Business Intelligence Analyst or Data Scientist? What’s the Difference?

Business Intelligence Analyst or Data Scientist? What’s the Difference?

first_imgI am a huge Thomas Davenport fan. His book “Competing on Analytics: The New Science of Winning” was the first book to make organizations aware of the business potential of analytics, even prior to the craziness brought on by Big Data. I happened upon a recent article of his titled “Looking Outward with Big Data: A Q&A with Tom Davenport” and one item from that article really jumped out at me:“Initially, I didn’t see much of a distinction [between business analytics and big data], and I thought that I could kind of rest on my laurels and not write a book about big data—because the fact is that the analytical tools and approaches used are not all that different for big data. But when I started talking to companies and data scientists, I realized that there really were some fairly substantial differences—some that have yet to be fully articulated and some that are already in evidence.”ShareUnderstanding the DifferencesThere are significant differences between a Business Intelligence (BI) analyst and a Data Scientist, but many folks are still confused. I recently received the following email from a follower (Felix) of my blog series that highlights some of the challenges that organizations are wrestling with on this difference in definitions.“Dear Mr. Schmarzo,I recently came across your January 9th blog post entitled “Business Analytics: Moving From Descriptive To Predictive Analytics.”“Our IT department disagrees on the capabilities of OLAP cubes. To me, a cube does not appear useful for parameterized models or most types of scenario analysis. (I am trained in statistics and other forms of financial modeling.) I showed Figure 1 of your blog to my colleagues, but was told that I do not understand OLAP technology.ShareFelix’s dilemma is typical of what I see in organizations that have spent considerable time and money building out their Business Intelligence capabilities. To me, the situation is similar to the construction worker discovering the “saw.” Doesn’t mean that the hammer is no longer important, but the saw and the hammer perform entirely different but complementary tasks.Here was my response to Felix:“Hey Felix, push back on your IT department. There is nothing predictive in OLAP cubes. Cubes are great for slicing and dicing historical data looking for areas of under- and over-performance in the past week/month/quarter, but they don’t answer any of the questions about the future such as: What will be sales for Product X next month? How many customers do we expect to respond XYZ promotion? What is the likelihood that wind turbine A101 will fail within the next 30 days?“Answering questions about the future requires developing predictive models and getting results that are qualified by probabilities and confidence levels. The key difference is that a BI Analyst uses OLAP cubes and other BI tools to report on what happened in the past, while a data scientist uses predictive and prescriptive tools to forecast what might happen in the future.ShareThere is a significant difference between what a traditional BI Analyst does and what a Data Scientist does. And one does NOT replace the other; they are complementary. Figure 1 does a nice job of summarizing the differences and how these two critical roles play off of each other.Figure 1: Differences Between BI Analyst and Data ScientistData Science is different than the traditional Business Analytics in some key areas. For example, data science…uses predictive and prescriptive analytics to predict what might happen using probabilities and confidence levels, not just report tools to report on what did happen.Note: when we’re dealing with historical data, there is a strong desire and need for the data to be 100% accurate. If you have your financial results wrong for the past quarter, folks are likely to go to jail. However predicting performance for the next quarter is usually measured in probabilities and confidence levels (e.g., “There is a 95% confidence that our revenues will come in next quarter between $200M to $212M). is used for dealing with and mitigating the uncertainty in the data. It uses several analytic and visualization techniques to understand where uncertainty may lay in the data, and then uses data transformation techniques to massage the data into a workable form – not perfect, but again not necessary when dealing with probabilities and not absolutes.is able to create as-needed data transformations (versus the traditional ETL process) to put the data into a format so that it can be combined with other data sources in search in insights about customers, products and operations.To quote our Jeffrey Abbott of EMC Global Services Marketing,“The disconnect is that with BI, people take the historical data and extend the trend lines and factor in cyclical factors. It’s slow, manual, and needs to be rebuilt each month/quarter/year. But with data science, we have the ability to automatically build the predictive apps that actively look for certain combinations of data and trigger a prediction of the future. It’s real time, re-usable, continuous, and automated.”ShareSummaryA recent blog “Data Science: The More Data, the Better”, talks about how Federal Reserve Chair Janet Yellen uses a dashboard of job data that doesn’t just rely upon a single measure (unemployment rate) to make economic and labor policy decisions. Instead, she uses a dozen different measures to provide a more holistic, more accurate, and hopefully more actionable view of the United States economic situation. She’s a data scientist at heart that realizes that a single measure of anything complex—whether it’s the U.S. economy or even things like customer satisfaction and predictive maintenance—is oversimplifying something to the point of not being useful or actionable.I have written several blogs trying to highlight the differences between a traditional business analyst and a data scientist, some of which I have listed below.

Bamford dreaming of Chelsea debut

Bamford dreaming of Chelsea debut

first_img Playing under Aitor Karanka, Jose Mourinho’s assistant at Real Madrid, the striker has netted 17 goals in Boro’s promotion push, with those performances seeing him crowned Championship Player of the Year on Sunday evening. It is an accolade which will no doubt catch the eye of those at Chelsea, where Bamford remains determined to make his mark. “At the start of the season, I had a discussion with Chelsea and they decided that out of the clubs that were interested, Middlesbrough would be the best fit,” the England Under-21s international said. “Not only for me as a player but it would make me ready for Chelsea next year or the year after. “At the minute, there’s no reason why I wouldn’t want to be at Chelsea. That’s my dream, to pull on that blue shirt, so hopefully it’ll come true. “It will be a tough task to break into the first team. Most strikers playing in the Premier League regularly are aged around 23 or 24. “At a club like Chelsea they have the money to buy world class strikers like Diego Costa and there’s also that pressure to win trophies, I just have to stick with it, be patient and hopefully my rewards will come.” Bamford clearly sees his long-term future at Chelsea but, while negotiations to extend his contract are ongoing , accepts another loan spell may be beneficial next season. Press Association Like so many young players at Stamford Bridge, the 21-year-old has found the pathway to the first-team blocked and has been farmed out on loan. Bamford spent successful spells at MK Dons and Derby last season, before linking up with Middlesbrough this term – a move which has seen the striker’s game go up a notch. A return to Boro would make sense, especially as it looks like the Riverside Stadium may soon be hosting Premier League football. Friday’s vital 1-0 win at Norwich means only goal difference separates Boro from an automatic promotion spot with two matches remaining. “You can see the work we put in week-in week-out on the training ground and the work everyone puts in,” Bamford said. “We do deserve to go up but I think a lot of teams think the same thing. It’s going to be tight, it’s going to be an exciting finish to be sure.” It is a run-in Bamford hopes to be involved in, having sustained an ankle injury in the win at Carrow Road. The striker somehow battled on but is a doubt for the remaining matches against Fulham and Brighton. “I’ve got a scan (scheduled) and it’s a bit sore but I’ll try and play on,” Bamford said “It was massive win for us at Norwich on Friday. It wasn’t our best game of the season, but we have the best defensive record and you saw why.” Patrick Bamford wants to remain at Chelsea for many years to come and is willing to remain patient to fulfil his dream of playing for the club.last_img read more
