Today everybody recognizes the importance and added value of data for your Business model, if applied well. Whole Industries are changing: think of companies like Amazon, Uber, Netflix and Walmart. Data is high-prioritized at more and more organizations strategy agendas. They hire (interim) professionals who can collect, analyze, model and visualize (Big) Data. Both these companies and their clients trust on reliable, complete, correct and on-time delivered information. Not just one time, but continually. Data professionals can provide this trust by using methods from the field of quality assurance and testing. So, where to start? In this practical course you will get insights to a structured testing approach in complex Data & Analytics projects.

The course is set up in such a way that enables both data professionals and professionals to share ‘a common language’ regarding testing in Data & Analytics environments. Accordingly, the student will learn how to embed structured testing to reach and improve the quality goals.

The course combines theory with practice and contains many exercises which connects the student with practice and delivers the most applicability.
