Dear Analyst

There are times when a problem nags at you like a pebble in your shoe. Even when you’re not working on the problem itself, you’re thinking about the problem which make it even worse. Rarely do I come across a Google Sheets/Excel task I cannot solve with formulas, but this one evaded my extensive knowledge (or lack thereof). The reason why this problem kept on nagging at me was because it felt like it should be easy to do. Like it was something I’ve solved before in the past. Or a data manipulation task that should...

When you think of your data warehouse, the “semantic layer” may not be the first thing that pops in your mind. Prior to reading Frances O’Rafferty‘s blog post on this topic, I didn’t even know this was a concept that mattered in the data stack. To be honest, the concept is still a bit confusing to me since I’m not building data warehouses and data products all day. Frances grew up in northern England studying mathematics during the recession. The decision to jump into data was a function of what jobs happened to be available at the time...

If you could only learn one programming language for the rest of your career, what would be it be? You could Google the most popular programming languages and just pick the one of the top 3 and off you go (FYI they are Python, C++, and C). Or, you could pick measly #10 and build a thriving career out of it. Ergest Xheblati didn’t just pick SQL and decide to bet his career on it. He started as a software engineer, held various roles in data, and even became a product manager. After trying these different roles, Ergest would still fi...

This is a replay of an episode from the Make Sense podcast with Lindsay Tabas.

In the 1990s, large enterprises typically bought software in a tops-down approach. IT teams would get get Oracle software or Microsoft Office and get their entire organization to use the software. Since these tools are the default IT “blessed” tools, people start putting everything in these tools. This is why I think most people decide to push everything into Excel even though Excel is primarily meant for financial analysis. When it’s already installed on your computer and everyone knows how to use it...

When you’re organization is small, a centralized data team can take care of all the internal data tooling, reporting, and requests for all departments. As the team grows from 100 to thousands of people, a centralized data team simply cannot handle the number of requests and doesn’t have the domain knowledge of all the departments. Jean-Mathieu Saponaro (JM) has experienced this transformation at Datadog. He first joined Datadog in 2015 as a research engineer. He was part of the inaugural data analytics team which now supports 6,000+ employees. In this episode, he discusses scaling a self-serve analytics tool, moving from ETL...

This is a replay of an episode from the Citizen Development Live podcast with Neil Miller.

Citizen development is a relatively new term I learned about a year ago or so. To me, it’s using no-code tools at scale within a large enterprise. It’s a term that covers the population of people who are not developers, programmers, and software engineers by trade but know how to build apps and workflows to accomplish business-critical tasks. This is the definition of a citizen developer from PMI (Project Management Institute):

Low-code or no-code development is the crea...

I wasn’t sure if this topic should be it’s own episode but it’s been on my mind ever since I came back from Atlassian Team ’24 (Atlassian’s annual conference). At the conference, I had the opportunity to meet with a few people who are just as interested in spreadsheets as I am. We talked specifically how Jira can best work with spreadsheets (Excel or Google Sheets) and different workflows that result from the combination of these two tools. It was fascinating to hear how company culture and old ingrained way of doing things leads to the usage of s...

With an undergraduate degree in zoology and a master’s in public health, you wouldn’t expect Amanda Makulec to lead a successful career in data analytics and data visualization. As we’ve seen with multiple guests on the podcast, the path to a career in data analytics is windy and unexpected. It was the intersection of public health and data visualization that got Amanda interested in data visualization as a career. In one of her roles, Amanda was supporting USAID by analyzing open data sets and creating charts and graphs for publishing content. Her team consisted of graphic design...

Sometimes pop culture and data analysis meet and the result is something interesting, thought-provoking, and of course controversial. How can one use data to prove definitely which Taylor Swift songs are the most underrated? Isn’t this a question for your heart to answer? Andrew Firriolo sought to answer this question over the last few months and the results are interesting (if you’re a Taylor Swift fan). As a Swiftie since 2006 (moniker for Taylor Swift fans), Andrew wanted to find a way to bridge his passions for Taylor Swift and data analysis. He’s currently a senior data analys...

We sometimes forget that a large organization is composed of groups and divisions. Within these groups, there are teams and individuals looking to advance their careers. Sometimes at the expense of others. When your advancement depends on the success of your project, the benefits of that project to your company may be suspect and the tools you use to complete that project may not be the best tools for the job. Alex Kolokolov started his journey in data like many of us: in Excel. He moved on to Power BI, PowerPivot, PowerQuery, and building data visualizations for the last 15...
