data quality horror stories

Tell me some data quality horror stories.
A financial institution once had a data quality nightmare. They were relying on data for risk assessment. However, the data on customers' income was inaccurate. Some incomes were over - reported and some were under - reported. This led to incorrect risk evaluations. Loans were given to high - risk customers who couldn't afford to pay back, and some reliable customers were denied loans. It was a disaster for the bank's reputation and finances.

What are the common elements in data analytics horror stories?
Well, a major common element is the rush to get results. When teams are under pressure to produce quick analytics, they may cut corners. This could involve not doing thorough data cleaning, skipping proper testing of algorithms, or not validating data sources. Also, poor communication between different teams involved in data analytics can lead to horror stories. For example, the data collection team may not communicate the limitations of the data to the analysis team, which can then make wrong assumptions based on that data.

What are the common D365 horror stories related to data loss?
Another case is when human error occurs. A user might accidentally delete important data in D365. This could be due to a lack of understanding of the system or just a simple mistake. And if the deletion is not noticed immediately and there are no recovery mechanisms in place, that data could be permanently lost. Also, if there are issues with the D365 database itself, like corruption, it can lead to data loss. This might happen if there are hardware problems on the server where the D365 database is stored.

What are the key elements in data analytics success and horror stories?
In success stories, accurate data collection is key. If you start with good data, your analysis is likely to be more reliable. For example, a retail store that collects accurate sales data can better forecast trends. In horror stories, often poor data quality is the culprit. Bad data leads to wrong conclusions. For instance, if a survey has a lot of false responses, any analysis based on it will be off.

One horror story is when a company misinterpreted data on customer satisfaction. They thought the high numbers in a particular metric meant great satisfaction. But in reality, the data collection was flawed. The questions were leading and the sample size too small. As a result, they made big changes to their product based on false positives, and it led to a huge drop in actual customer satisfaction.
