Rumsfeld on Analytics:

Standard

I loved the “Donald Rumsfeld on Analytics” framework shared by Avinash Kaushik in his strata talk. Even though the talk was from 5 years back, this is still relevant today! As a data analyst/data science professional, we should strive to automate the fact-checking and reporting as much as we can, so that we can focus on the good stuff: validating (or invalidating) intuition and exploring unknowns!

Rumsfeld on Analytics

And if you like frameworks to structure your thoughts, you might also like the What-why-What’s-Next (4W) framework to test your analytics maturity here — this is important because if your organization is not mature, you might get stuck in data puking (reporting/fact-checking) and never get to the good stuff that Avinash talks about in the framework above. So figure out the analytics maturity of your organization and then take steps to help your organization improve.

What are the must-know software skills for a career in data analytics after an MBA?

Standard

SQL, Excel & Tableau-like tools are good enough to start. Then add something like R eventually. And then there are tools that are specific to the industry – example: Google Analytics for the tech industry.

Other than that, you should know what do with these tools. You need to know following concepts and continuously build upon that as the industry use-cases and needs evolve:

  1. Spreadsheet modeling
  2. Forecasting
  3. Customer Segmentation
  4. Root cause Analysis
  5. Data Visualization and Dash-boarding
  6. Customer Lifetime value
  7. A/B testing
  8. Web Analytics

What are some of the most important resources a Data analyst needs to know about?

Standard

This question was asked on Quora and here’s my answer:

I will list resources broken down by three categories.

  1. Business Knowledge: As a data analyst, you need to have at least basic knowledge of business areas that you are helping with. For example: if you are doing Marketing Analytics then you need to understand basic concepts in marketing and that will make you more effective. You can do so one of the three ways:
    • On-the-job: Pick up knowledge by interacting with business people and using internal knowledge bases.
    • Online resources: Pick up basics of marketing by taking a beginners course online on a platform like Coursera OR from resources like this: Business Concepts – Bootcamp | PrepLounge.com
    • College/University: If you are at a college/university then you can either audit a course or depending on your major/minor, core business courses might just be part of the curriculum
  2. Communication skills:
    • Public Speaking: Toastmaster’s is a great resource. if you don’t have access to a local Toastmasters club, you should be able to find a course online. Check out Coursera.
    • Data Storytelling: Just listening to someone like Hans Rosling can be very inspiring! The best stats you’ve ever seen . Also, If you search storytelling with data on YouTube, you will see few good talks: storytelling with data – YouTube
    • Problem structuring: If you are able to break down the problem into core components to identify root cause, you will not only increase your speed to insight but your structure will also help you communicate it more effectively. Learn to break down your problems and use that in communicating your data analysis approach. Imagine this list without the three high-level categories — wouldn’t it look like I am throwing random resources at you? By giving it a structure — Tech, Biz, Communication, I am not only able to structure it but also communicate it to you more effectively. More here: Structure your Thoughts – Bootcamp | PrepLounge.com
  3. Tech skills: Read Akash Dugam’s answer: Akash Dugam’s answer to What are some of the most important resources a Data analyst needs to know about? — it’s a nice list. Also, check this out: Learn #Data Analysis online – free curriculum

A great data analyst will focus on all areas and a good data analyst might just focus on tech. Hope that helps!

“4W” framework for assessing your Analytics Maturity:

Standard

Most organizations could benefit from Analytics but before you set the Analytics road-map for your organization, it’s important to figure out your current stage and then build the road-map to achieve your vision. So how do we figure out the analytics maturity of an organization? Let me share a framework to think about this:

I have blogged about “Business Analytics Continuum” before — it’s a great framework to think about Analytics maturity in an organization — BUT the issue is that it’s harder for business people to remember the stages: Descriptive -> Diagnostics -> Predictive -> Prescriptive — And so there’s a simpler (but equally effective) framework that I have been using over past few months (What -> Why -> What’s next aka “3W” framework). And recently at a Microsoft Analytics conference, I saw this framework with an extra “W” which makes total sense that I liked a lot! So i thought I will share that with you all. So here you go — 4W framework:

Stage 1: What Happened?

Stage 2: Why did it happen?

Stage 3: What will happen?

Stage 4: What should I do?

Analytics Framework What Why Whats Next HOW

I hope the framework as you think about your organization’s analytics vision/road-map and stages that you need to go through to help your org succeed with data!

Titanic Data

Standard

Here’s a link to download the Titanic data — http://lib.stat.cmu.edu/S/Harrell/data/descriptions/titanic.html — it’s really useful in analytics and data science projects. You can:

  1. Build a predictive model. Example: https://www.kaggle.com/c/titanic
  2. I also use this data set to create interactive dashboards on tools like Qlik and Tableau to understand their features.

Enjoy!

Qlik sense: How to see Data Load Editor scripts for apps developed by your Team members?

Standard

(This post first appeared on the Qlik Community. here)

Problem:

So you just joined a Business Intelligence Team and one of the responsibilities include building apps for your business users. Eventually, you would have a need to see Data Load editor scripts for apps developed by other members in the team. So what permission do you need to be able to do that?

Credits: darkhorse

Qliksense Version: Enterprise Server 2.0

Source: can’t see a peer’s data load editor scripts

Solution:

This a two-step process.

1) Get “content admin” access (or “higher” level access)

2) Double check if you have access to see data load scripts for ALL apps

Step 1:

The short answer is that you need “Content Admin” permission from your Qlik sense admin…But with this access level, you will have access to other developer’s app via QMC. If you need to do this via HUB as well then you will have to change the content admin role.

Here’s how Serhan ( darkhorse ) explained how to get this done:

QMC–> Security Rules–>Content Admin–> Edit–> Context–> Both in Hub and QMC

Qlik sense management console

Step 2:

Now, once you get the “content” admin access, you might want to double two things:

1) You can get access to data load scripts on published apps — (I was able to do this but there still seems to some open questions around some folks not being able to see the data load scripts for published apps. If this is the case for you, you need to duplicate the app on your “my work” area and see the scripts)

2) You can duplicate apps on your “my Work” area and see scripts — this is also useful if you want to make changes to published apps that are out there.

Conclusion:

I hope this helps you resolve the permission issues and help you collaborate with your team members!
