Explaining that although data science is called 'the most sexy job', most of the work is data wrangling (data is cheap, labeling is expensive). It means hard work to get it to work on a day to day basis. Did you know that data scientist spend around 60% of their time on cleaning and organizing data?** ## It all starts with the domain expert ![TUe lecture - real world data science use cases](https://blogs.itility.nl/hs-fs/hubfs/TUe%20lecture%20-%20real%20world%20data%20science%20use%20cases.jpeg?width=282&name=TUe%20lecture%20-%20real%20world%20data%20science%20use%20cases.jpeg)For every project we start with defining the business problem of the domain expert. When the current situation is summarized, it is important that our perception of the business situation is correct and validated. The problem is then translated into solutions (decomposed into sub tasks) getting results fast in order to fail fast.  ![TUe lecture real world data science use cases 2](https://blogs.itility.nl/hs-fs/hubfs/TUe%20lecture%20real%20world%20data%20science%20use%20cases%202.jpeg?width=282&name=TUe%20lecture%20real%20world%20data%20science%20use%20cases%202.jpeg)This workflow - starting small, working agile, but always with the end in mind - focuses on an operationalized, working model that is used on a day-to-day basis.
