the tremors at that time. Despite the findings, the UK Government and Cuadrilla decided to proceed.

People are concerned that fracking will cause more earthquakes than expected in their region. The organization responsible for the fracking is called Cuadrilla, and their chief executive Francis Egan commented that he expected more incidents to be recorded because of the sensitivity of the recording equipment used by the company.

This irked me, because it pushed the blame onto the equipment, rather than the fracking itself. So I thought I’d take a look at the data, to see if earthquakes was more prevalent in the Lancashire area.

Let’s look at the earthquake data from the British Geological Survey for the last 100 days. I noted only one error in the data; one of the records records the region as Blackpool.Lancashire with a full stop but the others were reported as Blackpool,Lancashire with a comma. It was trivial to fix the data, so I just did it.

How many earthquakes occurred in the Lancashire area over the last 100 days compared to other areas?

This chart, conducted in Microsoft’s Power BI, is fairly compelling, showing that the top number of earthquakes for the last 100 days took place in the Lancashire region:

1 Fracking Earthquake Count

This chart only shows the top eight regions, so let’s take a look at Lancashire versus the rest of the UK:

2 Fracking Lancashire vs non Lancashire

Ok, so over the last one hundred days, one third have occurred in Lancashire. From the data visualization perspective, yes, it is a pie chart but they are useful and impactful when you have a few slices only, and you want to make an impact.

Over time, what does this really mean?

The chart below shows a huge jump in the number of Earthquakes in Lancashire in October 2018, which is the month when the fracking began. Lancashire earthquakes are denoted in blue:

3 Lancashire vs Non Lancashire last 100 days

So, the chart shows that there were a total of 23 earthquakes in the Lancashire area in October. But when did they actually take place?

Since 15 October, Little Plumpton has been the first UK shale fracking site after the process was halted in 2011. How many of the 23 earthquakes took place from that date onwards? Lancashire earthquakes are given in dark teal blue; other areas are given in lighter blue. Some dates are missing on the X axis because earthquakes did not happen on those dates. You can see that they start in earnest in the second half of the month.

4 Number of Earthquakes in October 2018 from 1 to 27 Oct

We can see from this simple chart that all 23 earthquakes in Lancashire took place from October 18th onwards. Note that the fracking in Lancashire started on 15th October 2018.

Where did these earthquakes occur? Let’s look at the Lancashire earthquakes, with Lancashire highlighted in teal blue:

5 UK Map of Fracking

Let’s zoom in on Lancashire. According to the Cuadrilla site, the fracking takes place at Preston New Road.

According to the data, the earthquakes around Blackpool in October happened at this site here. I have plotted the lat long of the earthquakes, using the British Geological Survey data, and popped it on a map in Power BI and used Bing for the background maps. Note that this is in inexact because the full lat long isn’t provided by the data; it is only rounded data supplied. This is a graphical representation, just to give the reader an idea where the centre is recorded, according to the British Geological Survey data. The data is recorded as ‘Earthquakes around the British Isles in the last 100 days’ and it records seismic activity from the very small to the very large. This map only shows the location, not the severity.

7 Map of Lancashire earthquakes

There are less bubbles than 23 earthquakes total because some of the earthquakes happened repeatedly in the same place, according to the rounded lat and long data. Since it is rounded, it introduces inaccuracies but it’s been given here as an illustration.

Caveat: This map isn’t totally accurate. Future and further work would involve more detailed mapping with something like ArcGIS, and full lat long data, not just rounded. Here is what the data looks like and you can get it here:

The table also shows the magnitude, so some of the movements are recorded as tiny i.e. 0.0 to larger events i.e. 0.8.

8 Data Sample for earthquakes

On Friday 26th October, a Cuadrilla spokesman said: “Micro seismic events such as these result in tiny movements that are way below anything that would be felt at surface, much less cause any harm or damage.”

How does my data compare to the BBC? The BBC have generously provided a map, which matches mine at a high level. Mine is very detailed because I got the lat long data from the British Geological Survey.  Here is the BBC version:

103872955_fracking_640-nc

Power BI made it easy to go through the data, fix an error, and then produce simple graphs, charts and maps to tell a story. I’m not a geological scientist but it seems a simple view of the data should raise serious concerns about the human activity there, and what we are doing to the area.

Lancashire isn’t supposed to have 23 earthquakes in the space of ten days.

I’m not reassured by the Cuadrilla message at all; my argument would be that these ‘tiny movements’ should not be taking place at all and it’s obvious that human activity is doing it.

The data shows that these events wouldn’t be happening if the fracking wasn’t taking place. In Lancashire, 23 earthquakes in the space of less than ten days should be a call to everyone to wake up and stop this activity permanently.

Why Lancashire?

The Lancashire County Council’s decision process on fracking can be found here.  Note that the Council have forecasted and set out a medium term forecast funding gap of £144.084m by the end of the 4 year period (2018/19 –2021/22). Cuadrilla have invested £10m in Lancashire but this is nowhere near the funding gap that the local County Council have projected.

The Government is still looking at ways to replace the money that Lancashire will lose as a result of leaving the EU in terms of the Shared Properity Fund, but, to date, nothing has been sorted for Lancashire. My hunch – and it is a pure guess – that the Lancashire finances need to be sorted somehow and that’s why fracking has been pushed through. Lancashire is running out of options.

In Scotland, there is investment in green energy and you don’t have to look far to see windmills. I don’t see why the good people of Lancashire can’t be afforded the same investment in green energy, with jobs, reskilling and opportunities in the things that we should be great at: community, science, tech and energy. Britain needs jobs and opportunities more than ever, and the North needs to be regarded just as carefully as the South of the UK.

Opinion

My opinion is that between the Brexit debacle and fracking, we are shooting ourselves in the foot in Britain. Any hearkening back to a better age of Britain is just nonsense. We can’t sort ourselves out.

Whether you agree with Brexit or not, we still haven’t managed to get an agreement sorted and we should have done that by now. Hell, we can’t even get our rail and roads sorted. And now we are creating environmental earthquakes because we need the money. That smells of desperation and I’m sure that the stench of it will attract even more of this type of behaviour until something really bad happens.

Microsoft Ignite interview with Kevin Farlee on Azure SQL Database Hyperscale

Posted on by
Azure SQL Database is introducing two new features to cost-effectively migrate workloads to the cloud. SQL Database Hyperscale for single databases, available in preview, is a highly scalable service tier that adapts on demand to workload needs. It auto-scales up to 100 TB per database to significantly expand potential for app growth.
What does this mean? It’s one of the most fundamental changes to SQL Server storage since 7pm. So this is big: big news, and very big data stores. I am very lucky because I got to interviewe Kevin Farlee of the SQL Server team about the latest news, and you can find the video below.

I am sorry about the sound quality and I have blogged so that the message is clear. When I find the Ignite sessions published, I will add in a link as well.
What problem are the SQL Server team solving, with Hyperscale? The fundamental problem is how do you deal with very large databases in the cloud. VLDBs is the problems that people want to do with normal operations. All the problems with VLDBs occur due to the sheer size of data, such as backups, restores, maintenance operations, scaling. Sometimes these can take days to conduct these activities, and the business will not wait for these downtimes.  If you are talking tens of terabytes, that takes day and ultimately Microsoft needed a new way to protect data and VLDBs. The SQL Team did something really smart and rethought very creatively on how they do storage, in order to take care of the issues with VLDBs in the cloud.
So, the Azure SQL Server team did something that is completely in line with one of the main benefits and key features of cloud architecture: they split out the storage engine from the relational engine. Storage implementation was completely rethought and remastered from the ground up. They took the viewpoint over how you would go about architecting, designing and building for these solutions in the cloud, if you were to start from scratch?
The Azure SQL Server database team did a smart thing: Azure SQL Server is using microservices to handle VLDBs.
The compute engine is one microservice which is taking care of it’s role, and then another microservice that is taking care of the logging, and then a series of microservices that handle data. These are called page servers, and they interface at the page level. The page servers host and maintain the data files. Each page server handles about a terabyte of data pages. You can add on as many as you need.
Ultimately, compute and storage are decoupled so you can scale compute without moving the data. This means it’s possible to keep adding more and more data, and it also means that you don’t have to deal with the movement of data. Moving data around when there are terabytes and terabytes of data isn’t a trivial task. The page servers have about a terabyte of data each, and the page servers have about a terabyte’s worth of SSD cache.
The ultimate storage is Azure Blob Storage, because blob storage is multiply redundant and it has features like snapshots, so this means that they can do simultaneous backups by just doing a snapshot across all of the blobs. This has no impact on workload.
Restores
Restores are just instantiating a new set of writeable disks from a set of snapshots, and works with the the page servers and the compute engine to take care of it, working in symphony. Since you’re not moving the data, it is faster.
I’m personally very impressed with the work that the team they’ve done, and I’d like to thank Kevin Farlee for his time. Kevin explains things exceptionally well.
It’s worth watching the video to understand it. As well as the video here, Kevin goes into detail in his Microsoft Ignite sessions, and I will publish more links when I have them.
Community
One advantage in doing the MIcrosoft Community Reporter role is that I get to learn from the experts, and I enjoyed learning from Kevin throughout the video.
It seems to me that the Azure SQL database team have really heard the voice of their technical audience and they’ve worked passionately and hard to tackle these real life issues. I don’t know if it is always very clear that Microsoft is listening but I wanted to blog about it, since I can see how much the teams take on board the technical ‘voice’ from the people who care about their solutions, and who care enough to share their opinions and thoughts so that Microsoft can improve their solutions.
From the Azure architecture perspective, it works perfectly with the cloud computing concept of decoupling the compute and the storage. I love watching the data story unfold for Azure and I’m excited by this news.

Microsoft Ignite interview with Executive Team on #ArtificialIntelligence, #Data, #OpenSource and #Cloud

Posted on by

There were a number of announcements across Azure Data + AI at Microsoft Ignite, and Im delighted to say that I had the opportunity to interview Rohan Kumar, Corporate Vice President, Azure Data at Microsoft, and Eric Boyd, Corporate Vice President, AI at Microsoft.

In the interview, Rohan Kumar and Eric Boyd give their opinions and thoughts to myself and Cathrine Wilhelmsen on the big picture across Data & AI.  I was super excited since it was the first time that these Microsoft executives had been interviewed together and I was particularly interested to see how Rohan and Eric cross-reference each other’s areas. It’s clear that they are working in orchestration as a team, and I’m glad to see that because I do see that data and Artificial Intelligence impact one another so much.

Rohan and Eric talk about the announcements that excited them both, and there was also a good discussion on the role of Open Source at Microsoft, and what role it plays in Microsoft’s Data and Artificial Intelligence story.

There was a great discussion on Eric and Rohan’s thoughts on its role in making insights, Artificial Intelligence and insight-driven analysis real for organizations. Every organization on the planet has got data, and Microsoft are carving a path for the organizations that want to make use of it.

I’m personally interested in Amara’s Law, which states that “We tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run.” So I was interested in Rohan and Eric’s perspectives on what aspects of AI are real versus hype. What is Microsoft doing to make AI real and actionable for customers?

We wrapped up with a great conversation on the Microsoft and Facebook collaboration?, which I personally find interesting.

It was  real life-achievement for me to participate in the Microsoft Ignite Community Reporter team, and it was a real achievement for me to interview the Microsoft Executives. I’d like to thank Rohan Kumar and Eric Boyd for their time and for sharing their wisdom and insights.

I was also glad to be on board with Cathrine Wilhelmsen. Cathrine was a wonderful friend and support throughout the week and she’s not just an expert in her domain, but she’s a very giving person in terms of her friendship and support. So the interview holds special meaning for me since I was glad to have the opportunity to work with her.
