Key take-aways Data Science Survey

  1. Most companies currently are in the analytical aspiration stage but have the aspiration to improve their data maturity;
  2. Python is the most popular data science programming language;
  3. Microsoft Power BI and SQL are the most common data visualization and- integration tools;
  4. Improving data quality is seen as the biggest challenge for implementing a data-driven way of working.

Data maturity and ambitions

Data maturity

The framework as described in: “Competing on Analytics” by Thomas H. Davenport and Jeanne G Harris is used to determine the data maturity of the different companies. This framework distinguishes 5 stages of data maturity:

Stage 1: Analytical Impaired
“Organization has some data and management interest in analytics. “

Stage 2: Localized analytics
“Functional management builds analytics momentum and executives’ interest through application of basic analytics”

Stage 3: Analytical aspiration
“Executive commit to analytics by aligning resources and setting a timetable to build a broad analytical capability”

Stage 4: Analytical companies
“Enterprise-wide analytics capability under development; top executives view analytic capability as a corporate priority”

Stage 5: Analytical competitors
“Organization routinely reaping benefits of its enterprise-wide analytics capability and focusing on continuous analytics renewal”

Our survey investigates in which stage companies are, based on seven different aspects that are shown in the image below. Click here or on the image to view the full image.

The results show that most companies are in stage 3, but 95% have the ambition to move to the next level or stay at the current stage.

One of the survey’s goals is to investigate how companies in different stages perform in the seven different aspects that determine the data maturity stage. Companies in stages 1-3 are compared with companies in stages 4 & 5. The results showed that companies who want to move past the third stage should improve in all aspects. This is in line with the general idea that if a company wants data science to be a competitive advantage source, they should embrace it in the whole company. Although it is important to improve all aspects, a few need some extra attention:   Data, Analytical techniques, and the Enterprise.

Data investments

To better understand how companies plan to reach the next stage, the survey questioned them about their planned investments in the upcoming year and in three years. The outcome shows that in the upcoming year, companies heavenly invest in data structure and data structuring. This is a logical first step since this is the foundation for further data analysis.

When analyzing the investment in the three-year horizon, it is clear that the investments shift from data quality and -structure to predictive data analysis, data integration, and prescriptive data analysis.
